Summary
Brief summary (as posted)
This phase III trial compares telephone delivered Acceptance and Commitment Therapy to standard behavioral therapy for improving weight loss in overweight or obese participants. Acceptance and Commitment Therapy focuses on increasing willingness to experience physical cravings, emotions, and thoughts while making values-guided committed behavior changes. Acceptance and Commitment Therapy may work better at improving weight loss compared to standard behavioral therapy.
