If you want to control your weight after pregnancy, your dietary principles should be diversified, with smaller meals and more frequent meals, and a combination of coarse and fine food. In the middle of pregnancy, the intake of high-quality protein food should be increased appropriately, such as lean meat, eggs, fish, etc., about 15g per day. Carbohydrates should account for 50%-60% of the daily calories, 200-450g of staple food, and attention should be paid to supplementing multivitamins and minerals. During pregnancy, you should also pay attention to eat more green vegetables and foods high in dietary fiber, which can improve the symptoms of constipation during pregnancy, but also slow down the rise of blood glucose, half an hour after the meal to have more than 30 minutes of moderate exercise.
