Weight loss through friendship: a new trial tests spreading healthy habits via social networks
NCT ID NCT07798557
First seen Sep 01, 2026 · Last updated Sep 02, 2026 · Updated 1 time
Summary
This trial tests whether teaching Black women with obesity to share Mediterranean diet and lifestyle tips within their social networks leads to greater weight loss and healthier habits than a standard program. Researchers will compare two groups: one that follows the diet alone and one that also learns to spread the information to friends and family. The study includes 532 participants and their network members, measuring changes in weight, diet, and physical activity over 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A behavioral program that teaches participants to share Mediterranean diet and lifestyle changes within their social networks
- What this could lead to
- If it works, this could point toward a low-cost, community-based strategy for weight management that spreads health benefits through social circles.
- What could go wrong
- The trial is early and relies on participants actively sharing information, which may not happen consistently. Results may not apply beyond the specific group studied.
