Optimizing a Support Program to Help Adults Keep Weight Off After Losing It

What this Trial Is About

This research aims to find the best combination of methods to help people maintain weight loss after losing weight. Weight loss maintenance is often difficult, and this study investigates whether specific combinations of support strategies can keep weight off effectively without adding significant cost or burden. The goal is to identify which package of components works best and to understand why they may help, including if certain strategies benefit specific groups of participants. Participants will first take part in a 16-week weight loss program Phase 1. Those who lose at least 5% of their weight will move on to Phase 2, where they will be randomly assigned to use one of 16 different combinations of weight loss maintenance methods for 12 months. These methods include limiting the variety of high-calorie foods eaten, doing home-based strength training exercises, having a trained buddy for support, and attending workshops to develop skills for managing tough thoughts about weight control. During the study, participants will attend weekly group sessions and work with a Wellness Coach in Phase 1. In Phase 2, they will continue using their assigned support package and maintain contact with their Wellness Coach. Researchers will measure participants weight and gather survey responses four times throughout the study to evaluate changes. This study will last at least 12 months after randomization for those continuing to Phase 2, with ongoing monitoring of weight and participant experiences.
