1, be sure to have breakfast in the morning, not at all.
If you want to eat staple food at noon, you can consider eating less, but there is no way. Try to eat some rice. Stewed chicken legs with potatoes should be good. Remember to peel chicken legs instead of vegetable soup.
3, eat less at dinner, mainly soup, do not eat meat, you can eat less staple food.
Set aside time in the day to eat fruit and drink water. It will be effective to exercise and arrange work and rest time reasonably.
