The 3 major intervention components are diet, physical activity, and the behavioral modification curriculum. Scheduled interactions are educational podcasts (a series of audiovisual, digital media files) paired with a follow-up phone counseling session with a trained behavioral interventionist. A patient portal message will be sent to participants when a new podcast is posted. Interactive sessions will be weekly (weeks 1-16), biweekly (weeks 17-24), and monthly (weeks 25-52). The goal for weight loss is ≥ 7% of initial weight over the course of 12 months. Participants will restrict caloric intake with the goal of 1,200-1,500 kcal/day for those weighing \< 114 kg and 1,500-1,800 kcal/day for those weighing ≥ 114 kg. The physical activity goal will be for participants to gradually increase to 175-200 minutes of moderate-intensity activity per week by the 24th week. Participants will also be asked to self-monitor their dietary intake and physical activity using the "Lose It!" app.

All participants in the Comparison Group will receive a mandatory 13 contacts per year including 3 informational sessions on nutrition, physical activity and social support and 10 contacts via patient portal or email regarding intervention topics. The Look AHEAD Comparison Group was designed to be realistic, achievable, and an acceptable intervention that encouraged optimal study retention.
