Physical activity improves insulin sensitivity by promoting better glucose uptake in cells, allowing the body to use insulin more effectively. Regular exercise enhances how muscles utilize glucose, which helps maintain healthy blood sugar levels. Increased muscle mass from physical activity further contributes to improved sensitivity, as muscle tissue is more insulin-sensitive than fat tissue. These benefits are crucial for preventing type 2 diabetes and other metabolic disorders. A consistent exercise routine, along with a balanced diet, enhances overall metabolic health and reduces long-term health risks.
