Exercise is essential for maintaining healthy blood-sugar levels. Regular moderate exercise enhances the ability of cells to respond to insulin and to absorb glucose. The more fit you are, the more responsive your cells will be to insulin, which helps to keep blood sugar under control. Through its positive effect on blood-sugar levels, exercise helps to prevent diabetes.
Exercising moderately and regularly is also extremely important if you have diabetes. Because exercise helps to decrease blood-glucose levels and enhances cellular response to insulin, it often lowers insulin requirements. Regular exercise has other benefits as well: It helps to decrease carbohydrate cravings, increases energy levels, and helps to prevent the common complications of diabetes such as cardiovascular disease and impaired circulation. Exercise also improves the health of the adrenal glands by defusing emotional stress, which is a primary cause of adrenal fatigue and a contributing factor to blood-sugar imbalances. Plan for at least 30 minutes of activity such as walking or biking at least five days a week.
