Insulin sensitivity plays a crucial role in metabolic health as it determines how effectively the body's cells utilize glucose. Increased insulin sensitivity enables the body to lower blood sugar levels, preventing conditions like type 2 diabetes. Factors such as diet, physical activity, and body composition significantly influence insulin sensitivity. Improved insulin sensitivity is associated with a reduced risk of cardiovascular diseases and better energy levels. Consequently, enhancing insulin sensitivity through lifestyle modifications can have profound implications for overall metabolic health.
