Summary
This study looks at how a 12-week aerobic exercise program affects brain activity and stress hormones in veterans with overweight or obesity. Researchers will use brain scans and stress tests to see if exercise changes how participants react to pictures of high-calorie foods and mental math challenges. The goal is to understand the link between exercise, stress, and eating behaviors.
