Obesity symptoms are a clear sign of diabetes and a major cause of diabetes. With the increase of obesity, the incidence of diabetes also increased significantly. According to statistics, the incidence of diabetes in moderately obese people is 4 times that of normal people, and 21 times that of normal people in highly obese people. In the United States, diabetic patients account for 2D3 percent of the population, 2/3 are obese, and more than 75% of them are type II diabetic. The treatment of obese diabetes includes: (1) In the case of stable disease, the daily caloric supply should be strictly restricted so that it is lower than the consumption, but the weight reduction should not be too rapid or too violent. It is generally stipulated that the daily caloric intake should be around 5020.8 kJ (1200 kcal) or reduced to 2092~5020.8 kJ (500~1200 kcal) compared with the normal requirement, that is, it is possible to make weight loss. The amount of reduction should be based on the degree of obesity and the patient’s ability to accept. Limit the diet high in sugar and fat (including vegetable oil) calories. On the basis of ensuring the basic needs of protein and various nutrients, we must reduce the “income” and increase the “expenditure”, so as to produce a negative balance between calorie intake and consumption and promote weight loss and finally reach the standard weight. (2) On the basis of calorie control, the nutritional needs of patients should be ensured. Protein intake should not be too low, about 1.O grams per kilogram of ideal body weight, try to use lean meat, eggs, milk, soy products, etc. (no pork, even lean meat contains high fat). Protein food one can fill the hunger, two can promote the body’s caloric consumption, three can reduce the body tissue decomposition. (3) meal, the Bureau of fatty meat, fried food, oil products, peanuts, walnuts and other fatty foods; dishes to steam, boil, mix and other less oil system is better. The amount of daily staple food is generally limited to 150 to 200 grams, too low is prone to starvation ketosis. As the reduction of diet may cause the shortage of inorganic salts and vitamins, so in addition to more choice of vegetables, you can eat some fat-free milk, soy milk, soy products, etc., to supplement calcium and vitamins, and if necessary, calcium and vitamin tablets can be supplemented as appropriate. (4) While adopting a low-calorie diet, the amount of exercise should not be reduced, and should be increased appropriately to improve caloric expenditure and promote the decomposition of body fat, in order to achieve the purpose of weight loss.
