What is one benefit of regular exercise related to metabolic health?

Regular exercise is highly beneficial for metabolic health, particularly in how it improves insulin sensitivity. Insulin sensitivity refers to how effectively the body's cells respond to insulin, a hormone that regulates glucose levels in the blood. When a person engages in regular physical activity, it enhances the muscle cells' ability to take up glucose from the bloodstream, thus lowering blood sugar levels and reducing the risk of developing insulin resistance and type 2 diabetes.

Improved insulin sensitivity also facilitates better lipid metabolism and contributes to a healthier body composition by aiding in the reduction of fat mass while preserving or building lean muscle mass. Consequently, this metabolic efficiency helps maintain stable energy levels, enhances overall metabolic rate, and can contribute to weight management.

Other answer choices do not align with the benefits of exercise; for instance, increasing the risk of chronic diseases, through mechanisms such as inflammation or sedentary behavior, contradicts the established protective benefits of exercise. Dehydration of tissues and weight gain are also unfounded in the context of regular, properly conducted exercise, as it typically promotes hydration and can support weight loss or maintenance instead.
