NutriSystem
Definition
NutriSystem is a commercial weight loss program
based in the Philadelphia area that delivers heat-and-
eat foods directly to the customer’s home in 28-day
packages. Its products have been described as ‘‘fast
food for weight loss.’’ Customers select one of six
specialized subprograms, each of which offers a pre-
packaged assortment of food items called ‘‘Favorites
Package’’ or a completely customized selection. As of
2007 NutriSystem has about 800,000 customers in the
United States and Canada. In addition to its meal
delivery programs, the company offersdietary supple-
ments, including a multivitamin called Nutrihance. It
has also recently formed a business partnership with a
network of franchised fitness centers called Slim and
Tone. In early 2007, NutriSystem combined its direct
online marketing of diet foods with its network divi-
sion of franchised consultants. The company’s market
value was estimated at $2 billion as of early 2007.

Origins
NutriSystem began in 1972 as a producer of a
liquidproteindiet, which it abandoned in 1978 as a
result of competition from Slim-Fast, Carnation
weight loss products, and other over-the-counter
liquid diet drinks. NutriSystem then started a chain
of 1,200 bricks-and-mortar weight loss centers roughly
similar toWeight Watchers; dieters came to the cen-
ters in person to weigh in and then purchased prepack-
aged portion-controlled meals to take home. The
company went bankrupt in the early 1990s but rein-
vented itself in 1999 as an online meal delivery service.
As of the early 2000s, customers may order their
monthly food assortments by telephone as well as
online. Although a free weight loss counseling service
is available by telephone or online chat, fewer than
20% of customers make use of it.
NutriSystem conducted a survey in 2005 to gather
information about customer demographics, in the
course of which the company discovered that most of
its customers were women between the ages of 20 and


  1. In 2006 it began to target men as customers, using
    endorsements from such well-known professional ath-
    letes as John Kruk, Don Shula, and Dan Martino. Of
