What is being tested?
The trial is testing whether exercising in the morning versus evening has different effects on weight loss, sleep quality, eating habits, and other health aspects. Participants will be randomly assigned to one of two groups: those who exercise in the morning and those who exercise in the evening.See study design
What are the potential side effects?
Since this trial involves physical activity rather than medication, side effects may include typical exercise-related issues such as muscle soreness or fatigue. However, these are generally mild and decrease over time as fitness improves.
