Good distribution of nutrients: the supply of carbohydrates in the diet should account for 50%~60% of the total calories, protein intake should account for 15%~20% of the total calories, and fat should account for 25%~30% of the total calories. 3. Reasonable meal allocation: three meals a day should be allocated for each 1/3 or 1/5, 2/5, 2/5. Apart from that, high sugar and high fat foods, such as cake, milk tea, chocolate, fatty meat, etc., should be avoided in daily life.
