Participants will track their diet and exercise via a free commercial mobile app. Participants will be connected to one another via Facebook and receive behavioral counseling via posts from coaches who are present on the network daily. Each participant will get an individualized calorie goal that would facilitate a 1-2 lbs. The goals for the intervention are 175 minutes of moderate physical activity per week and an overall weight loss of 7%. The weight loss intervention is based on the Diabetes Prevention Program (DPP), an evidence-based weight loss program focused on lifestyle changes.
This study includes a behavioral weight loss program delivered entirely via on online social network. Mobile technology and social media have the potential to reduce the intensity of traditional prevention interventions and enhance outcome by delivering behavioral strategies in-the-moment and by connecting patients other patients to generate better communication and a social support system for lifestyle changes. The overarching goal of the research plan is to test ways to leverage mobile technologies and social media to increase the impact, scalability, cost-effectiveness, and dissemination potential of lifestyle interventions that reduce cardiovascular disease (CVD) risk.
