Group I: Overweight WomenExperimental Treatment1 Intervention
Regardless of reproductive history, each participant will be provided with six months of the commercial weight loss program, Nutrisystem® D. Nutrisystem® D is a portion-controlled, low calorie, and low glycemic index meal delivery system that provides 1250-1500 kcal/day. It has been proven to help overweight adults achieve real and sustainable weight loss results. When meals and snacks are consumed as instructed, average weight loss is 1-2 lbs per week or 15-20% body weight by the end of six months. Nutrisystem® D offers a balanced meal plan that is consistent with the nutrition recommendations of the USDA for Americans and American Diabetes Association. Each participant will be encouraged to take a daily multivitamin to help meet her micronutrient needs on the program.
