Answer
Exercise helps in weight loss by increasing energy expenditure. When a person engages in physical activity, the body burns more calories than it would at rest. This caloric deficit, when maintained over time, leads to weight loss. Additionally, exercise can help build muscle mass, which further increases the basal metabolic rate, allowing the body to burn more calories even while at rest.
