1, reduce the food intake with high GI value and eat more meat with high protein and low fat, such as fish, chicken and beef. Pork is not particularly recommended because it has the highest fat content in all meats. In terms of cost performance, chicken breast is undoubtedly a better choice, with the lowest fat content and more abundant in protein.

2, what is GI value: (glycemic index) "glycemic index"-is an index that reflects the degree of blood sugar increase caused by food, and is the reaction of blood sugar after eating.

GI= the area ratio of a food under the blood glucose curve 2 hours after eating, which is equivalent to the area of glucose under the blood glucose curve 2 hours after eating multiplied by 100%.

75% of GI & gt75% foods are high GI foods, and foods with GI≤55 are low GI foods. Foods with high GI are digested quickly and absorbed well after entering the intestine, and glucose can quickly enter the blood, so it is easy to cause hypertension and hyperglycemia. However, foods with low GI stay in the intestine for a long time and release slowly. After entering the blood, the peak value of glucose is low, which causes less postprandial blood glucose reaction and correspondingly reduces the required insulin, thus avoiding the violent fluctuation of blood sugar, preventing hyperglycemia, hypoglycemia and effectively controlling blood sugar.

In addition, foods with low GI are very prone to satiety, and at the same time lead to low insulin level, and insulin can promote the synthesis of glycogen, fat and protein, so eating foods with low GI can generally help the body burn fat, reduce fat storage and achieve the effect of slimming. And foods with high GI are just the opposite.

3, staple food suggestions, brown rice, buckwheat, raw oats, potatoes, sweet potatoes and other staple foods with low GI value.
