Summary

This study tested whether a phone-based cognitive behavioral therapy program could help people with severe or morbid obesity reduce their food addiction. 154 participants received either 12 therapy sessions over 18 weeks or their usual care. The goal was to see if the therapy could lower the number of people with food addiction and improve their quality of life.
