The incidence of nonalcoholic fatty liver disease (NAFLD) is increasing year by year in China, and the incidence is becoming younger, becoming one of the most common chronic diseases than viral hepatitis in today’s society. Currently, there is still a lack of effective treatment for NAFLD patients, and the main focus is on prevention. A healthy lifestyle is an effective measure to control NAFLD. First, control the diet The treatment of fatty liver patients should start from controlling the diet, not to eat too much, and not to overeat. At the same time, pay attention to the reasonable combination of nutrition, do not eat or eat less animal fat, sweets, less nuts, refuse to drink alcohol, eat more vegetables, fruits containing less sugar, less snacks, and no extra meals before bedtime. Exercise More exercise can not only consume excess energy, but also increase the sensitivity of insulin receptors to maintain relatively normal blood lipid and blood sugar levels. At least 30 minutes of aerobic exercise (such as jogging, cycling, swimming, etc.) at least three times a week for patients with NAFLD. It does not matter which type of exercise you take, the key is that you like it and are interested in sticking to it. At the same time, a certain amount of exercise must be achieved. A reasonable rate of weight loss is 0. 5-1.0 kg/week. Total weight reduction up to 5% or more. Third, abstain from smoking and limit alcohol About smoking and minimal or moderate alcohol consumption should be advocated in NAFLD patients. Smoking cessation can be a basic goal for the prevention of metabolic syndrome because smoking is a risk factor for morbidity, especially for cardiovascular disease. Alcohol itself is damaging to the liver, so it should not be consumed in excess.
