Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates —The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents —Cash and cash equivalents include all highly liquid investments with original maturities of ninety days or less. The Company reclassifies cash overdrafts to accounts payable. Accounts Receivable —Through Nutri-Force, the Company sells product to third-party wholesale customers. The Company monitors the financial condition of its third-party wholesale customers and establishes an allowance for doubtful accounts for balances estimated to be uncollectible. In addition, customer allowances including promotional discounts and allowances are provided to wholesale customers based on various contract terms and are recorded as a reduction to revenue. The following table details the activity and balances for the Company’s customer allowances for the years ended December 31, 2016 , December 26, 2015 and December 27, 2014 (in thousands): Balance at Beginning of Fiscal Year Additions Deductions Balance at End of Fiscal Year Period Ended December 31, 2016 $ 897 $ 3,097 $ (2,933 ) $ 1,061 Period Ended December 26, 2015 $ 1,883 $ 2,752 $ (3,738 ) $ 897 Period Ended December 27, 2014 $ — $ 3,194 $ (1,311 ) $ 1,883 Inventories —Inventories are stated at the lower of cost or market value. Cost is determined using the weighted average method. Finished goods inventory includes costs of freight on internally transferred merchandise, and costs associated with our buying department and distribution facilities, as well as manufacturing overhead which are capitalized into inventory and then expensed as merchandise is sold. In addition, the cost of inventory is reduced by purchase discounts and other allowances received from certain of our vendors. The Company estimates losses for expiring inventory and the net realizable value of inventory based on when a product is close to expiration and not expected to be sold, when a product has reached its expiration date, or when a product is not expected to be saleable. In determining the reserves for these products, consideration is given to such factors as the amount of inventory on hand, the remaining shelf life, current and expected market conditions, historical trends and the likelihood of recovering the inventory costs based on anticipated demand. The following table details the activity and balances for the Company’s reserve for inventory for the years ended December 31, 2016 , December 26, 2015 and December 27, 2014 (in thousands): Balance at Beginning of Fiscal Year Amounts Charged to Cost of Goods Sold Write-Offs Against Reserves Balance at End of Fiscal Year Fiscal Year Ended December 31, 2016 $ 7,253 $ 11,067 $ (9,707 ) $ 8,613 Fiscal Year Ended December 26, 2015 (1) $ 5,797 $ 11,088 $ (9,632 ) $ 7,253 Fiscal Year Ended December 27, 2014 (1) $ 2,640 $ 8,764 $ (5,607 ) $ 5,797 (1) Fiscal 2015 and Fiscal 2014 figures have been restated to include the reserve for inventory of Nutri-Force. Property and Equipment, Net —Property and equipment, net is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided for on a straight-line basis over the estimated useful lives of the related assets. Furniture, fixtures and equipment are generally depreciated over seven years . Leasehold improvements are amortized generally over the shorter of their useful lives or related lease terms. The direct internal and external costs associated with the development of the features and functionality of the Company’s website, transaction processing systems, telecommunications infrastructure and network operations, are capitalized and are amortized on a straight line basis over the estimated useful lives of generally five years . Capitalization of costs begins when the preliminary project stage is completed and management authorizes and commits to funding the computer software project and that it is probable that the project will be completed and the software will be used to perform the function intended. Depreciation of the assets commences when they are put into use. Expenditures for repairs and maintenance are expensed as incurred and expenditures for major renovations and improvements are capitalized. Upon retirement or disposition of property and equipment, the applicable cost and accumulated depreciation are removed from the accounts and any resulting gains or losses are included in the results of operations. Impairment of Long-Lived Assets —The Company reviews its long-lived assets for impairment whenever events or changes in circumstances, including store closures, indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset to undiscounted pre-tax future net cash flows expected to be generated by that asset. If the undiscounted future cash flows are not adequate to recover the carrying value of the asset, an impairment loss is recognized for the amount by which the carrying amount of the assets exceeds the fair value of the assets. Goodwill and Other Intangibles —Goodwill and other indefinite-lived intangibles are not amortized. Evaluations for impairment are performed at least annually, in the fourth quarter of each year, or whenever impairment indicators exist. Goodwill is evaluated for impairment at the reporting unit level (the Company’s operating segments). The evaluation of goodwill and other indefinite-lived intangibles may first consider qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value is less than its carrying value. A quantitative evaluation is performed if the qualitative evaluation results in a more likely than not determination or if a qualitative evaluation is not performed. The Company’s quantitative impairment tests involve calculating the fair value of each reporting unit using the discounted cash flow analysis method along with the market multiples method which is used for additional validation of the fair value calculated. These valuation methods require certain assumptions and estimates be made by the Company regarding certain industry trends and future profitability. It is the Company’s policy to conduct goodwill impairment testing from information based on current business projections, which include projected future revenues and cash flows. The cash flows utilized in the discounted cash flow analysis are based on five-year financial forecasts developed internally by management. Cash flows for each reporting unit are discounted using an internally derived weighted average cost of capital which reflects the costs of borrowing for the funding of each unit as well as the risk associated with the units themselves. If the carrying amount of a reporting unit exceeds its fair value, the Company would compare the implied fair value of the reporting unit goodwill with its carrying value. To compute the implied fair value of goodwill, the Company would assign the fair value of the reporting unit to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. Also as part of the quantitative test, the Company conducts the test using a 10% decrease in its revenue projections as an additional sensitivity test to ensure the reporting unit’s fair value is greater than its carrying value should events in the future be less favorable than anticipated. For indefinite-lived tradenames, we utilize the royalty relief method in our quantitative evaluations. Under the royalty relief method, a royalty rate is determined based on comparable licensing arrangements which is applied to the revenue projections for the applicable indefinite-lived tradename and the fair value is calculated using a discounted cash flow analysis. To the extent that the implied fair value associated with the goodwill and indefinite-lived intangible assets is less than the recorded value, this would result in a write down of the carrying value of the asset. Impairment tests between annual tests may be undertaken if an event occurs or circumstances change that could reduce the fair value of a reporting unit below its carrying value. The valuation of the goodwill and indefinite-lived intangible assets is affected by, among other things, the Company’s projections for the future and estimated results of future operations. Changes in the business plan or operating results that are different than the estimates used to develop the valuation of the assets may impact these valuations. For those intangible assets which have definite lives, the Company amortizes their cost on a straight-line basis over their estimated useful lives, the periods of which vary based on their particular contractual terms. In Fiscal 2016, the Company performed a quantitative analysis of its retail and direct reporting units and determined that the fair value of these reporting units was greater that their respective carrying values. As a result, the Company believes the fair values of each of these reporting units and indefinite-lived tradenames substantially exceeds their respective carrying values. During Fiscal 2016, the Company also performed quantitative analyses of its manufacturing reporting unit and determined the carrying value of the manufacturing reporting unit exceeded its fair value, which resulted in the write-off of the corresponding goodwill of $32.6 million and the customer relationship intangible asset of $6.6 million . Refer to Note 5. Goodwill and Intangible Assets for additional information. There have been no impairment charges related to goodwill or other intangibles during Fiscal 2015 and Fiscal 2014 . Rent Expenses, Deferred Rent and Landlord Construction Allowances —Rent expense and rent incentives, including landlord construction allowances, are recognized on a straight-line basis over the lease term. The Company records rent expense for stores, distribution centers and manufacturing facilities as a component of cost of goods sold. The Company accounts for landlord construction allowances as lease incentives and records them as a component of deferred rent, which is recognized in cost of goods sold over the lease term. Revenue Recognition —The Company recognizes revenue when merchandise is sold “at point of sale” in retail stores or upon delivery to a direct customer. In addition, shipping fees billed to customers are classified as sales. Amount recognized as shipping revenue during Fiscal 2016 , Fiscal 2015 and Fiscal 2014 , were $2.2 million , $2.0 million and $3.0 million respectively. Nutri-Force sells product primarily to third-party customers and to our retail and direct segments. Wholesale revenue is recognized when risk of loss, title and insurable risks have transferred to the customer, net of estimated returns and allowances. To arrive at net sales, gross sales are reduced by deferred sales, customer discounts, actual customer returns and a provision for estimated future customer returns, which is based on management’s review of historical and current customer returns. Sales taxes collected from customers are presented on a net basis and as such are excluded from revenue. Cost of Goods Sold —The Company includes the cost of inventory sold, costs of warehousing, distribution, manufacturing and store occupancy costs in cost of goods sold and excludes depreciation and amortization related to the retail and direct segments, which is included within selling, general and administrative expenses. Warehousing, distribution and manufacturing costs, which are capitalized into inventory and then expensed as merchandise is sold, include freight on internally transferred merchandise as well as for shipments to direct and wholesale customers and costs associated with our buying department and distribution facilities, as well as manufacturing overhead. Store occupancy costs include rent, common area maintenance, real estate taxes and utilities. Vendor Allowances —Vendor allowances include discounts, allowances and rebates received from vendors and are based on various contract terms. Vendor allowances are recognized as either purchase discounts which represent a reduction of product cost, funding which is capitalized into inventory and recognized in the statement of income as the merchandise is sold, or direct offset which represents funding subject to immediate recognition in the statement of income, depending on the nature of the allowance. Frequent Buyer Program —The Company has a frequent buyer program (“Healthy Awards Program”), whereby customers earn points toward free merchandise based on the dollar volume of purchases. Beginning in Fiscal 2016, points are earned each calendar quarter and must be redeemed within the subsequent calendar quarter or they expire. In previous years, points were earned each calendar year and must be redeemed within the first three months of the following year or they expire. Sales are deferred at the time points are earned based on the value of points that are projected to be redeemed, which are based on historical redemption data. The Company records a liability in the period points are earned with a corresponding reduction of sales. Store Pre-opening Costs —Costs associated with the opening of new retail stores and start up activities are expensed as incurred. Advertising Costs —The costs of advertising for online marketing arrangements, magazines, direct mail and radio are expensed as incurred, or the first time the advertising takes place. Advertising expense was $21.9 million , $21.6 million and $19.3 million for Fiscal 2016 , Fiscal 2015 and Fiscal 2014 , respectively. Online Marketing Arrangements —The Company has entered into online marketing arrangements with various online companies. These agreements are established for periods of 24 months , 12 months or, in some cases, a lesser period and generally provide for compensation based on revenue sharing upon the attainment of stipulated revenue amounts, a percentage of the media expenditure managed by the online partner, or based on the number of visitors that the online company refers to the Company. The Company had no fixed payment commitments during Fiscal 2016 , Fiscal 2015 and Fiscal 2014 . Income Taxes —Deferred income tax assets and liabilities are recorded in accordance with the liability method. Deferred income taxes have been provided for temporary differences between the tax bases and financial reporting bases of the Company’s assets and liabilities using the tax rates and laws in effect for the periods in which the differences are expected to reverse. The Company accounts for tax positions based on the provisions of the accounting literature related to accounting for uncertainty in income tax positions. Such literature provides guidance for the recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For tax positions that are not more likely than not sustainable upon audit, the Company recognizes the largest amount of the benefit that is more likely than not to be sustained. The Company makes estimates of the potential liability based on our assessment of all potential tax exposures. In addition, the Company uses factors such as applicable tax laws and regulations, current information and past experience with similar issues to make these assessments. The tax positions are analyzed regularly and adjustments are made as events occur that warrant adjustments for those positions. The Company records interest expense and penalties payable to relevant tax authorities as income tax expense. Concentrations of Credit Risk —Financial instruments, which potentially subject the Company to concentrations of credit risk, include accounts receivable from wholesale customers as well as debit and credit card processors of retail transactions. As of December 31, 2016 and December 26, 2015 , five customers represented approximately 58% and 53% , respectively, of the accounts receivable from wholesale customers. Accounts receivable from debit and credit card processors, included in prepaid expenses and other current assets on the consolidated balance sheets, totaled $10.6 million at December 31, 2016 and $10.2 million at December 26, 2015 . The Company had one supplier from whom we purchased at least 5% of our merchandise during Fiscal 2016 , two suppliers from whom we purchased at least 5% of our merchandise during Fiscal 2015 and one supplier from whom we purchased at least 5% of our merchandise during Fiscal 2014 . We purchased approximately 11% of our total merchandise from these suppliers during Fiscal 2016 and approximately 17% during Fiscal 2015 and 12% during Fiscal 2014 . The Company is subject to concentrations of credit risk associated with cash and cash equivalents, and at times holds cash balances in excess of Federal Deposit Insurance Corporation limits. Stock-Based Compensation —Stock-based compensation cost is measured at the grant date based on the fair value of awards and is recognized as expense on a straight-line basis over the requisite service period for each separately vesting portion of the award, net of anticipated forfeitures. With the exception of restricted shares, performance share units and restricted share units, determining the fair value of stock-based awards at the grant date requires considerable judgment, including estimating expected volatility, expected term and risk-free rate. Compensation expense resulting from the granting of restricted shares, performance share units and restricted share units is based on the grant date fair value of those common shares and is recognized generally over the two to three year vesting period for restricted shares, the approximately three year vesting period for performance share units and over the quarterly or one year vesting periods for restricted share units. For accounting purposes, the expense for performance based stock options, performance based restricted shares and performance share units is calculated and recorded, based on the determination that the achievement of the pre-established performance targets are probable, over the relevant service period. The vesting requirements for performance based stock options and performance based restricted shares permit a catch-up of vesting at the end of the vesting period. Expense related to shares purchased under the Company’s Employee Stock Purchase Plan (“ESPP”) is accounted for based on fair value recognition requirements similar to stock options. ESPP participation occurs each calendar quarter (the “Participation Period”) and the expense of which is subject to employee participation in the plan. Under the ESPP, participating employees are allowed to purchase shares at 85% of the lower of the market price of the Company’s common stock at either the first or last trading day of the Participation Period. Compensation expense related to the ESPP is based on the estimated fair value of the discount and purchase price offered on the estimated shares to be purchased under the ESPP. Expense is calculated quarterly, based on the employee contributions made over the applicable three-month Participation Period, using volatility and risk free rates applicable to that three -month period. Net Income Per Share —The Company’s basic net income per share excludes the dilutive effect of stock options, unvested restricted shares, unvested performance share units and unvested restricted share units. It is based upon the weighted average number of common shares outstanding during the period divided into net income. Diluted net income per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. Stock options, unvested restricted shares, unvested performance share units, warrants and unvested restricted share units are included as potential dilutive securities for the periods applicable, using the treasury stock method to the extent dilutive. The components of the calculation of basic net income per common share and diluted net income per common share are as follows (in thousands except share and per share data): Fiscal Year Ended December 31, 2016 December 26, 2015 December 27, 2014 Numerator: Net income $ 24,964 $ 53,171 $ 61,241 Denominator: Basic weighted average common shares outstanding 23,875,540 28,954,804 30,239,183 Effect of dilutive securities: Stock options 68,272 97,114 235,057 Restricted shares 115,287 150,353 184,995 Performance share units 7,173 — — Restricted share units 1,414 1,158 4,870 Diluted weighted average common shares outstanding 24,067,686 29,203,429 30,664,105 Basic net income per common share $ 1.05 $ 1.84 $ 2.03 Diluted net income per common share $ 1.04 $ 1.82 $ 2.00 Stock options, restricted shares and performance share units for the fiscal years ended December 31, 2016 , December 26, 2015 and December 27, 2014 for 24,140 , 48,538 and 18,089 shares, respectively, have been excluded from the above calculation as they were anti-dilutive. The Company has the intent and ability to settle the principal portion of its Convertible Notes in cash, and as such, has applied the treasury stock method, which has resulted in the underlying convertible shares being anti-dilutive in Fiscal 2016 and 2015 as the Company’s average stock price from the issuance of the Convertible Notes through December 31, 2016 was less than the conversion price. Refer to Note 8. Credit Arrangements for additional information on the Convertible Notes. Recent Accounting Pronouncements — Except as noted below, the Company has considered all new accounting pronouncements and has concluded that there are no new pronouncements that may have a material impact on its results of operations, financial condition, or cash flows, based on current information. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). Under ASU 2014-09, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of ASU 2014-09 by one year. ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017 for public companies and early adoption of ASU 2014-09 is permitted for public companies for annual reporting periods beginning after December 15, 2016. The Company currently expects this guidance will not have a material impact on the Company's consolidated financial statements. However, the Company is still evaluating ASU 2014-09 including the determination of the transition approach it will utilize. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), Leases (Topic 842). ASU 2016-02 was issued by the FASB to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. ASU 2016-02 will require modified retrospective application at the beginning of our first quarter of Fiscal 2019, but permits adoption in an earlier period. The Company currently expects this guidance will not have a material impact on the Company's results of operations. However, the Company is still evaluating ASU 2016-02 in order to determine the impact of this guidance on the Company’s balance sheet and anticipates this guidance will result in a significant increase to long-term assets and liabilities given we have a significant number of leases. In March 2016, the FASB issued Accounting Standards Update No. 2016-09 (“ASU 2016-09”), Compensation-Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 addresses simplification of several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of ASU 2016-09 is permitted. The Company has evaluated ASU 2016-09 and does not expect the impact of this guidance to have a material impact on the Company's consolidated financial statements. However, under certain circumstances, this guidance could have an impact on the Company’s effective tax rate as changes between tax and book treatment of equity compensation will be recognized in the provision for income taxes beginning in Fiscal 2017. The Company currently estimates the adoption of this guidance will increase the effective tax rate by 1.1 percentage points in Fiscal 2017.

Business Combinations [Abstract]
Acquisitions	Acquisitions Nutri-Force On June 6, 2014, the Company acquired all of the outstanding equity interests of Nutri-Force. The total purchase price was $86.1 million in cash, which includes $5.0 million of contingent consideration which was paid in Fiscal 2015 . See Note 15. Segment and Product Data for additional information. The acquisition was funded by cash on hand. The results of operations of the acquired business are included in the Company’s results from the acquisition date. The Company has recorded its accounting for this acquisition in accordance with accounting guidance on business combinations. The acquisition resulted in goodwill primarily related to the expected benefits resulting from vertical integration as well as growth opportunities. The Company recorded $1.9 million and $4.0 million of acquisition and integration related costs during Fiscal 2015 and Fiscal 2014 , respectively, which are included in the consolidated statement of income within selling, general and administrative expenses. The purchase price of the acquisition has been allocated to the net tangible and intangible assets acquired, with the remainder recorded as goodwill on the basis of estimated fair values. The goodwill was allocated to the Company’s manufacturing segment. The allocation is as follows (in thousands): Consideration transferred $ 81,538 Working capital adjustment (487 ) Estimated contingent consideration 4,041 (a) Total consideration $ 85,092 Less: net identifiable assets acquired Current assets 33,798 Non-current assets 10,008 Intangible assets 18,800 Current liabilities (10,150 ) Total net identifiable assets acquired $ 52,456 Goodwill $ 32,636 (a) In the fourth quarter of Fiscal 2014 , the Company recorded approximately $1.0 million of additional contingent consideration, which is included in the consolidated statement of income within selling, general and administrative expenses. As a result of fair value accounting for the acquisition, current assets includes an inventory valuation step-up of $4.5 million , which was charged to cost of goods sold during Fiscal 2014 . Intangible assets consist of brands totaling $10.0 million , customer relationships of $7.5 million and internally-developed software of $1.3 million which are being amortized over their estimated useful lives of 18 years , 20 years and 5 years , respectively. The goodwill of $32.6 million is being amortized for tax purposes. From June 6, 2014 through December 27, 2014 , the acquired business generated net sales to third parties of $40.3 million and a pre-tax net loss of $1.8 million , excluding acquisition and integration costs. The pre-tax net loss includes the $4.5 million of charges related to the inventory valuation step-up noted above. The results represent the manufacturing segment. Pro forma results are not presented as the acquisition was not significant to the operating results for Fiscal 2016 , Fiscal 2015 or Fiscal 2014 .

Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is allocated between the Company’s segments (reporting units), retail, direct and manufacturing. The following table discloses the carrying value of all intangible assets (in thousands): December 31, 2016 December 26, 2015 Gross Carrying Amount Accumulated Amortization Impairment Charges Net Gross Carrying Amount Accumulated Amortization Net Intangible assets: Goodwill $ 243,269 $ — $ 32,636 $ 210,633 $ 243,269 $ — $ 243,269 Tradenames - Indefinite-lived 68,405 — — 68,405 68,405 — 68,405 Brands 10,000 1,435 — 8,565 10,000 880 9,120 Customer relationships 7,500 906 6,594 — 7,500 594 6,906 Tradenames - Definite-lived 4,964 3,073 — 1,891 4,673 2,722 1,951 Software 1,300 672 — 628 1,300 412 888 $ 335,438 $ 6,086 39,230 $ 290,122 $ 335,147 $ 4,608 $ 330,539 Intangible amortization expense for Fiscal 2016 , Fiscal 2015 and Fiscal 2014 was $1.5 million , $2.3 million and $1.7 million , respectively. The annual impairment tests for goodwill and tradenames were performed during the fourth quarter of Fiscal 2016 . In Fiscal 2016, the Company performed a quantitative analysis of its retail and direct reporting units and determined that the fair value of these reporting units was greater that their respective carrying values. As a result, the Company believes the fair values of each of these reporting units and indefinite-lived tradenames substantially exceeds their respective carrying values. Since the acquisition in Fiscal 2014, Nutri-Force, our manufacturing reporting unit, has experienced disruption in its ability to optimize production capacity, volatility in sales performance, loss of third party customers, and correspondingly has experienced lower service levels to customers. Based upon the operating results of Nutri-Force during the three months ended June 25, 2016, we concluded that an impairment trigger occurred for the manufacturing reporting unit and therefore an impairment test was performed. A discounted cash flow model was prepared using the internal forecast, including an estimate of long-term future growth rates and a discount rate determined by management to be commensurate with the risk inherent in this forecast. The results of this analysis determined the fair value of the manufacturing reporting unit exceeded its carrying value, and as a result, we concluded the goodwill assigned to the reporting unit was not impaired. However, the fair value of the manufacturing reporting unit exceeded its carrying value by approximately 5% , which was not considered to be a substantial excess over the carrying value. While financial results during the three months ended September 24, 2016 did not improve, we continued to closely monitor the financial performance of Nutri-Force. During the fiscal fourth quarter, the performance of Nutri-Force declined and expectations of future years were reduced significantly due to on-going churn in third party customers and its inability to reduce costs. In the fiscal fourth quarter, the Company performed its annual quantitative analysis of the manufacturing reporting unit as of October 22, 2016, based on the operating plan for Fiscal 2017, and then a subsequent analysis based on an updated long range projection due to further deterioration in operating results, which indicated that the carrying value of Nutri-Force exceeded its fair value. The Company proceeded to step two of the impairment analysis. Based on the results of these analyses, the Company recorded impairment charges of $32.6 million on goodwill and $6.6 million on the customer relationships intangible asset of Nutri-Force, which are included in selling, general and administrative expenses in the consolidated statement of income. There have been no impairment charges related to goodwill or other intangibles during Fiscal 2015 and Fiscal 2014 . The useful lives of the Company’s definite-lived intangible assets are between 3 to 18 years . The expected amortization expense on definite-lived intangible assets on the Company’s consolidated balance sheet at December 31, 2016 , is as follows (in thousands): Fiscal 2017 $ 1,073 Fiscal 2018 1,067 Fiscal 2019 915 Fiscal 2020 807 Fiscal 2021 807 Thereafter 6,415 $ 11,084

Debt Disclosure [Abstract]
Credit Arrangements	Credit Arrangements Convertible Senior Notes due 2020 On December 9, 2015 , the Company issued $143.8 million of its 2.25% Convertible Senior Notes due 2020 (the “Convertible Notes”). The Convertible Notes are senior unsecured obligations of VSI. Interest on the Convertible Notes is payable on June 1 and December 1 of each year, commencing on June 1, 2016 until their maturity date of December 1, 2020 . The Company may not redeem the Convertible Notes prior to the maturity date. Prior to July 1, 2020, the Convertible Notes will be convertible only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2016, if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of Convertible Notes for such trading day was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On or after July 1, 2020 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. The Convertible Notes will be convertible at an initial conversion rate of 25.1625 shares of the Company’s common stock per $1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $39.74 . The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, the Company is required to increase, in certain circumstances, the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event including customary conversion rate adjustments in connection with a “make-whole fundamental change” as defined. Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at its election. The Company allocated the principal amount of the Convertible Notes between its liability and equity components (see table below). The carrying amount of the liability component was determined by measuring the fair value of a similar debt instrument of similar credit quality and maturity that did not have the conversion feature. The carrying amount of the equity component, representing the embedded conversion option, was determined by deducting the fair value of the liability component from the principal amount of the Convertible Notes as a whole. The equity component was recorded to additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the Convertible Notes over the carrying amount of the liability component was recorded as a debt discount, and is being amortized to interest expense using an effective interest rate of 3.8% over the term of the Convertible Notes. The Company allocated the total amount of transaction costs incurred to the liability and equity components using the same proportions as the proceeds from the Convertible Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the liability component of the Convertible Notes, and are being amortized to interest expense using the effective interest method through the maturity date. Transaction costs attributable to the equity component were netted with the equity component of the Convertible Notes in additional paid-in capital. The Convertible Notes consist of the following components (in thousands): December 31, 2016 December 26, 2015 Liability component: Principal $ 143,750 $ 143,750 Conversion feature (24,800 ) (24,800 ) Liability portion of debt issuance costs (3,802 ) (3,800 ) Amortization 5,726 260 Net carrying amount $ 120,874 $ 115,410 Equity component: Conversion feature $ 24,800 $ 24,800 Equity portion of debt issuance costs (793 ) (793 ) Deferred taxes 941 941 Net carrying amount $ 24,948 $ 24,948 In connection with the issuance of the Convertible Notes, the Company entered into convertible note hedge transactions for which it paid an aggregate $26.4 million . In addition, the Company sold warrants for which it received aggregate proceeds of $13.0 million . The convertible note hedge transactions are expected generally to reduce potential dilution of the Company’s common stock upon any conversion of notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes. However, the warrant transaction could separately have a dilutive effect to the extent that the market value per share of the Company’s common stock exceeds the applicable strike price of the warrant transactions, which is approximately $52.99 at inception. As these transactions meet certain accounting criteria, the convertible note hedge and warrant transactions are recorded in stockholders’ equity, are not accounted for as derivatives and are not remeasured each reporting period. The net proceeds from the Convertible Notes and related transactions of $125.7 million , net of commissions and offering costs of $4.6 million , are being used to repurchase shares of the Company’s common stock under the Company’s share repurchase programs. Refer to Note 11. Share Repurchase Programs for additional information. Revolving Credit Facility As of December 31, 2016 and December 26, 2015 , the Company had $11.0 million and $8.0 million , respectively, of borrowings outstanding on its Revolving Credit Facility. Subject to the terms of the Revolving Credit Facility, which has a maturity date of October 11, 2018 , the Company may borrow up to $90.0 million , with a Company option to increase the facility up to a total of $150.0 million . The availability under the Revolving Credit Facility is subject to a borrowing base calculated on the value of certain accounts receivable as well as certain inventory of the Company. The obligations thereunder are secured by a security interest in substantially all of the assets of the Company. Under the Revolving Credit Facility, VSI has guaranteed the Company’s obligations, and Industries and its wholly-owned subsidiaries have each guaranteed the obligations of the other respective entities. The Revolving Credit Facility provides for affirmative and negative covenants affecting the Company. The Revolving Credit Facility restricts, among other things, the Company’s ability to incur indebtedness, create or permit liens on the Company’s assets, declare or pay dividends and make certain other restricted payments, consolidate, merge or recapitalize, sell assets, make certain investments, loans or other advances, enter into transactions with affiliates, change our line of business, and restricts the types of hedging activities the Company can enter into. The largest amount borrowed at any given point during Fiscal 2016 was $27.0 million . The unused available line of credit under the Revolving Credit Facility at December 31, 2016 was $76.1 million . Borrowings under the Revolving Credit Facility accrue interest, at the Company’s option, at the rate per annum based on an “alternative base rate” plus 0.25% or 0.50% or the adjusted Eurodollar rate plus 1.25% or 1.50% , in each case with the higher spread applicable in the event that the aggregate amount of the borrowings under the Revolving Credit Facility exceeds 50% of the borrowing base availability under the Revolving Credit Facility. The weighted average interest rate for the Revolving Credit facility for Fiscal 2016 was 1.78% . The commitment fee on the undrawn portion of the $90.0 million Revolving Credit Facility was 0.25% as of December 31, 2016 and December 26, 2015 . Interest expense, net for Fiscal 2016 , 2015 and 2014 consists of the following (in thousands): Fiscal Year Ended December 31, 2016 December 26, 2015 December 27, 2014 Amortization of debt discount on Convertible Notes $ 4,690 $ 223 $ — Interest on Convertible Notes 3,335 159 — Amortization of deferred financing fees 957 237 164 Interest / fees on the Revolving Credit Facility and other interest 541 487 344 Interest income — (1 ) (13 ) Interest expense, net $ 9,523 $ 1,105 $ 495

The temporary differences and carryforwards that give rise to deferred tax assets and liabilities at December 31, 2016 and December 26, 2015 are as follows (in thousands): December 31, 2016 December 26, 2015 Deferred tax assets: Net operating loss carryforward $ 2,535 $ 1,806 Deferred rent 10,775 11,389 Tenant allowance 3,938 4,215 Deferred sales 1,019 4,011 General accrued liabilities 7,132 6,790 Deferred wages and compensation 863 569 Inventory 7,443 7,205 Equity compensation expense 3,815 3,400 Debt 995 1,002 Other 2,735 3,299 41,250 43,686 Valuation allowance (2,535 ) (1,806 ) Deferred tax assets 38,715 41,880 Deferred tax liabilities: Trade name and goodwill (15,590 ) (29,777 ) Accumulated depreciation (4,589 ) (9,488 ) Prepaid expenses (1,689 ) (2,012 ) Deferred tax liabilities (21,868 ) (41,277 ) Net deferred tax asset $ 16,847 $ 603 The net deferred tax assets are included in other long-term assets on the consolidated balance sheets. Management periodically assesses whether the Company is more likely than not to realize some or all of its deferred tax assets. As of December 31, 2016 , with the exception of $2.5 million of deferred tax assets arising from a foreign and state net operating loss carryforward against which there is a valuation allowance (see above table), management determined that the Company is more likely than not to realize the deferred tax assets detailed above. Realization of deferred tax assets associated with the state net operating loss carryforwards is dependent upon generating sufficient taxable income prior to their expiration by tax jurisdiction. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state jurisdictions, Puerto Rico and Canada. The Company recognizes interest related to uncertain tax positions in income tax expense. The Company is no longer subject to U.S. federal examinations by tax authorities for years before 2014 and for state examinations before 2010. However, the tax authorities still have the ability to review the relevance of net operating loss carryforwards created in closed years if such tax attributes are utilized in open years (subsequent to 2010). The Company has domestic (U.S. state) and foreign net operating losses of approximately $8.2 million and $8.3 million at December 31, 2016 , against which a full valuation allowance is recorded. Domestic net operating losses generated will continue to expire annually through Fiscal 2032 . The Company’s foreign net operating loss is generated through operations in Canada, and will expire in Fiscal 2035 .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based Compensation	Stock Based Compensation Equity Incentive Plans - The Company has two equity incentive plans that provide stock based compensation to certain directors, officers, consultants and employees of the Company; the 2006 Stock Option Plan (the “2006 Plan”) and the Vitamin Shoppe 2009 Equity Incentive Plan amended and restated through April 2012 (the “2009 Plan”), under which the Company has granted stock options (includes non-qualified as well as performance based stock options), restricted shares (includes time based as well as performance based restricted shares), performance share units and restricted share units. The issuance of up to 7,453,678 shares of common stock is authorized under these plans. As of December 31, 2016 , there were 2,065,074 shares available to grant under both plans, which includes 161,185 shares currently held by the Company as treasury stock. Restricted shares, performance share units and restricted share units are issued at a value not less than the fair market value of the common shares on the date of the grant and stock options are exercisable at no less than the fair market value of the underlying shares on the date of grant. Equity awards of restricted shares generally shall become vested between two and three years subsequent to the date on which such equity grants were awarded. Performance share units shall become vested approximately three years subsequent to the date on which such equity grants were awarded. Stock options awarded shall become vested in three or four equal increments on each of the anniversaries of the date on which such equity grants were awarded and generally have a maximum term of 10 years . However, regarding performance based restricted shares, performance share units and performance based stock options, vesting is dependent not only on the passage of time, but also on the attainment of certain internal performance metrics. The vesting requirements for performance based restricted shares and performance based stock options permit a catch-up of vesting at the end of the vesting period. For accounting purposes, the expense for performance based stock options, performance based restricted shares and performance share units is calculated and recorded, based on the determination that the achievement of the pre-established performance targets are probable, over the relevant service period. Restricted share units generally shall become vested quarterly, or one year , subsequent to the date on which such equity grants were awarded. The following table summarizes restricted shares for the 2009 Plan as of December 31, 2016 and changes during Fiscal 2016 : Number of Unvested Restricted Shares Weighted Average Grant Date Fair Value Unvested at December 26, 2015 398,562 $ 42.65 Granted 181,712 $ 29.45 Vested (104,095 ) $ 46.87 Canceled/forfeited (103,362 ) $ 42.06 Unvested at December 31, 2016 372,817 $ 35.20 The total intrinsic value of restricted shares vested during Fiscal 2016 , Fiscal 2015 and Fiscal 2014 was $2.5 million , $6.3 million and $5.7 million , respectively. The following table summarizes stock options for the 2006 and 2009 Plans as of December 31, 2016 and changes during Fiscal 2016 : Number of Options Weighted Average Exercise Price Weighted Average Remaining Contractual Life (years) Aggregate Intrinsic Value (in thousands) Outstanding at December 26, 2015 284,838 $ 22.65 Granted 264,072 $ 29.21 Exercised (5,282 ) $ 17.11 Canceled/forfeited (40,831 ) $ 33.19 Outstanding at December 31, 2016 502,797 $ 25.30 5.39 $ 1,443 Vested or expected to vest at December 31, 2016 484,921 $ 25.30 5.39 — Vested and exercisable at December 31, 2016 256,797 $ 21.62 1.65 $ 1,422 The total intrinsic value of options exercised during Fiscal 2016 , Fiscal 2015 and Fiscal 2014 was $0.1 million , $1.0 million and $16.0 million , respectively. The cash received from options exercised during Fiscal 2016 , Fiscal 2015 and Fiscal 2014 was $0.1 million , $1.4 million and $9.4 million , respectively. The following table summarizes performance share units for the 2009 Plan as of December 31, 2016 and changes during Fiscal 2016: Number of Unvested Performance Share Units Weighted Average Grant Date Fair Value Unvested at December 26, 2015 — — Granted 134,927 $ 30.42 Vested — — Canceled/forfeited (9,912 ) $ 30.26 Unvested at December 31, 2016 125,015 $ 30.43 Performance share units granted during Fiscal 2016 shall become vested on December 29, 2018 if the performance criteria are achieved. Performance share units can vest at a range of 25% to 150% based on the achievement of pre-established performance targets. The following table summarizes restricted share units for the 2009 Plan as of December 31, 2016 and changes during Fiscal 2016 : Number of Unvested Restricted Share Units Weighted Average Grant Date Fair Value Unvested at December 26, 2015 11,280 $ 37.25 Granted 21,451 $ 30.68 Vested (17,341 ) $ 34.92 Canceled/forfeited — $ — Unvested at December 31, 2016 15,390 $ 30.71 The total intrinsic value of restricted share units vested during Fiscal 2016 , Fiscal 2015 and Fiscal 2014 was $0.4 million , $0.6 million and $0.3 million , respectively. Compensation expense attributable to stock-based compensation for Fiscal 2016 was $6.3 million , for Fiscal 2015 was $5.5 million and for Fiscal 2014 was $6.9 million . As of December 31, 2016 , the remaining unrecognized stock based compensation expense for non-vested stock options, restricted shares, performance share units and restricted share units to be expensed in future periods is $7.6 million , and the related weighted average period over which it is expected to be recognized is 1.7 years . Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates forfeitures based on its historical forfeiture rate since the inception of granting stock based awards. The estimated value of future forfeitures for stock options, restricted shares, performance share units and restricted share units as of December 31, 2016 is approximately $0.6 million . The weighted average grant date fair value of stock options was $7.96 and $18.99 for Fiscal 2016 and Fiscal 2014 , respectively. For Fiscal 2014, this valuation represents the fair value of subsequent annual tranches of performance based stock option grants. No stock options were granted in Fiscal 2015 . The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions: December 31, 2016 December 27, 2014 Expected dividend yield — % — % Weighted average expected volatility 32.4 % 35.3 % Weighted average risk-free interest rate 1.2 % 1.4 % Expected holding period(s) 4.00 years 4.00 - 4.43 years Treasury Stock — As part of the Company’s equity incentive plans, the Company makes required tax payments on behalf of employees as their restricted shares vest. The Company withholds the number of vested shares having a value on the date of vesting equal to the minimum statutory tax obligation. The shares withheld are recorded as treasury shares. During Fiscal 2016 , the Company purchased 41,051 shares in settlement of employees’ tax obligations for a total of $1.2 million . The Company accounts for treasury stock using the cost method. These shares are available to grant under the Company’s equity incentive plans.

Equity [Abstract]
Share Repurchase Programs	Share Repurchase Programs The Company’s board of directors approved share repurchase programs that enable the Company to purchase up to an aggregate of $300 million of its shares of common stock from time to time over three year periods ending on August 4, 2017 , May 5, 2018 and November 22, 2018 , respectively. As of December 31, 2016 , 8,064,325 shares have been repurchased for a total of $269.9 million . The repurchase program does not obligate the Company to acquire any specific number of shares of its common stock and may be suspended, terminated or modified at any time for any reason, including market conditions, the cost of repurchasing such shares, the availability of alternative investment opportunities, liquidity, and other factors deemed appropriate. These factors may also affect the timing and amount of share repurchases. During Fiscal 2016 and Fiscal 2015 , the Company repurchased 1,670,837 and 1,182,990 shares, respectively, of its common stock in the open market. The shares were retired upon repurchase. Open market share repurchases were $47.0 million in Fiscal 2016 and $44.2 million in Fiscal 2015 with average repurchase prices per share of $28.13 and $37.38 , respectively. In Fiscal 2016, the Company also repurchased 646,666 shares of its common stock for $19.0 million , or $29.40 per share, under a 10b5-1 program which the Company entered into to purchase shares under predetermined criteria. Additionally, the Company has entered into accelerated share repurchase (“ASR”) arrangements with financial institutions. In exchange for an up-front payment, the financial institutions initially deliver shares of the Company’s common stock. The total number of shares ultimately delivered, and therefore the average repurchase price paid per share, is determined at the end of the purchase period of each ASR based on the volume weighted-average price of the Company’s common stock during that period. The shares are retired in the periods they are delivered, and each up-front payment is accounted for as a reduction to stockholders’ equity in the Company’s Consolidated Balance Sheet in the period the payment was made. The Company reflects each ASR as a repurchase of common stock in the period delivered for purposes of calculating earnings per share and as a forward contract indexed to its own common stock. The ASRs met all of the applicable criteria for equity classification, and therefore, were not accounted for as derivative instruments. The following table summarizes the Company’s ASR arrangements: Beginning of ASR Period Up-front Payment (in millions) Initial Share Deliveries End of ASR Period Final Shares Delivered Average Repurchase Price November, 2014 $ 50.0 982,714 January, 2015 88,325 $ 46.68 December, 2015 $ 50.0 1,391,940 February, 2016 235,053 $ 30.73 In December 2015, the Company also repurchased 1,664,800 shares of its common stock for $51.9 million , or $31.17 per share, from purchasers of the Convertible Notes in privately negotiated transactions.

Segment Reporting [Abstract]
Segment and Product Data	Segment and Product Data The Company currently operates three business segments, retail, direct and manufacturing. The operating segments are segments of the Company for which separate financial information is available and for which operating results are evaluated regularly by executive management in deciding how to allocate resources and in assessing performance. The Company’s management evaluates segment operating results based on several indicators. The primary key performance indicators are sales and operating income for each segment. The table below represents key financial information for each of the Company’s business segments as well as corporate costs. The retail segment primarily includes the Company’s retail stores. The retail segment generates revenue primarily through the sale of VMS products through Vitamin Shoppe and Super Supplements retail stores in the United States and Puerto Rico. The direct segment generates revenue through the sale of VMS products primarily through the Company’s websites. The Company’s websites offer customers online access to a full assortment of approximately 17,000 SKUs. The manufacturing segment supplies the retail and direct segments, along with various thirds parties, with finished products for sale. Corporate costs represent all other expenses not allocated to the retail, direct or manufacturing segments which include, but are not limited to: human resources, legal, retail management, direct management, finance, information technology, depreciation (primarily related to assets utilized by the retail and direct business segments as well as corporate assets) and amortization, and various other corporate level activity related expenses. Intercompany sales transactions are eliminated in consolidation. The Company’s segments are designed to allocate resources internally and provide a framework to determine management responsibility. The Company has allocated $165.3 million and $45.3 million of its recorded goodwill to the retail and direct segments, respectively. The Company does not have identifiable assets separated by segment, with the exception of the identifiable assets of the manufacturing segment, which were $62.3 million and $88.4 million as of December 31, 2016 and December 26, 2015 , respectively.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value hierarchy requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, while Level 3 generally requires significant management judgment. The three levels are defined as follows: • Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities. • Level 2: Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets. • Level 3: Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability. The Company’s financial instruments include cash, accounts receivable, accounts payable and its Revolving Credit Facility. The Company believes that the recorded values of these financial instruments approximate their fair values due to their nature and respective durations. The Company's financial instruments also include its Convertible Notes (in thousands): December 31, 2016 December 26, 2015 Fair Value $ 111,563 $ 119,784 Carrying Value 120,874 115,410 The fair value of the Convertible Notes was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including the trading price of the Company’s Convertible Notes, when available, the Company’s stock price and interest rates based on similar debt issued by parties with credit ratings similar to the Company (Level 1 or 2). Certain assets are measured at fair value on a non-recurring basis, that is, the assets are subject to fair value adjustments in certain circumstances such as when there is evidence of impairment. These measures of fair value, and related inputs, are considered Level 2 or 3 measures under the fair value hierarchy.

Summary of Significant Accoun25

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates —The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents —Cash and cash equivalents include all highly liquid investments with original maturities of ninety days or less. The Company reclassifies cash overdrafts to accounts payable.
Accounts Receivable	Accounts Receivable —Through Nutri-Force, the Company sells product to third-party wholesale customers. The Company monitors the financial condition of its third-party wholesale customers and establishes an allowance for doubtful accounts for balances estimated to be uncollectible. In addition, customer allowances including promotional discounts and allowances are provided to wholesale customers based on various contract terms and are recorded as a reduction to revenue.
Inventories	Inventories —Inventories are stated at the lower of cost or market value. Cost is determined using the weighted average method. Finished goods inventory includes costs of freight on internally transferred merchandise, and costs associated with our buying department and distribution facilities, as well as manufacturing overhead which are capitalized into inventory and then expensed as merchandise is sold. In addition, the cost of inventory is reduced by purchase discounts and other allowances received from certain of our vendors. The Company estimates losses for expiring inventory and the net realizable value of inventory based on when a product is close to expiration and not expected to be sold, when a product has reached its expiration date, or when a product is not expected to be saleable. In determining the reserves for these products, consideration is given to such factors as the amount of inventory on hand, the remaining shelf life, current and expected market conditions, historical trends and the likelihood of recovering the inventory costs based on anticipated demand.
Property and Equipment, Net	Property and Equipment, Net —Property and equipment, net is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided for on a straight-line basis over the estimated useful lives of the related assets. Furniture, fixtures and equipment are generally depreciated over seven years . Leasehold improvements are amortized generally over the shorter of their useful lives or related lease terms. The direct internal and external costs associated with the development of the features and functionality of the Company’s website, transaction processing systems, telecommunications infrastructure and network operations, are capitalized and are amortized on a straight line basis over the estimated useful lives of generally five years . Capitalization of costs begins when the preliminary project stage is completed and management authorizes and commits to funding the computer software project and that it is probable that the project will be completed and the software will be used to perform the function intended. Depreciation of the assets commences when they are put into use. Expenditures for repairs and maintenance are expensed as incurred and expenditures for major renovations and improvements are capitalized. Upon retirement or disposition of property and equipment, the applicable cost and accumulated depreciation are removed from the accounts and any resulting gains or losses are included in the results of operations.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets —The Company reviews its long-lived assets for impairment whenever events or changes in circumstances, including store closures, indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset to undiscounted pre-tax future net cash flows expected to be generated by that asset. If the undiscounted future cash flows are not adequate to recover the carrying value of the asset, an impairment loss is recognized for the amount by which the carrying amount of the assets exceeds the fair value of the assets.
Goodwill and Other Intangibles	Goodwill and Other Intangibles —Goodwill and other indefinite-lived intangibles are not amortized. Evaluations for impairment are performed at least annually, in the fourth quarter of each year, or whenever impairment indicators exist. Goodwill is evaluated for impairment at the reporting unit level (the Company’s operating segments). The evaluation of goodwill and other indefinite-lived intangibles may first consider qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value is less than its carrying value. A quantitative evaluation is performed if the qualitative evaluation results in a more likely than not determination or if a qualitative evaluation is not performed. The Company’s quantitative impairment tests involve calculating the fair value of each reporting unit using the discounted cash flow analysis method along with the market multiples method which is used for additional validation of the fair value calculated. These valuation methods require certain assumptions and estimates be made by the Company regarding certain industry trends and future profitability. It is the Company’s policy to conduct goodwill impairment testing from information based on current business projections, which include projected future revenues and cash flows. The cash flows utilized in the discounted cash flow analysis are based on five-year financial forecasts developed internally by management. Cash flows for each reporting unit are discounted using an internally derived weighted average cost of capital which reflects the costs of borrowing for the funding of each unit as well as the risk associated with the units themselves. If the carrying amount of a reporting unit exceeds its fair value, the Company would compare the implied fair value of the reporting unit goodwill with its carrying value. To compute the implied fair value of goodwill, the Company would assign the fair value of the reporting unit to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. Also as part of the quantitative test, the Company conducts the test using a 10% decrease in its revenue projections as an additional sensitivity test to ensure the reporting unit’s fair value is greater than its carrying value should events in the future be less favorable than anticipated. For indefinite-lived tradenames, we utilize the royalty relief method in our quantitative evaluations. Under the royalty relief method, a royalty rate is determined based on comparable licensing arrangements which is applied to the revenue projections for the applicable indefinite-lived tradename and the fair value is calculated using a discounted cash flow analysis. To the extent that the implied fair value associated with the goodwill and indefinite-lived intangible assets is less than the recorded value, this would result in a write down of the carrying value of the asset. Impairment tests between annual tests may be undertaken if an event occurs or circumstances change that could reduce the fair value of a reporting unit below its carrying value. The valuation of the goodwill and indefinite-lived intangible assets is affected by, among other things, the Company’s projections for the future and estimated results of future operations. Changes in the business plan or operating results that are different than the estimates used to develop the valuation of the assets may impact these valuations. For those intangible assets which have definite lives, the Company amortizes their cost on a straight-line basis over their estimated useful lives, the periods of which vary based on their particular contractual terms. In Fiscal 2016, the Company performed a quantitative analysis of its retail and direct reporting units and determined that the fair value of these reporting units was greater that their respective carrying values. As a result, the Company believes the fair values of each of these reporting units and indefinite-lived tradenames substantially exceeds their respective carrying values. During Fiscal 2016, the Company also performed quantitative analyses of its manufacturing reporting unit and determined the carrying value of the manufacturing reporting unit exceeded its fair value, which resulted in the write-off of the corresponding goodwill of $32.6 million and the customer relationship intangible asset of $6.6 million . Refer to Note 5. Goodwill and Intangible Assets for additional information. There have been no impairment charges related to goodwill or other intangibles during Fiscal 2015 and Fiscal 2014 .
Rent Expenses, Deferred Rent and Landlord Construction Allowances	Rent Expenses, Deferred Rent and Landlord Construction Allowances —Rent expense and rent incentives, including landlord construction allowances, are recognized on a straight-line basis over the lease term. The Company records rent expense for stores, distribution centers and manufacturing facilities as a component of cost of goods sold. The Company accounts for landlord construction allowances as lease incentives and records them as a component of deferred rent, which is recognized in cost of goods sold over the lease term.
Revenue Recognition	Revenue Recognition —The Company recognizes revenue when merchandise is sold “at point of sale” in retail stores or upon delivery to a direct customer. In addition, shipping fees billed to customers are classified as sales. Amount recognized as shipping revenue during Fiscal 2016 , Fiscal 2015 and Fiscal 2014 , were $2.2 million , $2.0 million and $3.0 million respectively. Nutri-Force sells product primarily to third-party customers and to our retail and direct segments. Wholesale revenue is recognized when risk of loss, title and insurable risks have transferred to the customer, net of estimated returns and allowances. To arrive at net sales, gross sales are reduced by deferred sales, customer discounts, actual customer returns and a provision for estimated future customer returns, which is based on management’s review of historical and current customer returns. Sales taxes collected from customers are presented on a net basis and as such are excluded from revenue.
Cost of Goods Sold	Cost of Goods Sold —The Company includes the cost of inventory sold, costs of warehousing, distribution, manufacturing and store occupancy costs in cost of goods sold and excludes depreciation and amortization related to the retail and direct segments, which is included within selling, general and administrative expenses. Warehousing, distribution and manufacturing costs, which are capitalized into inventory and then expensed as merchandise is sold, include freight on internally transferred merchandise as well as for shipments to direct and wholesale customers and costs associated with our buying department and distribution facilities, as well as manufacturing overhead. Store occupancy costs include rent, common area maintenance, real estate taxes and utilities.
Vendor Allowances	Vendor Allowances —Vendor allowances include discounts, allowances and rebates received from vendors and are based on various contract terms. Vendor allowances are recognized as either purchase discounts which represent a reduction of product cost, funding which is capitalized into inventory and recognized in the statement of income as the merchandise is sold, or direct offset which represents funding subject to immediate recognition in the statement of income, depending on the nature of the allowance.
Frequent Buyer Program	Frequent Buyer Program —The Company has a frequent buyer program (“Healthy Awards Program”), whereby customers earn points toward free merchandise based on the dollar volume of purchases. Beginning in Fiscal 2016, points are earned each calendar quarter and must be redeemed within the subsequent calendar quarter or they expire. In previous years, points were earned each calendar year and must be redeemed within the first three months of the following year or they expire. Sales are deferred at the time points are earned based on the value of points that are projected to be redeemed, which are based on historical redemption data. The Company records a liability in the period points are earned with a corresponding reduction of sales.
Store Pre-opening Costs	Store Pre-opening Costs —Costs associated with the opening of new retail stores and start up activities are expensed as incurred.
Advertising Costs	Advertising Costs —The costs of advertising for online marketing arrangements, magazines, direct mail and radio are expensed as incurred, or the first time the advertising takes place. Advertising expense was $21.9 million , $21.6 million and $19.3 million for Fiscal 2016 , Fiscal 2015 and Fiscal 2014 , respectively.
Online Marketing Arrangements	Online Marketing Arrangements —The Company has entered into online marketing arrangements with various online companies. These agreements are established for periods of 24 months , 12 months or, in some cases, a lesser period and generally provide for compensation based on revenue sharing upon the attainment of stipulated revenue amounts, a percentage of the media expenditure managed by the online partner, or based on the number of visitors that the online company refers to the Company. The Company had no fixed payment commitments during Fiscal 2016 , Fiscal 2015 and Fiscal 2014 .
Income Taxes	Income Taxes —Deferred income tax assets and liabilities are recorded in accordance with the liability method. Deferred income taxes have been provided for temporary differences between the tax bases and financial reporting bases of the Company’s assets and liabilities using the tax rates and laws in effect for the periods in which the differences are expected to reverse. The Company accounts for tax positions based on the provisions of the accounting literature related to accounting for uncertainty in income tax positions. Such literature provides guidance for the recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For tax positions that are not more likely than not sustainable upon audit, the Company recognizes the largest amount of the benefit that is more likely than not to be sustained. The Company makes estimates of the potential liability based on our assessment of all potential tax exposures. In addition, the Company uses factors such as applicable tax laws and regulations, current information and past experience with similar issues to make these assessments. The tax positions are analyzed regularly and adjustments are made as events occur that warrant adjustments for those positions. The Company records interest expense and penalties payable to relevant tax authorities as income tax expense.
Concentrations of Credit Risk	Concentrations of Credit Risk —Financial instruments, which potentially subject the Company to concentrations of credit risk, include accounts receivable from wholesale customers as well as debit and credit card processors of retail transactions. As of December 31, 2016 and December 26, 2015 , five customers represented approximately 58% and 53% , respectively, of the accounts receivable from wholesale customers. Accounts receivable from debit and credit card processors, included in prepaid expenses and other current assets on the consolidated balance sheets, totaled $10.6 million at December 31, 2016 and $10.2 million at December 26, 2015 . The Company had one supplier from whom we purchased at least 5% of our merchandise during Fiscal 2016 , two suppliers from whom we purchased at least 5% of our merchandise during Fiscal 2015 and one supplier from whom we purchased at least 5% of our merchandise during Fiscal 2014 . We purchased approximately 11% of our total merchandise from these suppliers during Fiscal 2016 and approximately 17% during Fiscal 2015 and 12% during Fiscal 2014 . The Company is subject to concentrations of credit risk associated with cash and cash equivalents, and at times holds cash balances in excess of Federal Deposit Insurance Corporation limits.
Stock-Based Compensation	Stock-Based Compensation —Stock-based compensation cost is measured at the grant date based on the fair value of awards and is recognized as expense on a straight-line basis over the requisite service period for each separately vesting portion of the award, net of anticipated forfeitures. With the exception of restricted shares, performance share units and restricted share units, determining the fair value of stock-based awards at the grant date requires considerable judgment, including estimating expected volatility, expected term and risk-free rate. Compensation expense resulting from the granting of restricted shares, performance share units and restricted share units is based on the grant date fair value of those common shares and is recognized generally over the two to three year vesting period for restricted shares, the approximately three year vesting period for performance share units and over the quarterly or one year vesting periods for restricted share units. For accounting purposes, the expense for performance based stock options, performance based restricted shares and performance share units is calculated and recorded, based on the determination that the achievement of the pre-established performance targets are probable, over the relevant service period. The vesting requirements for performance based stock options and performance based restricted shares permit a catch-up of vesting at the end of the vesting period. Expense related to shares purchased under the Company’s Employee Stock Purchase Plan (“ESPP”) is accounted for based on fair value recognition requirements similar to stock options. ESPP participation occurs each calendar quarter (the “Participation Period”) and the expense of which is subject to employee participation in the plan. Under the ESPP, participating employees are allowed to purchase shares at 85% of the lower of the market price of the Company’s common stock at either the first or last trading day of the Participation Period. Compensation expense related to the ESPP is based on the estimated fair value of the discount and purchase price offered on the estimated shares to be purchased under the ESPP. Expense is calculated quarterly, based on the employee contributions made over the applicable three-month Participation Period, using volatility and risk free rates applicable to that three -month period.
Net Income Per Share	Net Income Per Share —The Company’s basic net income per share excludes the dilutive effect of stock options, unvested restricted shares, unvested performance share units and unvested restricted share units. It is based upon the weighted average number of common shares outstanding during the period divided into net income. Diluted net income per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. Stock options, unvested restricted shares, unvested performance share units, warrants and unvested restricted share units are included as potential dilutive securities for the periods applicable, using the treasury stock method to the extent dilutive.
Recent Accounting Pronouncements	Recent Accounting Pronouncements — Except as noted below, the Company has considered all new accounting pronouncements and has concluded that there are no new pronouncements that may have a material impact on its results of operations, financial condition, or cash flows, based on current information. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). Under ASU 2014-09, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of ASU 2014-09 by one year. ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017 for public companies and early adoption of ASU 2014-09 is permitted for public companies for annual reporting periods beginning after December 15, 2016. The Company currently expects this guidance will not have a material impact on the Company's consolidated financial statements. However, the Company is still evaluating ASU 2014-09 including the determination of the transition approach it will utilize. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), Leases (Topic 842). ASU 2016-02 was issued by the FASB to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. ASU 2016-02 will require modified retrospective application at the beginning of our first quarter of Fiscal 2019, but permits adoption in an earlier period. The Company currently expects this guidance will not have a material impact on the Company's results of operations. However, the Company is still evaluating ASU 2016-02 in order to determine the impact of this guidance on the Company’s balance sheet and anticipates this guidance will result in a significant increase to long-term assets and liabilities given we have a significant number of leases. In March 2016, the FASB issued Accounting Standards Update No. 2016-09 (“ASU 2016-09”), Compensation-Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 addresses simplification of several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of ASU 2016-09 is permitted. The Company has evaluated ASU 2016-09 and does not expect the impact of this guidance to have a material impact on the Company's consolidated financial statements. However, under certain circumstances, this guidance could have an impact on the Company’s effective tax rate as changes between tax and book treatment of equity compensation will be recognized in the provision for income taxes beginning in Fiscal 2017. The Company currently estimates the adoption of this guidance will increase the effective tax rate by 1.1 percentage points in Fiscal 2017.
