Exercise has many important positive effects on metabolic diseases. These effects include improving how the body uses insulin. Exercise also helps to regulate how fats are processed in the body. Another benefit of exercise is that it lowers levels of inflammation and reduces oxidative stress. Studies have shown that doing regular exercise can lower the risk of getting type 2 diabetes. It does this by enhancing how mitochondria work in skeletal muscles. It also helps muscles take in more glucose. In addition, exercise helps to lower the amount of fat in the liver. It can also improve the liver’s resistance to insulin. This is why exercise plays an important role in preventing and treating non-alcoholic fatty liver disease (NAFLD). Moreover, exercise reduces the risk of obesity and other diseases related to it. It does this by lowering visceral fat and promoting the burning of fatty acids in fat tissue. Exercise is also helpful for protecting how the pancreas works. It can delay the decline of beta cells’ function and improve how insulin is secreted. For all these reasons, exercise is a very effective way to prevent and treat metabolic diseases without the need for drugs.
