Eat low-calorie food, vegetables are not high in calories. Never eat fried products, cakes, condensed milk of cheese, chocolate and biscuits to lose weight; Melon seeds, peanuts, pine nuts, etc. You can't eat too much fruit. Fruit is rich in sugar. Eat 2/3 small bowls of rice as the staple food. Meat can be eaten at will. Eat boiled eggs instead of fried eggs. Eat white rice instead of soup. Do not cherish the leftover vegetable soup. Don't dip steamed bread in vegetable soup. The most important thing is not to eat three hours before going to bed (if you are really hungry, chew cucumber), otherwise it is useless to be hungry for a whole day.
Another principle is to eat raw green food, not processed food. For example: eat fruit instead of canned fruit; Eat grapes instead of raisins.
The first task of losing weight is to shrink the already big belly. It's easy to get full after shrinking, but it's not greedy when full. It is not difficult to lose weight if you are not greedy.
Another point is persistence. Don't think that I lost two pounds this week, so I can eat easily next week. This is a big mistake.
