Physical activity significantly influences metabolism by enhancing energy expenditure and improving cardiovascular health. Engaging in regular exercise boosts the body's metabolic rate, which helps in burning calories both during and after physical activity. It also improves muscle mass, which burns more calories at rest compared to fat. Additionally, sustained physical activity can optimize insulin sensitivity and regulate blood sugar levels. In summary, incorporating consistent physical activity into one’s routine is a powerful way to elevate metabolism and maintain overall health.
