Type 2 diabetes is becoming more common in children, as child obesity is gaining an epidemic scale. Obesity and weight gain are important conditions for the development of insulin resistance in type 2 diabetes. Genetic factors may be the basis of obesity, but diet, exercise intensity and overall lifestyle also play an essential role. Physical activity should be gradually increased to the maximum level the patient tolerates. Both aerobic and load exercises have been shown to improve glycemic control in type 2 diabetes, and several studies have shown that combining these two types of exercises is more effective than practicing them individually. Adults with diabetes and without physical restrictions should exercise for at least 150 minutes a week (at least three days). Due to all the above, it is clear that physical activity and weight regulation occupy a vital place in our diabetes therapy method.
