Using Technology to Investigate Lapses in a Weight Loss Program Among Individuals With Overweight and Obesity

All participants will participate in the same remote, behavioral weight loss program. As part of the baseline assessment, participants will be asked to watch a series of custom-made videos on the study's dietary and physical activity prescriptions, dietary self-monitoring, self-weighing, and cognitive-behavioral skills to facilitate engagement in study prescriptions. Participants will be prescribed a reduced-calorie diet that will be individualized based on the individual's starting weight and weight loss goal (recommended goal of 5-10% weight loss over 12 weeks). Participants also will be prescribed a goal of 150 minutes of moderate-to-vigorous physical activity per week. They are also given, free of cost, a Fitbit Charge 5 health tracker, the Fitbit Aria Air digital scale, and a MyFitnessPal Premium subscription for the duration of the study.
