Feasibility and Preliminary Efficacy of a Reverse Diet as a Novel Weight Loss Maintenance Strategy for Weight-Reduced Adults With Overweight/Obesity

Participants in both groups will receive a 12-week comprehensive, individually delivered behavioral weight loss maintenance intervention, adapted from the Diabetes Prevention Program (DPP) Post-CORE program. This program focuses on utilization of tools and strategies to maintain a healthy lifestyle and prevent weight regain, and is therefore most appropriate for the weight-reduced population we will enroll. While the DPP Post-CORE program includes 15 sessions delivered over 15-months, we will deliver sessions #1-12 and 15 over a 12-week period. Content for sessions 13 and 14 from the DPP Post-CORE curriculum focus specifically on Type 2 Diabetes Mellitus and Heart Disease. The informational handouts will be provided to participants, but not specifically covered in weekly meetings. Groups will differ only in specific caloric prescriptions (described in the Arms section).
