         Interleukin Genetics Reports Second Quarter Financial Results

     WALTHAM, Mass.--(BUSINESS WIRE)--Aug. 10, 2004--Interleukin Genetics, Inc.
(OTCBB: ILGN) a leader in the development of personalized health products, today
reported revenue of $664,000 and a net loss of $921,000 or $0.04 per basic and
diluted share, for the quarter ended June 30, 2004.

     Key Milestone Achieved During Second Quarter of 2004:

     In June 2004, the Company signed a Research Agreement with Access Business
Group LLC (ABG), a subsidiary of Alticor Inc., to conduct research into the
development of a test to identify individuals with specific genetic variations
that affect how people gain and maintain weight. The agreement also includes
provisions to assist ABG in the development of nutritional products to help
manage weight in those individuals who are overweight but not obese, that is,
with a Body Mass Index (BMI) greater than 25 but less than 30. With the
execution of this agreement, Interleukin is eligible to receive up to $1.9
Million in additional research funding over a period of one year beginning on
July 1, 2004. The first phase of the agreement is a "proof of concept" with a
performance milestone that determines the continuance of the project.

     Financial Results:

     Revenue for the quarter was $664,000 compared to $633,000 in the same
quarter of 2003. Both periods include $625,000 in research funding related to
the research agreement with Alticor entered into in March 2003. For the quarter,
the Company reported a net loss of $921,000, or $0.04 per basic and diluted
share, as compared to a net loss of $948,000, or $0.04 per basic and diluted
share, for the same period last year.
     Research and development expenditures were $355,000 in the quarter ended
June 30, 2004 compared to $476,000 in the comparable quarterly period ended June
30, 2003. The decrease in R&D expenses reflects a re-allocation of internal
resources from internally-funded projects to the research project funded by
Alticor. Those reallocated costs are now reported as cost of revenue.
     Selling, general and administrative expenses were $749,000 for the quarter
ended June 30, 2004 compared to $603,000 during the same period last year. The
increase is primarily the result of the Company adding the appropriate
infrastructure in its efforts to develop other markets for its products and
building a CLIA laboratory.
     As of June 30, 2004, the Company reported total assets of $6,863,000,
including $5,473,000 in cash and cash equivalents as compared to total assets of
$5,458,000 including $4,759,000 in cash and cash equivalents as of December 31,
2003. Cash and cash equivalents as of March 31, 2004 were $6,495,000. The
increase in cash from December 31, 2003 reflects the $2,000,000 milestone
payment received from Alticor in March 2004.
     For the six months ended June 30, 2004, the Company reported revenue of
$1,309,000 and a net loss of $1,849,000 or $0.08 per share compared to revenue
of $662,000 and a net loss of $2,614,000 or $0.11 per share for the same period
last year.
