Proof-of-Concept Study of an Integrated Mobile and Social Network Weight Loss Intervention

The intervention includes: the Facebook-delivered Diabetes Prevention Program (DPP) Lifestyle Intervention, MyFitnessPal and the Habit app. The DPP will be delivered within a counselor-led private Facebook group. It uses behavioral strategies to help participants 1) achieve a program assigned calorie goal based on amount needed to lose 1-2 pounds per week, 2) develop a healthy diet, and 3) engage in 150-300 minutes per week of moderate intensity exercise. Participants will be instructed to use MyFitnessPal for the first two weeks, the Habit app slip tracker and exercise planner for two weeks, and the Habit app problem solver for two weeks.
