According to registered dietitian Katherine Zelman, the NutriSystem diet is healthy and low-calorie. When properly following the diet, women eat 1,200 calories per day and men eat 1,500, which is low enough for most people to lose weight but not dangerously low. Members of the program choose menus from prepackaged foods and eat six servings per day of fresh fruits and vegetables.

On the Other: The Food Tastes Bad

ConsumerAffairs.com reports numerous complaints about the quality of the NutriSystem food, calling it "mush," "bland," "cardboard" and "disgusting." Dieters claimed they quit the plan because they could not eat the meals. Without the convenience of the prepackaged meals, many dieters fail to lose weight.

Bottom Line

NutriSystem had issues with food quality in the past and experts question whether the weight loss can be maintained once the dieter is eating on his own. However, the basic ideas of the NutriSystem program are sound and lead to weight loss. Many people find the NutriSystem program to be convenient and, compared with other diets that use prepackaged foods such as Jenny Craig, more cost-effective.
