Have a nutritious breakfast and don't be too full. Eat a full Chinese meal because you have to do physical and mental work. Just have a seven-point full dinner. Eat more fruits and vitamins, and don't eat sweets if you get fat easily. Don't eat snacks at night Oh, if you are really hungry, have an apple. This is the result of my personal experience. I used to weigh more than 100, but now I'm 90. Come on!
