Fasted vs. Fed State Exercise for Weight Loss

This study is looking at how exercising before breakfast (fasted state) compares to exercising after breakfast (fed state) for weight loss and overall health. Researchers want to see if one way of exercising leads to better changes in your body composition (like fat and muscle mass). You might be able to join if you are 18-59 years old, have a BMI between 25-45 (indicating obesity), and are healthy enough to exercise. The study involves a 16-week supervised exercise program. The main goal is to measure changes in your body composition. The current status of the study is unclear, and it plans to enroll 40 participants.
