The first consideration in food selection is quantity, and try to choose foods with relatively low energy density. For example, try not to eat sugary foods, all kinds of sweets, biscuits, chocolate, cakes, bread and butter, sticky foods such as glutinous rice. In addition, there are all kinds of high-fat foods, such as nuts, fried foods and even various sauces. Try to eat less mayonnaise, salad dressing, noodle sauce, fried sauce and sesame sauce. All kinds of fruits are healthy food, although mango, durian, litchi and winter jujube have high sugar content. But like other fruits with moderate sugar content, they all contain three treasures, namely dietary fiber, minerals and vitamins, which provide energy for nutrition. Eating them in moderation can not only help them lose weight, but also help them lose weight.
