ClinConnect Summary

This clinical trial is studying the effects of a phone-based therapy called cognitive behavioral therapy (CBT) on people with severe obesity and food addiction. Food addiction means having a strong craving for certain unhealthy foods, which can lead to eating problems and negatively affect a person's health and quality of life. The researchers want to see if this therapy can help reduce food addiction, improve weight management, and enhance overall well-being for participants over 18 weeks, compared to those receiving regular care.

To join the study, participants need to be between 18 and 65 years old, have a body mass index (BMI) of 35 or higher (which indicates severe obesity), and be diagnosed with food addiction. They also need to be able to participate in phone sessions and give their consent to take part. Throughout the trial, participants will attend 12 therapy sessions over the 18 weeks, where they will learn techniques to manage their cravings and improve their eating habits. This trial aims to provide valuable information on how effective phone-based therapy can be for individuals dealing with these challenges.
