Being more active is an important part of your pre-diabetes plan. Regular activity and exercise will improve your blood glucose levels. Lower blood glucose levels are achieved when the glucose in your blood is used for energy during and after exercise. Muscle cells become more sensitive to insulin, allowing for better storage and usage of glucose for energy. Cells in the liver also become more sensitive to insulin, and this helps prevent the liver from producing too much glucose. In essence, insulin resistance improves with regular exercise, and gradually blood glucose levels go down. Exercise has added benefits of strengthening your heart, helping to lower blood pressure, and helping with weight loss. Routine exercise is vital to the process of stopping pre-diabetes from progressing to diabetes, and improving your general health.
