Regular physical activity plays a vital role in weight management by helping to burn calories and maintain a healthy metabolism. Engaging in aerobic exercises like walking, running, or cycling increases energy expenditure, while strength training builds muscle mass, which inherently boosts resting metabolic rate. Consistency in physical activity not only aids in calorie control but also reduces the risk of weight regain after loss. Furthermore, exercise supports overall well-being, promoting healthier lifestyle choices that contribute to long-term success in weight management.
