Which of the following can increase a patient's sensitivity to insulin?

Regular exercise plays a significant role in enhancing a patient's sensitivity to insulin. When an individual engages in physical activity, their muscles require glucose for energy. During this process, muscles become more adept at using insulin to uptake glucose from the bloodstream, which leads to improved insulin sensitivity. Additionally, regular exercise can help manage body weight, decrease fat mass, particularly visceral fat, and enhance overall metabolic health, all of which contribute to better insulin sensitivity.

In contrast, consuming high sugar meals would typically lead to increased blood glucose levels, which might create more demand for insulin. Taking expired medications could compromise their effectiveness and might not provide any benefits related to insulin sensitivity. Finally, avoiding all carbohydrates is not an effective strategy for improving insulin sensitivity, as carbohydrates are a vital source of energy. The body needs a balanced intake of nutrients, and a complete avoidance could lead to metabolic imbalances.
