The idea of reversing diabetes by exercising muscles is very good, but exercise can only play a certain role in sugar control, because the pathogenesis of diabetes is very complex, insufficient exercise and reduced muscle mass are not the only cause of diabetes. Type 2 diabetes has a genetic background and is triggered by environmental factors, including a high-calorie diet, lack of exercise and chronic stress, based on a variety of genetic abnormalities. Therefore exercising muscle can increase the muscle content of the body and reduce the fat content, thus improving insulin resistance, which helps to control diabetes to some extent, but does not completely reverse it. Diabetics are more prone to muscle loss compared to normal people, also known as sarcopenia. Sarcopenia and osteoporosis are very common problems of the locomotor system in the elderly, but are not yet given much attention. Because muscle movement requires glucose consumption, if type 2 diabetics can exercise well and increase muscle mass, it is indeed beneficial to reduce hyperglycemia. It is possible that hyperglycemia will be completely or partially relieved through strict lifestyle management in the early stages of type 2 diabetes, but as age increases and the course of the disease lengthens, blood glucose will still gradually rise, and medication will be needed to intervene.
