Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Presentation of Financial Statements The Company’s consolidated financial statements include 100% of the assets and liabilities of Nutrisystem, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Interim Financial Statements The Company’s consolidated financial statements included in this Quarterly Report on Form 10-Q are unaudited and, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the Company’s financial position and results of operations for these interim periods. Accordingly, readers of these consolidated financial statements should refer to the Company’s audited consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), and the related notes thereto, as of and for the year ended December 31, 2017, which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (the “2017 Annual Report”) as certain footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this report pursuant to the rules of the Securities and Exchange Commission (the “SEC”). The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the year ending December 31, 2018. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” (“ASU 2014-09”). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual periods beginning on or after December 15, 2017, including interim reporting periods within that reporting period and should be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized at the date of initial application. The Company has adopted the accounting standards codification (“ASC”) 606, “Revenue from Contracts with Customers,” on January 1, 2018 using the modified retrospective method by recognizing the cumulative effect as an adjustment to the opening balance of stockholders’ equity at January 1, 2018. Therefore, the comparative information for years ended prior to January 1, 2018 were not restated to comply with ASC 606. The Company applied the transition practical expedient to only assess contracts that were not completed contracts at the date of initial application when applying the cumulative effect method. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and footnote disclosures. The cumulative impact of adopting ASC 606 on January 1, 2018 was an increase in stockholders’ equity of $1,135. In February 2016, the FASB issued ASU No. 2016-02, “Leases,” which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating its population of leases and is continuing to assess all potential impacts of the standard, but currently believes the most significant impact relates to fulfillment warehouse agreements and its real estate operating lease. For the fulfillment warehouse agreements, the Company has identified the population and is currently assessing the impact. The Company does anticipate the recognition of additional assets and corresponding liabilities related to leases upon adoption but has not yet quantified these at this time. The Company plans to adopt the standard effective January 1, 2019 but has not yet selected a transition method. In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which clarifies and provides guidance on eight cash flow classification issues and is intended to reduce existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This standard is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this new accounting standard did not have a material impact on the Company’s consolidated financial statements and footnote disclosures. In May 2017, the FASB issued ASU No. 2017-09, “Scope of Modification Accounting,” which provides guidance about which changes to the terms or conditions of share-based payment awards require an entity to apply modification accounting. This standard is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this new accounting standard did not have a material impact on the Company’s consolidated financial statements and footnote disclosures. Cash, Cash equivalents include only securities having a maturity of three months or less at the time of purchase. At March 31, 2018 and December 31, 2017, demand accounts and money market funds comprised all of the Company’s cash and cash equivalents. Short term investments consist of investments in government and agency securities and corporate debt securities with original maturities between three months and three years. The Company classifies these investments as available-for-sale securities. These investments are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive loss, a component of stockholders’ equity, net of related tax effects. At March 31, 2018, cash, cash equivalents and short term investments consisted of the following: Gross Gross Unrealized Unrealized Estimated Cost Gains Losses Fair Value Cash $ 23,751 $ 0 $ 0 $ 23,751 Money market funds 308 0 0 308 Government and agency securities 46,197 156 (510 ) 45,843 Corporate debt securities 6,500 22 (68 ) 6,454 $ 76,756 $ 178 $ (578 ) $ 76,356 At December 31, 2017, cash, cash equivalents and short term investments consisted of the following: Gross Gross Unrealized Unrealized Estimated Cost Gains Losses Fair Value Cash $ 24,454 $ 0 $ 0 $ 24,454 Money market funds 200 0 0 200 Government and agency securities 42,220 135 (355 ) 42,000 Corporate debt securities 5,577 28 (37 ) 5,568 $ 72,451 $ 163 $ (392 ) $ 72,222 Fixed Assets Fixed assets are stated at cost. Depreciation expense is calculated using the straight-line method over the estimated useful lives of the related assets, which are generally two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the related lease term. Expenditures for repairs and maintenance are charged to expense as incurred, while major renewals and improvements are capitalized. Included in fixed assets is the capitalized cost of internal-use software and website development incurred during the application development stage. Capitalized costs are amortized using the straight-line method over the estimated useful life of the asset, which is generally two to five years. Costs incurred related to planning or maintenance of internal-use software and website development are charged to expense as incurred. The net book value of capitalized software was $15,923 and $16,419 at March 31, 2018 and December 31, 2017, respectively. Revenue Recognition On January 1, 2018, the Company adopted ASC 606 using the modified retrospective method by recognizing the cumulative effect as an adjustment to the opening balance of stockholders’ equity at January 1, 2018. While the adoption of this standard did not have a material impact on the Company’s consolidated financial statements and footnote disclosures it did have an impact on the timing of revenue recognized in accounting for gift cards as presented in the consolidated statement of operations for 2018. In accordance with the new standard, the Company is recognizing the estimated breakage of gift cards over the pattern of redemption of the gift cards. Prior to adopting ASC 606, the Company recognized gift card breakage when the likelihood of redemption became remote. The Company also is recognizing direct-mail advertising costs as expense as incurred. Prior to adopting ASC 606, the Company capitalized these costs and expensed over the period of benefit. Additionally, the Company is recognizing an asset for the carrying amount of product to be returned and for costs to obtain a contract if the amortization period is more than one year in duration. The Company is applying the practical expedient to expense costs to obtain a contract as incurred if the amortization period is less than one year. Prior to adopting ASC 606, the value of product expected to be returned was presented net as a reduction of the related reserve for returns and costs to obtain a contract were expensed as incurred. Revenue is measured based on the consideration specified in a contract with a customer and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product to a customer. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue producing transaction, that are collected by the Company from a customer, are excluded from revenue and presented on a net basis. Shipping and handling costs associated with outbound freight, after control over a product has transferred to a customer, are accounted for as a fulfillment cost and are included in revenue and cost of revenue in the accompanying consolidated statements of operations. Revenue from shipping and handling charges was $4,069 and $1,889 for the three months ended March 31, 2018 and 2017, respectively. The increase in shipping and handling was due primarily to an increased handling charge paid by the customer. The Company’s pre-packaged foods are sold directly to weight loss program participants primarily through the Internet and telephone, referred to as the direct channel, through QVC, a television shopping network, and select retailers. Pre-packaged foods are comprised of both frozen and non-frozen (ready-to-go) products. Products sold through the direct channel, both frozen and non-frozen, may be sold separately (a la carte) or as part of a packaged monthly meal plan for which customers pay for at the point of sale. Products sold through QVC are payable by QVC upon satisfaction of the performance obligation. Revenue is recognized at a point in time. Direct to consumer customers may return unopened ready-to-go products within 30 days of purchase in order to receive a refund or credit. Frozen products are nonreturnable and non-refundable unless the order is canceled within 14 days of delivery. The Company recognizes revenue at the shipping point. Products sold to retailers include both frozen and non-frozen products and are payable by the retailer upon satisfaction of the performance obligation. Revenue is recognized at a point in time. Certain retailers have the right to return unsold products. The Company recognizes revenue when the retailers take possession of the product. The Company accounts for the shipment of frozen and non-frozen products as separate performance obligations. The consideration, including variable consideration for product returns, are allocated between frozen and non-frozen products based on their stand-alone selling prices. The amount of revenue recognized is adjusted for expected returns, which are estimated based on historical data. In addition to its pre-packaged foods, the Company sells prepaid gift cards through a wholesaler that are redeemable through the Internet or telephone. Prepaid gift cards represent grants of rights to goods to be provided in the future to retail customers. The wholesaler has the right to return all unsold prepaid gift cards. The retail selling price of the gift cards is deferred in the balance sheets and recognized as revenue when the Company has satisfied its performance obligation when the retail customer redeems the gift card. The Company recognizes breakage amounts (estimated amount of unused gift cards) as revenue, in proportion to the actual gift card redemptions exercised by the retail customer in relation to the total expected redemptions of gift cards. The Company utilizes historical experience in estimating the total expected breakage and period over which the gift cards will be redeemed. In the following table, revenue is disaggregated by the source of revenue: Three Months Ended March 31, 2018 2017 Direct $ 193,953 $ 194,073 Retail 11,186 12,154 QVC 5,693 6,363 Other 98 87 $ 210,930 $ 212,677 The Company applied ASC 606 using the cumulative effect method and the comparative information for the prior year period has not been adjusted and continues to be reported under ASC 605. The following table provides information about receivables, contract assets and contract liabilities from contracts with customers: March 31, 2018 January 1, 2018 As Adjusted Receivables $ 21,592 $ 17,871 Contract assets $ 540 $ 279 Contract liabilities $ 12,280 $ 6,654 Receivables primarily relate to the timing of credit card receivables and sales to retailers. The contract assets primarily relate to unbilled accounts receivable and are included as other current assets in the accompanying consolidated balance sheet. The contract liabilities (deferred revenue) primarily relate to sale of prepaid gift cards and unshipped foods which are deferred until such time as the Company has satisfied its performance obligations. Significant changes in the contract liabilities (deferred revenue) balance during the period is as follows: Three Months Ended March 31, 2018 Revenue recognized that was included in the contract liability (def. revenue) balance at January 1, 2018 $ (3,755 ) Increases due to cash received for prepaid gift cards sold or unshipped food, excluding amounts recognized as revenue $ 9,381 The following table includes estimated revenue from the prepaid gift cards expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period: Remaining 2018 $ 9,018 2019 1,078 2020 28 $ 10,124 The Company applies the practical expedient in subtopic ASC 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less. The following table summarizes the impacts of adopting ASC 606 on the Company’s consolidated financials for 2018: Three Months Ended March 31, 2018 As Reported Adjustments Amounts without Adoption of ASC 606 Statement of Operations Revenue $ 210,930 $ 341 $ 210,589 Income tax benefit $ (646 ) $ (77 ) $ (569 ) Net income $ 2,803 $ 264 $ 2,539 March 31, 2018 As Reported Adjustments Amounts without Adoption of ASC 606 Balance Sheet ASSETS Prepaid income taxes $ 6,874 $ 409 $ 7,283 Prepaid expenses and other current assets $ 8,817 $ (490 ) $ 8,327 LIABILITIES Deferred revenue $ 12,280 $ (1,417 ) $ 13,697 Other accrued expenses and current liabilities $ 6,249 $ 99 $ 6,150 EQUITY Retained earnings $ 79,409 $ 1,399 $ 78,010 Three Months Ended March 31, 2018 As Reported Adjustments Amounts without Adoption of ASC 606 Statement of Cash Flows Net income $ 2,803 $ 264 $ 2,539 Changes in operating assets and liabilities: Prepaid expenses and other assets $ 3,085 $ (360 ) $ 3,445 Deferred revenue $ 5,626 $ (80 ) $ 5,706 Income taxes $ (389 ) $ 77 $ (466 ) Other accrued expenses and liabilities $ (185 ) $ 99 $ (284 ) The Company reviews the reserves for customer returns at each reporting period and adjusts them to reflect data available at that time. To estimate reserves for returns, the Company considers actual return rates in preceding periods and changes in product offerings or marketing methods that might impact returns going forward. To the extent the estimate of returns changes, the Company will adjust the reserve, which will impact the amount of revenue recognized in the period of the adjustment. The provision for estimated returns for the three months ended March 31, 2018 and 2017 was $5,798, and $6,432, respectively. The reserve for estimated returns incurred but not received and processed was $1,530 at March 31, 2018 and has been included in other accrued expenses and current liabilities in the accompanying consolidated balance sheets. At December 31, 2017, the reserve for estimated returns incurred but not received and processed was $868 and was recorded net of the carrying amount of product to be returned. Dependence on Suppliers Approximately 11%, 10% and 5%, respectively, of inventory purchases for the three months ended March 31, 2018 were from three suppliers. The Company has a supply arrangement with one of these suppliers that requires the Company to make minimum purchases. For the three months ended March 31, 2017, these suppliers supplied approximately 12%, 6% and 10%, respectively, of inventory purchases. The Company outsources 100% of its fulfillment operations to a third-party provider. Additionally, more than 97% of its direct to consumer orders are shipped by one third-party provider and more than 97% of its orders for the retail programs are shipped by another third-party provider. Fair Value of Financial Instruments A three-tier fair value hierarchy has been established by the FASB Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3—Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. The fair values of the Company’s Level 1 instruments are based on quoted prices in active exchange markets for identical assets. The Company had no Level 2 or 3 instruments at March 31, 2018 and December 31, 2017. The following table summarizes the Company’s financial assets measured at fair value at March 31, 2018: Total Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Money market funds $ 308 $ 308 Government and agency securities 45,843 45,843 Corporate debt securities 6,454 6,454 Total assets $ 52,605 $ 52,605 The following table summarizes the Company’s financial assets measured at fair value at December 31, 2017: Total Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Money market funds $ 200 $ 200 Government and agency securities 42,000 42,000 Corporate debt securities 5,568 5,568 Total assets $ 47,768 $ 47,768 Earnings Per Share The Company uses the two-class method to calculate earnings per share (“EPS”) as the unvested restricted stock issued under the Company’s equity incentive plans are participating shares with nonforfeitable rights to dividends. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the number of weighted average shares outstanding during the period. Undistributed losses are not allocated to unvested restricted stock as the restricted stockholders are not obligated to share in the losses. The following table sets forth the computation of basic and diluted EPS: Three Months Ended March 31, 2018 2017 Net income $ 2,803 $ 7,484 Net income allocated to unvested restricted stock (25 ) (74 ) Net income allocated to common shares $ 2,778 $ 7,410 Weighted average shares outstanding: Basic 29,833 29,558 Effect of dilutive securities 313 427 Diluted 30,146 29,985 Basic income per common share $ 0.09 $ 0.25 Diluted income per common share $ 0.09 $ 0.25 In the three months ended March 31, 2018 and 2017, common stock equivalents representing 226 and 159 shares of common stock, respectively, were excluded from weighted average shares outstanding for diluted income per common share purposes because the effect would be anti-dilutive or the minimum performance requirements for such common stock equivalents have not yet been met. Cash Flow Information The Company made payments for income taxes of $25 and $4 in the three months ended March 31, 2018 and 2017, respectively. Interest payments in the three months ended March 31, 2018 and 2017 were $50 and $45, respectively. For the three months ended March 31, 2018 and 2017, the Company had non-cash capital additions of $535 and $793, respectively, of unpaid invoices in accounts payable and other accrued expenses and current liabilities. Use of Estimates The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and operating expenses during the reporting period. Actual results could differ from these estimates .

Intangible Assets Net Excluding Goodwill [Abstract]
Intangible Assets	3. INTANGIBLE ASSETS On December 17, 2015, the Company acquired the South Beach Diet (“SBD”) brand for a cash payment of $15,000. The acquisition was financed with existing cash. The Company developed the South Beach Diet® meal programs, products, and services in 2016 and launched a structured meal delivery weight-loss program as a distinct brand in 2017. The acquisition provides consumers with additional choices and enables the Company the ability to capture a greater share of the commercial weight loss market as it further leverages its expertise in product development, marketing, ecommerce, supply chain logistics and retail. The allocation of the purchase price was to the SBD trade name and is being amortized on a straight-line basis over a period of 15 years. The fair value measurement method used to measure the assets acquired utilized a number of significant unobservable inputs or Level 3 assumptions. These assumptions included, among others, projections of the acquired business’ future operating results, the implied fair value of assets using an income approach by preparing a discounted cash flow analysis and other subjective assumptions. The following table summarizes the Company’s identifiable intangible assets: March 31, 2018 December 31, 2017 Gross Net Gross Net Carrying Accumulated Carrying Carrying Accumulated Carrying Amount Amortization Amount Amount Amortization Amount Trade name $ 15,000 $ (2,250 ) $ 12,750 $ 15,000 $ (2,000 ) $ 13,000 Amortization expense for intangible assets was $250 in each of the three months ended March 31, 2018 and 2017. Estimated amortization expense for the next five years is expected to be as follows: Remaining 2018 $ 750 2019 1,000 2020 1,000 2021 1,000 2022 1,000 Additionally, the Company has $84 of domain names acquired in previous years with indefinite lives that are not being amortized.

Line Of Credit Facility [Abstract]
Credit Facility	4. CREDIT FACILITY On November 6, 2015, the Company entered into an Amended and Restated Credit Agreement that provides for a $50,000 unsecured revolving credit facility (the “Credit Facility”) with a lender. The Credit Facility can be drawn upon through November 6, 2020, at which time all amounts must be repaid. There were no borrowings outstanding at March 31, 2018 or December 31, 2017. The Credit Facility provides for interest at either a base rate or a LIBOR rate, in each case plus an applicable margin. The base rate will be the highest of (i) the Administrative Agent’s prime rate, (ii) 0.50% above the Federal Funds Rate and (iii) the LIBOR rate for deposits in dollars for a one-month interest period as determined three business days prior to such date, plus 1.50%. The LIBOR rate is equal to the London Inter-Bank Offered Rate for the relevant term. The applicable margin is subject to adjustment based on the Company’s consolidated fixed charge coverage ratio and ranges from 0.00-0.50% per year for base rate loans and from 1.25-1.75% per year for LIBOR rate loans. The Company also pays an unused line fee. The unused line fee is 0.25% of the total available credit. During each of the three months ended March 31, 2018 and 2017, the Company incurred no interest expense and $31 in an unused line fee under the Credit Facility. Interest payments and unused line fees are classified within interest income, net in the accompanying consolidated statements of operations. The Credit Facility contains financial and other covenants including a minimum consolidated fixed charge coverage ratio (applicable if there are outstanding borrowings), and limitations on, among other things, liens, indebtedness, certain acquisitions, consolidations and sales of assets. As of March 31, 2018, the Company was in compliance with all covenants contained in the Credit Facility. At March 31, 2018, the Company had $12 of unamortized debt issuance costs associated with the Credit Facility that are being amortized over its remaining term.

Stockholders' Equity	5. STOCKHOLDERS’ EQUITY Common Stock The Company issued 76 and 93 shares of common stock upon the exercise of stock options in the three months ended March 31, 2018 and 2017, respectively, and received proceeds of $1,484 and $1,803, respectively. During the three months ended March 31, 2018 and 2017, employees surrendered to the Company 40 and 29 shares of common stock, respectively, valued at $1,908 and $1,330, respectively, in satisfaction of tax withholding obligations associated with the vesting of equity awards. These shares are included in treasury stock. Additionally, during the three months ended March 31, 2017 employees surrendered to the Company 22 shares of common stock valued at $785 also in satisfaction of tax withholding obligations, which were retired. During the three months ended March 31, 2018 and 2017, the Company paid a dividend of $0.25 and $0.175 per share, respectively, to all stockholders of record. Subsequent to March 31, 2018, the Company’s Board of Directors declared a quarterly dividend of $0.25 per share payable on May 21, 2018 to stockholders of record as of May 10, 2018. The Company had a share repurchase program to repurchase up to $50,000 of its outstanding shares of common stock that expired on November 3, 2017. On October 25, 2017, the Company announced that its Board of Directors had authorized a new share repurchase program to replace the expiring program. Under the terms of the new share repurchase program, the Company may repurchase up to $50,000 of its outstanding shares of common stock over a 24-month period commencing November 4, 2017. The timing, number and amount of any shares repurchased will be determined by the Company at its discretion and will be based on a number of factors including its evaluation of general market and economic conditions, the trading price of the common stock, regulatory requirements and compliance with the terms of the Company’s outstanding indebtedness. The share repurchase program may be suspended or discontinued at any time without prior notice. During the three months ended March 31, 2018, the Company purchased and placed in treasury 319 shares of common stock under this program for an aggregate cost of $9,996. No shares were repurchased under the expired share repurchase program during the three months ended March 31, 2017. During April 2018, the Company purchased and placed in treasury an additional 130 shares of common stock for an aggregate cost of $5,000. Preferred Stock The Company has authorized 5,000 shares of preferred stock issuable in series upon resolution of the Board of Directors. Unless otherwise required by law, the Board of Directors can, without stockholder approval, issue preferred stock in the future with voting and conversion rights that could adversely affect the voting power of the common stock. The issuance of preferred stock may have the effect of delaying, averting or preventing a change in control of the Company.

The total intrinsic value of stock options exercised during the three months ended March 31, 2018 and 2017 was $2,082 and $1,893, respectively. The Company has issued restricted stock to employees generally with vesting terms ranging from two to four years. The fair value is equal to the market price of the Company’s common stock on the date of grant. Expense for restricted stock is amortized ratably over the vesting period. The following table summarizes the restricted stock activity for the three months ended March 31, 2018: Number of Shares Weighted-Average Grant-Date Fair Value Aggregate Intrinsic Value Nonvested, January 1, 2018 232 $ 32.96 Granted 115 52.67 Vested (112 ) 25.35 Forfeited 0 0 Nonvested, March 31, 2018 235 $ 46.24 $ 6,349 Additionally, the Company grants performance-based restricted stock units. The performance-based units have performance conditions and service-based vesting conditions. Each vesting tranche is treated as an individual award and the compensation expense is recognized on a straight-line basis over the requisite service period for each tranche. The requisite service period is a combination of the performance period and the subsequent vesting period based on continued service. The level of achievement of such goals may cause the actual amount of units that ultimately vest to range from 0% to 200% of the original units granted. The Company recognizes expense ratably over the vesting period for performance-based restricted stock units when it is probable that the performance criteria specified will be achieved. The fair value is equal to the market price of the Company’s common stock on the date of grant. The following table summarizes the restricted stock unit activity for the three months ended March 31, 2018: Number of Restricted Stock Units Weighted-Average Grant-Date Fair Value Aggregate Intrinsic Value Nonvested, January 1, 2018 232 $ 29.20 Granted 83 31.30 Vested 0 0 Forfeited 0 0 Nonvested, March 31, 2018 315 $ 29.75 $ 8,488 The Company recorded compensation expense of $1,980 and $2,055 in the accompanying consolidated statements of operations for the three months ended March 31, 2018 and 2017, respectively, in connection with the issuance of the restricted stock and restricted stock units. As of March 31, 2018, the Company expects 231 shares of restricted stock and 310 restricted stock units to vest. As of March 31, 2018, there was $14,298 of total unrecognized compensation expense related to unvested share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.1 years. The total unrecognized compensation expense will be fully charged to expense through the first quarter of 2021.

Commitments and Contingencies	7. COMMITMENTS AND CONTINGENCIES Litigation The Company is involved in various claims and routine litigation matters that arise in the ordinary course of business. In the opinion of management, after consultation with legal counsel, the outcomes of such matters are not anticipated to have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows in future years and management believes the range of reasonably possible losses from current matters is immaterial Contractual Commitments The Company’s principal commitments consisted of obligations under agreements with food suppliers, an agreement with its outside fulfillment provider, agreements with its Internet and networking providers, operating leases and employment contracts. These agreements may provide for annual pricing, annual purchase obligations, exclusivity in the production of certain products, as well as rebates if certain volume thresholds are exceeded, with terms of one to twelve years for operating leases and five years or less for the other agreements. The Company anticipates it will meet all annual purchase obligations in 2018.

Income Tax Disclosure [Abstract]
Income Taxes	8. INCOME TAXES On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cut and Jobs Act (the “Tax Act”). The Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018. Other changes include the acceleration of depreciation for certain assets placed into service after September 27, 2017 as well as, prospective changes beginning in 2018 including additional limitations on executive compensation. The Company recorded income taxes at an estimated effective income tax rate applied to income before income tax expense of 22.5% and 35.5% for the three months ended March 31, 2018 and 2017, respectively, which was reduced to (29.9)% and 20.6%, respectively, after recording discrete items, due primarily to the excess tax benefit from share based compensation. The Company recognized an excess tax benefit from share-based compensation of $799 and $1,382 in the three months ended March 31, 2018 and 2017, respectively, within income tax (benefit) expense in the accompanying consolidated statements of operations. Additionally, in the three months ended March 31, 2018, the Company recorded a tax benefit of $332 for the reduction of a valuation allowance due to changes in state tax legislation. The Company offsets taxable income for state tax purposes with net operating loss carryforwards. At December 31, 2017, the Company had net operating loss carryforwards of approximately $27,948 for state tax purposes. For state tax purposes, there is a limitation on the amount of net operating loss carryforwards that can be utilized in a given year to offset state taxable income and management believes that some of the net operating loss carryforwards will be subject to this annual limit in 2018. State net operating loss carryforwards will begin to expire in 2025. The total amount of gross unrecognized tax benefits as of March 31, 2018 and December 31, 2017 was $138 and $131, respectively. The total amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate is approximately $109 and $103 as of March 31, 2018 and December 31, 2017, respectively.

SUMMARY OF SIGNIFICANT ACCOUN17

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Presentation of Financial Statements	Presentation of Financial Statements The Company’s consolidated financial statements include 100% of the assets and liabilities of Nutrisystem, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Interim Financial Statements	Interim Financial Statements The Company’s consolidated financial statements included in this Quarterly Report on Form 10-Q are unaudited and, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the Company’s financial position and results of operations for these interim periods. Accordingly, readers of these consolidated financial statements should refer to the Company’s audited consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), and the related notes thereto, as of and for the year ended December 31, 2017, which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (the “2017 Annual Report”) as certain footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this report pursuant to the rules of the Securities and Exchange Commission (the “SEC”). The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the year ending December 31, 2018.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” (“ASU 2014-09”). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual periods beginning on or after December 15, 2017, including interim reporting periods within that reporting period and should be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized at the date of initial application. The Company has adopted the accounting standards codification (“ASC”) 606, “Revenue from Contracts with Customers,” on January 1, 2018 using the modified retrospective method by recognizing the cumulative effect as an adjustment to the opening balance of stockholders’ equity at January 1, 2018. Therefore, the comparative information for years ended prior to January 1, 2018 were not restated to comply with ASC 606. The Company applied the transition practical expedient to only assess contracts that were not completed contracts at the date of initial application when applying the cumulative effect method. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and footnote disclosures. The cumulative impact of adopting ASC 606 on January 1, 2018 was an increase in stockholders’ equity of $1,135. In February 2016, the FASB issued ASU No. 2016-02, “Leases,” which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating its population of leases and is continuing to assess all potential impacts of the standard, but currently believes the most significant impact relates to fulfillment warehouse agreements and its real estate operating lease. For the fulfillment warehouse agreements, the Company has identified the population and is currently assessing the impact. The Company does anticipate the recognition of additional assets and corresponding liabilities related to leases upon adoption but has not yet quantified these at this time. The Company plans to adopt the standard effective January 1, 2019 but has not yet selected a transition method. In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which clarifies and provides guidance on eight cash flow classification issues and is intended to reduce existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This standard is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this new accounting standard did not have a material impact on the Company’s consolidated financial statements and footnote disclosures. In May 2017, the FASB issued ASU No. 2017-09, “Scope of Modification Accounting,” which provides guidance about which changes to the terms or conditions of share-based payment awards require an entity to apply modification accounting. This standard is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this new accounting standard did not have a material impact on the Company’s consolidated financial statements and footnote disclosures.
Cash, Cash Equivalents and Short Term Investments	Cash, Cash equivalents include only securities having a maturity of three months or less at the time of purchase. At March 31, 2018 and December 31, 2017, demand accounts and money market funds comprised all of the Company’s cash and cash equivalents. Short term investments consist of investments in government and agency securities and corporate debt securities with original maturities between three months and three years. The Company classifies these investments as available-for-sale securities. These investments are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive loss, a component of stockholders’ equity, net of related tax effects. At March 31, 2018, cash, cash equivalents and short term investments consisted of the following: Gross Gross Unrealized Unrealized Estimated Cost Gains Losses Fair Value Cash $ 23,751 $ 0 $ 0 $ 23,751 Money market funds 308 0 0 308 Government and agency securities 46,197 156 (510 ) 45,843 Corporate debt securities 6,500 22 (68 ) 6,454 $ 76,756 $ 178 $ (578 ) $ 76,356 At December 31, 2017, cash, cash equivalents and short term investments consisted of the following: Gross Gross Unrealized Unrealized Estimated Cost Gains Losses Fair Value Cash $ 24,454 $ 0 $ 0 $ 24,454 Money market funds 200 0 0 200 Government and agency securities 42,220 135 (355 ) 42,000 Corporate debt securities 5,577 28 (37 ) 5,568 $ 72,451 $ 163 $ (392 ) $ 72,222
Fixed Assets	Fixed Assets Fixed assets are stated at cost. Depreciation expense is calculated using the straight-line method over the estimated useful lives of the related assets, which are generally two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the related lease term. Expenditures for repairs and maintenance are charged to expense as incurred, while major renewals and improvements are capitalized. Included in fixed assets is the capitalized cost of internal-use software and website development incurred during the application development stage. Capitalized costs are amortized using the straight-line method over the estimated useful life of the asset, which is generally two to five years. Costs incurred related to planning or maintenance of internal-use software and website development are charged to expense as incurred. The net book value of capitalized software was $15,923 and $16,419 at March 31, 2018 and December 31, 2017, respectively.
Revenue Recognition	Revenue Recognition On January 1, 2018, the Company adopted ASC 606 using the modified retrospective method by recognizing the cumulative effect as an adjustment to the opening balance of stockholders’ equity at January 1, 2018. While the adoption of this standard did not have a material impact on the Company’s consolidated financial statements and footnote disclosures it did have an impact on the timing of revenue recognized in accounting for gift cards as presented in the consolidated statement of operations for 2018. In accordance with the new standard, the Company is recognizing the estimated breakage of gift cards over the pattern of redemption of the gift cards. Prior to adopting ASC 606, the Company recognized gift card breakage when the likelihood of redemption became remote. The Company also is recognizing direct-mail advertising costs as expense as incurred. Prior to adopting ASC 606, the Company capitalized these costs and expensed over the period of benefit. Additionally, the Company is recognizing an asset for the carrying amount of product to be returned and for costs to obtain a contract if the amortization period is more than one year in duration. The Company is applying the practical expedient to expense costs to obtain a contract as incurred if the amortization period is less than one year. Prior to adopting ASC 606, the value of product expected to be returned was presented net as a reduction of the related reserve for returns and costs to obtain a contract were expensed as incurred. Revenue is measured based on the consideration specified in a contract with a customer and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product to a customer. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue producing transaction, that are collected by the Company from a customer, are excluded from revenue and presented on a net basis. Shipping and handling costs associated with outbound freight, after control over a product has transferred to a customer, are accounted for as a fulfillment cost and are included in revenue and cost of revenue in the accompanying consolidated statements of operations. Revenue from shipping and handling charges was $4,069 and $1,889 for the three months ended March 31, 2018 and 2017, respectively. The increase in shipping and handling was due primarily to an increased handling charge paid by the customer. The Company’s pre-packaged foods are sold directly to weight loss program participants primarily through the Internet and telephone, referred to as the direct channel, through QVC, a television shopping network, and select retailers. Pre-packaged foods are comprised of both frozen and non-frozen (ready-to-go) products. Products sold through the direct channel, both frozen and non-frozen, may be sold separately (a la carte) or as part of a packaged monthly meal plan for which customers pay for at the point of sale. Products sold through QVC are payable by QVC upon satisfaction of the performance obligation. Revenue is recognized at a point in time. Direct to consumer customers may return unopened ready-to-go products within 30 days of purchase in order to receive a refund or credit. Frozen products are nonreturnable and non-refundable unless the order is canceled within 14 days of delivery. The Company recognizes revenue at the shipping point. Products sold to retailers include both frozen and non-frozen products and are payable by the retailer upon satisfaction of the performance obligation. Revenue is recognized at a point in time. Certain retailers have the right to return unsold products. The Company recognizes revenue when the retailers take possession of the product. The Company accounts for the shipment of frozen and non-frozen products as separate performance obligations. The consideration, including variable consideration for product returns, are allocated between frozen and non-frozen products based on their stand-alone selling prices. The amount of revenue recognized is adjusted for expected returns, which are estimated based on historical data. In addition to its pre-packaged foods, the Company sells prepaid gift cards through a wholesaler that are redeemable through the Internet or telephone. Prepaid gift cards represent grants of rights to goods to be provided in the future to retail customers. The wholesaler has the right to return all unsold prepaid gift cards. The retail selling price of the gift cards is deferred in the balance sheets and recognized as revenue when the Company has satisfied its performance obligation when the retail customer redeems the gift card. The Company recognizes breakage amounts (estimated amount of unused gift cards) as revenue, in proportion to the actual gift card redemptions exercised by the retail customer in relation to the total expected redemptions of gift cards. The Company utilizes historical experience in estimating the total expected breakage and period over which the gift cards will be redeemed. In the following table, revenue is disaggregated by the source of revenue: Three Months Ended March 31, 2018 2017 Direct $ 193,953 $ 194,073 Retail 11,186 12,154 QVC 5,693 6,363 Other 98 87 $ 210,930 $ 212,677 The Company applied ASC 606 using the cumulative effect method and the comparative information for the prior year period has not been adjusted and continues to be reported under ASC 605. The following table provides information about receivables, contract assets and contract liabilities from contracts with customers: March 31, 2018 January 1, 2018 As Adjusted Receivables $ 21,592 $ 17,871 Contract assets $ 540 $ 279 Contract liabilities $ 12,280 $ 6,654 Receivables primarily relate to the timing of credit card receivables and sales to retailers.

To estimate reserves for returns, the Company considers actual return rates in preceding periods and changes in product offerings or marketing methods that might impact returns going forward. To the extent the estimate of returns changes, the Company will adjust the reserve, which will impact the amount of revenue recognized in the period of the adjustment. The provision for estimated returns for the three months ended March 31, 2018 and 2017 was $5,798, and $6,432, respectively. The reserve for estimated returns incurred but not received and processed was $1,530 at March 31, 2018 and has been included in other accrued expenses and current liabilities in the accompanying consolidated balance sheets. At December 31, 2017, the reserve for estimated returns incurred but not received and processed was $868 and was recorded net of the carrying amount of product to be returned.
Dependence on Suppliers	Dependence on Suppliers Approximately 11%, 10% and 5%, respectively, of inventory purchases for the three months ended March 31, 2018 were from three suppliers. The Company has a supply arrangement with one of these suppliers that requires the Company to make minimum purchases. For the three months ended March 31, 2017, these suppliers supplied approximately 12%, 6% and 10%, respectively, of inventory purchases. The Company outsources 100% of its fulfillment operations to a third-party provider. Additionally, more than 97% of its direct to consumer orders are shipped by one third-party provider and more than 97% of its orders for the retail programs are shipped by another third-party provider.
Fair Value of Financial Instruments	Fair Value of Financial Instruments A three-tier fair value hierarchy has been established by the FASB Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3—Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. The fair values of the Company’s Level 1 instruments are based on quoted prices in active exchange markets for identical assets. The Company had no Level 2 or 3 instruments at March 31, 2018 and December 31, 2017. The following table summarizes the Company’s financial assets measured at fair value at March 31, 2018: Total Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Money market funds $ 308 $ 308 Government and agency securities 45,843 45,843 Corporate debt securities 6,454 6,454 Total assets $ 52,605 $ 52,605 The following table summarizes the Company’s financial assets measured at fair value at December 31, 2017: Total Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Money market funds $ 200 $ 200 Government and agency securities 42,000 42,000 Corporate debt securities 5,568 5,568 Total assets $ 47,768 $ 47,768
Earnings Per Share	Earnings Per Share The Company uses the two-class method to calculate earnings per share (“EPS”) as the unvested restricted stock issued under the Company’s equity incentive plans are participating shares with nonforfeitable rights to dividends. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the number of weighted average shares outstanding during the period. Undistributed losses are not allocated to unvested restricted stock as the restricted stockholders are not obligated to share in the losses. The following table sets forth the computation of basic and diluted EPS: Three Months Ended March 31, 2018 2017 Net income $ 2,803 $ 7,484 Net income allocated to unvested restricted stock (25 ) (74 ) Net income allocated to common shares $ 2,778 $ 7,410 Weighted average shares outstanding: Basic 29,833 29,558 Effect of dilutive securities 313 427 Diluted 30,146 29,985 Basic income per common share $ 0.09 $ 0.25 Diluted income per common share $ 0.09 $ 0.25 In the three months ended March 31, 2018 and 2017, common stock equivalents representing 226 and 159 shares of common stock, respectively, were excluded from weighted average shares outstanding for diluted income per common share purposes because the effect would be anti-dilutive or the minimum performance requirements for such common stock equivalents have not yet been met.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and operating expenses during the reporting period. Actual results could differ from these estimates .
