Does Nutrisystem work?

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 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.
