Type II diabetes often develops during adulthood, especially in obese people, those with high blood pressure and those with a family history of diabetes. Some type II diabetics have a low insulin production. Exercise is an effective treatment for type II diabetics, particularly those who have no other interfering disease. Weight reduction leads to an increased willingness on the part of muscle cells to respond to insulin by absorbing surplus blood glucose. All you need to do to burn off as many calories is exercise longer.
Exercise is also effective in preventing diabetes.
Individuals at risk of developing diabetes have a lot to gain from making a habit of a regular, enjoyable exercise.
