Maintaining a healthy weight for diabetics is important because it can help to keep blood glucose levels under control, relates the Mayo Clinic Health Letter. The United States Centers for Disease Control and Prevention also indicates that people with type 2 diabetes can lower their blood sugar levels by losing weight.
Many people with type 2 diabetes are overweight. When the weight is located around the abdomen, the cells in this area of the body have more difficulty reacting to insulin. This leads to higher levels of blood glucose. The Mayo Clinic Health Letter reports that losing about 10 percent of body weight can significantly lower blood glucose. In addition, it is very important for diabetics to eat healthy foods and exercise to maintain their weights at appropriate levels.
