Diabetic people should exercise (walk, swim or cycle) for up to 2.5 hours per week as it can lower their blood glucose level.

The best time to exercise is an hour after breakfast or dinner. As exercise will lower your blood glucose levels so it is important to not over-exercise and take carbohydrates if your levels drop too low. Also, remember to drink plenty of water.

Exercising regularly is also good for preventing diabetes. According to a study, people who exercise for up to 4 hours a week or about 35 minutes a day, dropped their risk of diabetes by 80%, even if they didn't lose any weight. Studies show that exercise helps your body utilize the hormone insulin more efficiently by increasing the number of insulin receptors on your cells.
