What role does physical activity play in body composition?

Physical activity plays a critical role in body composition by reducing excess body fat and improving lean mass. Engaging in regular exercise creates a caloric deficit, which can lead to fat loss when combined with a balanced diet. Additionally, strength training and resistance exercises are particularly effective in building and maintaining lean muscle mass. An increase in lean body mass is beneficial not only for aesthetics but also for metabolic health, as muscle tissue burns more calories at rest compared to fat tissue.

Therefore, incorporating physical activity into one's routine encourages a healthier body composition by promoting fat loss while preserving or even increasing muscle mass, which is essential for overall health and wellness.
