According to WedMD, the Nutrisystem diet can aid in weight loss if adherents eat the prepackaged meals, supplement them with only healthy foods such as fresh vegetables and fruits, and avoid drinking alcohol and eating out. The meals from Nutrisystem are generally nutritious and low in calories. The company recommends dieters add moderate exercise to their weight-loss plan.
The prepackaged food from Nutrisystem contains "smart" carbohydrates that do not increase blood sugar when compared to other foods. They also contain fewer calories than other meals, which is one of the main contributing factors in weight loss. Foods from Nutrisystem are designed so that people gain about 50 percent of their calories from carbohydrates, 20 percent from fat and 25 percent from protein.
The company ships prepared meals and snacks to the dieter's home and offers customized plans for adult men and women, seniors, diabetics and vegetarians. Typical breakfast offerings include muffins, granola cereal and pancakes while lunches and dinners include choices like tacos, pasta, soup and pizza. Desserts are usually brownies, cookies or cake. In addition to the pre-packaged breakfasts, lunches, dinners and desserts, dieters are instructed to supplement the diet with fresh produce, protein and dairy products from the grocery store.
