**What is the role of exercise in managing weight?**
Exercise plays a vital role in managing weight by boosting metabolism and increasing caloric expenditure. Engaging in regular physical activity helps build lean muscle mass, which can elevate resting metabolic rate, leading to more calories burned even at rest. Exercise also enhances appetite regulation and reduces stress-related eating behaviors. When combined with a balanced diet, regular exercise supports long-term weight loss and maintenance, promotes overall health, and decreases the risk of obesity-related diseases.
