NCT ID NCT05799846
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This study compares three different 12-month online weight loss programs for adults with obesity. One program focuses on standard behavioral techniques, another on preventing future health problems, and a third on promoting future benefits of a healthy weight. Researchers aim to see which approach leads to the greatest weight loss and what personal traits predict success.

- What this could lead to
- If successful, this study could identify the most effective psychological strategy for weight loss, helping tailor programs to individual needs.
