Keeping Weight Off: Brain Changes Associated With Healthy Behaviors

Obesity Clinical Trial

Official title: Keeping Weight Off: Brain Changes Associated With Healthy Behaviors

Status Completed

Clinical Trial Summary

The goal of this project is to characterize changes in emotion regulation pathways associated with healthy behaviors in people who have recently lost weight and are seeking to maintain weight loss over a 1-year period.

Clinical Trial Description

Unhealthy behaviors such as overeating and a sedentary lifestyle are largely responsible for overweight and obesity which substantially increase risk for chronic conditions such as heart disease, high blood pressure, stroke, diabetes, arthritis and certain cancers. The rapid rise in obesity threatens to reverse recent gains in life expectancy and account for a large percentage of premature deaths in the U.S. Although there is evidence for the short-term efficacy of a number of methods for initiating health behavior change to lose weight, these interventions have shown only limited ability to affect significant, long-term behavioral changes in the majority of adults. In part this may be because they fail to adequately address how psychological factors that lead to relapse to unhealthy behaviors and failure to maintain long-term behavior change.

The purpose of the study is to understand brain changes that accompany participation in programs that foster healthy behaviors in people seeking to maintain weight loss. We will use MRI scans to study brain function in men and women 25-60 years old who have lost weight in the last year without surgery. Participants will be assigned to one of two programs to help them maintain weight loss and will be compensated for their time. Our goal is to gain a better understanding of the brain changes that lead to long-term success in keeping weight off, in the hope that this knowledge will assist in the development of improved treatments. ;
