What this trial studies

This study aims to improve long-term weight loss outcomes for adults with overweight or obesity by utilizing digital tools for self-monitoring weight, physical activity, and eating habits. Participants will engage in a 24-month lifestyle modification program, sharing their data with coaches, group members, and supportive friends or family. The program includes weekly remote meetings for the first three months, followed by quarterly group meetings and regular communication through phone calls and text messages. The effectiveness of different data-sharing partnerships will be evaluated over the study period.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with a BMI between 27-50 who can engage in physical activity and have access to a smartphone and internet.

Not a fit: Patients with certain medical or psychiatric conditions, those currently pregnant or breastfeeding, or individuals with a history of bariatric surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance weight loss maintenance and improve overall health for participants.

How similar studies have performed: Other studies have shown promise in using digital tools and social support for weight loss, suggesting this approach may be effective.
