Exercise aids in managing weight in the long term through various mechanisms. It boosts metabolism, allowing the body to burn more calories even at rest. Regular physical activity also helps maintain muscle mass, which is vital for sustaining a healthy metabolism. Beyond calorie burning, exercise promotes behavioral changes, such as better food choices and reduced cravings for unhealthy snacks. Additionally, remaining active enhances accountability and motivation in weight loss efforts, making it easier to maintain a healthy weight over time.
