Exercise serves a vital function in managing weight by increasing caloric expenditure and improving metabolism. Regular physical activity stimulates various metabolic processes that help sustain or lose weight effectively. Exercise contributes to lean muscle mass, which boosts resting metabolic rate and aids in burning more calories at rest. Additionally, engaging in different forms of exercise, such as aerobic and strength training, promotes overall fat loss while preserving muscle tissue. Ultimately, combining exercise with balanced nutrition creates a powerful synergy for effective weight management and overall health.
