Study of How Exercise Affects Fat Tissue Structure and Function in Adults with Obesity

What this Trial Is About

Researchers are studying how exercise affects fat tissue structure and function in people with obesity and related metabolic conditions. The study aims to understand how exercise influences key processes in subcutaneous fat that may improve body fat storage capacity without increasing fat mass. This knowledge could help develop new ways to prevent and treat insulin resistance and other obesity-related diseases. Participants are randomly assigned to one of two groups an exercise group or a no-exercise control group. Those in the exercise group will perform moderate-intensity continuous exercise, such as brisk walking, for 45 minutes at 70% of their maximum heart rate, four days a week to burn 250 calories per session. The control group will remain sedentary with no planned exercise. The study includes a 10% weight loss program followed by a high-calorie diet to regain half the lost weight, with metabolic tests conducted before and after these phases. During the study, participants will undergo a series of metabolic tests including oral glucose tolerance tests, assessments of fat cell size, adipose tissue fibrosis, and capillarization of muscle and fat tissue. Blood lipid profiles and blood pressure will also be monitored. The total duration of participation is approximately 8 to 10 months, including support to help participants lose additional weight after completing the study.
