Recommended daily calories: men: 1500-1800 kcal/day, women: 1200-1500 kcal/day (carbohydrate 50%-60% of total calories, protein 15%-20%, fat 20%-25%), fiber 30-35g/day. The principle of controlled diet is total control and reasonable structure, which must ensure the control of total calories and the ratio of carbohydrates, proteins and fats. 2. Exercise therapy: Patients are recommended to perform planned, diverse and reasonable repetitive exercises, such as jogging, swimming, aerobics, tai chi, etc., with moderate exercise intensity to achieve the optimal exercise heart rate (optimal exercise heart rate = 170 – age) and exercise time of 30-60 minutes/day to consume body fat, reduce body weight and improve insulin resistance through the exercise of large muscle groups. 3. Active treatment of primary diseases: For patients with combined hepatitis B and C diseases, active treatment of primary diseases should be carried out. 4.Medication: For patients with hypertension, diabetes, hyperlipidemia, fatty liver and other diseases, under the guidance of a physician, we should carry out medication to lower blood pressure, sugar and blood lipid. 5.Weight reduction: Obesity is a risk factor of metabolic syndrome and a risk factor of cardiovascular disease, so weight reduction is the core of prevention and treatment of metabolic syndrome.
