Nutrisystem, headquartered in Fort Washington, Pennsylvania, is a commercial provider of weight loss products and services. Initially, the company offered weight loss counseling and products in brick and mortar centers. In 1999, the company moved to a direct-to-consumer business model, selling its products and programs over the Internet and through a company 800 number. Nutrisystems programs have been sold on the QVC television home shopping network since 2001 and in Costco stores since 2009. The company states that its mission is to provide a weight loss program based on quality foods and a nutritionally balanced meal plan. The foundation of all Nutrisystem programs is the home delivery of portion-controlled entrees and snacks. Customers supplement these packaged foods with grocery foods, including vegetables, fruits, and dairy items. When followed, the diet is low in glycemic index and provides nutrition consistent with the Dietary Guidelines for Americans 2010.
