When it comes to fatty liver, people naturally think that it must be a result of a good standard of living, too much daily socializing, and a big belly. But the fact is, there are too many people who have fatty liver nowadays, and the reasons are not only related to a good standard of living, but also some other factors. The main factors that can cause fatty liver are: a. Liver disease, liver disease, liver dysfunction, resulting in reduced protein synthesis; too much drinking high nutrition food, low activity, resulting in weight gain too fast, too much, the formation of fatty liver. Second, malnutrition, which may be a little puzzling, the fact is that due to long-term nutritional deficiency, anorexia, malabsorption, etc., can occur in the liver malnutrition, resulting in fatty degeneration, which is also prone to cause fatty liver. Third, alcohol consumption can cause the transfer of lipid reservoirs to the liver, resulting in the accumulation of fat in the liver. In turn, alcohol can cause liver toxicity and decreased liver function, which eventually leads to the development of fatty liver. Fourth, is what we usually call improper diet, eating high-fat, high-sugar food increasing, when the calorie intake is greater than the calorie consumption, the excess calories are accumulated in the form of fat, thus causing obesity, leading to the occurrence of fatty liver. Thus, it can be seen that the factors that trigger fatty liver are rather complicated. This is because fatty liver is not formed in one day, and running is an energy-consuming fat loss exercise, which first consumes glycogen in the body, and then gradually starts to consume excess fat in the body as time and intensity increase, which can consume the fat accumulated on the liver and improve fatty liver. However, if the fatty liver is combined with liver damage, on the basis of appropriate exercise and diet, the appropriate symptomatic treatment is needed.
