Summary
This phase III trial tests whether telephone-based Acceptance and Commitment Therapy (ACT) helps overweight or obese adults lose more weight than standard behavioral therapy. About 418 participants will receive coaching over the phone and use a Fitbit and scale to track progress. The study aims to see which approach leads to at least 10% weight loss.
