Exercise serves as a powerful tool for weight management by promoting calorie expenditure, building muscle mass, and improving metabolic health. Regular physical activity can help create a calorie deficit necessary for weight loss while enhancing overall body composition. Additionally, exercise boosts the resting metabolic rate by increasing muscle mass, which burns more calories even at rest. Incorporating both aerobic and strength training can yield comprehensive benefits, supporting fat loss and muscle retention. Moreover, exercise contributes to improved mental health, increasing motivation and adherence to weight management efforts. Hence, incorporating regular physical activity is vital for long-term weight management success.
