How full is good for your health?

As the saying goes: eat well in the morning, eat well at noon and eat less at night. However, many people are not. They don't eat in the morning, eat less at noon, have a meal in Shanghai at night, and some even eat supper. I think it depends on people's living habits. For example, after working all night and falling asleep at home, can I eat in the morning? Eat when you should eat and sleep when you should sleep; Eat if you want, and sleep if you want. This is the real human nature.
