NutriSystem Nourish Diet plan is a "sen you the food" diet plan operated by NutriSystem, Inc.(NASDAQ: NTRI) of Horsham, Pennsylvania. The NutriSystem Diet is based on the Glycemic Index of Carbohydrates. Combined exercise, and frequent smaller portioned meals, the glycemic index diet is supposed to reduce hunger (due to a constant blood glucose). There is some support for weight loss and health benefits of low glycemic-index diets in controlled scientific studies, however, some other studies have suggested there is no long-term benefit to these diets. It was founded by Stacie Mullen, a television personality, in 1991 when the company was going to produce 20 breakfasts, lunches, dinners, desserts, and snacks.
