Nutrisystem is a commercial provider of weight loss products and services headquartered in Fort Washington, Pennsylvania. 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.[]

The company launched its mobile platorm in 2010. WebDiet, Inc., a Silicon Valley startup, accused Nutrisystem of stealing their technology, but the case was dismissed in May, 2014.[1][2][3]

In 2012, Dawn Zier joined Nutrisystem as CEO.[4]

As of 2014, there was tentative evidence that at three months that Nutrisystem resulted in 3.8% more weight loss than a control group, but no good evidence of any benefit in the longer term.[5]

In 2015, Nutrisystem acquired the South Beach Diet brand.[6] In December 2018, Tivity Health announced that it would acquire the Nutrisystem brand.[7] On October 19, 2020 Kainos Capital acquired the brand from Tivity Health.[8]

Ann Intern Med. 162 (7): 501-12. doi:10.7326/M14-2238. PMC 4446719. PMID 25844997. 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.
