Nutrisystem is a commercial provider of weight loss products and services headquartered in Fort Washington, Pennsylvania. Nutrisystem's initial product in 1972 was a liquid protein diet, but the company changed its offering after Slim-Fast came to prominence in that market.[1] The company originally offered weight loss counseling and products in brick and mortar centers, but in 1999, Nutrisystem moved to a direct-to-consumer business model, selling its products and programs on the Internet and by telephone.[2]

The company launched its mobile platform in 2010. WebDiet, Inc., a Silicon Valley startup, accused Nutrisystem of stealing their technology, but the case was dismissed in May, 2014.[3][4][5]

In 2012, Dawn Zier joined the firm as CEO.[6]

In 2015, thefirm acquired the South Beach Diet brand.[7] In December 2018, Tivity Health announced that it would acquire the Nutrisystem brand.[8] On October 19, 2020, Kainos Capital acquired the brand from Tivity Health.[9]

Efficacy and criticism

A systematic review in 2015 concluded that Nutrisystem "shows promise" because, in the short term, studies have shown that Nutrisystem was more effective at weight-loss than a control group, but found no studies of long-term efficacy. [10]

As of 2019, four weeks of a basic Nutrisystem plan costs the average American customer $274.99.[11] In light of this expense, the Mayo Clinic lists one of the disadvantages of the diet to be its potentially "prohibitive" cost.[12] Obesity specialist Fatima Cody Stanford writes that a potential disadvantage of the diet is that it complicates social eating because a person following the Nutrisystem plan has to follow a distinct dietary program.[11]

Nutrisystem demonstrates better short-term weight loss than control/education and behavioral counseling; however, we identified no long-term trial results. We conclude that Nutrisystem shows promise, but the lack of long-term RCTs prohibits definitive conclusions.
