The Nutrisystem diet is a balanced, low-calorie diet that is similar in nature to the Jenny Craig diet or the glycemic index diet. It offers specialized plans for men, women, diabetics and vegetarians. Plan followers are required to provide proteins, dairy, fruits and vegetables to supplement the diet plan's prepackaged meals. However, research about the actual results of the diet and its safety are limited to information from Nutrisystem itself, according to U.S. News and World Report.
HowStuffWorks points out that the meals from Nutrisystem include preservatives. While such preservatives are in many foods on grocery store shelves, preparing meals at home using fresh fruits, vegetables and meats allows consumers to limit their exposure to them. Some diet plan followers are discouraged by the typical 1- to 2-pound weekly weight loss and quit. As with any diet, before beginning the Nutrisystem plan, individuals should speak with their doctors concerning its suitability for their particular needs.Learn more about Diet Plans
