Diabetes is the result of the interaction between genetics and the environment. Genetic factors currently there is no good way to change, while in the environment, lifestyle to start can focus on the following aspects: 1, diet control: need to control the diet, do not overeat, do not eat high sugar, high-fat food. Healthy and balanced diet, can better avoid diabetes; 2, improve exercise: to exercise properly, need to have an exercise plan. About 150 minutes of exercise per week, about 30 minutes of exercise per day, at least 5 days of exercise in 1 week. Exercise can improve the absorption and utilization of glucose by peripheral tissues, which can delay the onset of diabetes; 3. Weight control: weight gain or obesity is a more important cause of type 2 diabetes, and weight should be controlled within a relatively standard range. Adult weight BMI should be controlled below 24, that is, not overweight. By controlling body weight, the secretion of peripheral adipose tissue can be reduced to resist insulin factors. After the secretion of anti-insulin factors is reduced, insulin will be more sensitive and blood sugar will be in a more stable state, delaying the onset of diabetes.
