What is the scientific basis of the sentence "Eat well at breakfast, eat well at lunch and eat less at dinner"?

"Eat well for breakfast, eat well for lunch and eat less for dinner" is something we have heard since childhood. Is there a scientific basis for listening to big talk?

The first thing is to have a big breakfast. This is because after a night's rest, our body cells have returned to their original state. At this time, our brains don't have many instructions, and our body cells are not completely in a state of tension. Therefore, at this time, it is best to keep the nutrients you eat and let the nutrients be evenly delivered to all cells in the body. Generally speaking, a perfect breakfast can have noodles, bread, steamed bread porridge and other staple foods, such as eggs or milk, and it is best to match some vegetables, so that the nutrition is more balanced.

The main function of lunch is to ensure our energy for the whole afternoon. Having a full lunch is not eating openly, but calculating your calories strictly. It is best to choose non-fried food as the staple food for lunch, try to choose vegetables cooked with less oil, and then choose lean meat, steak or fish steak with less fat as meat, so as to ensure the efficiency of the day.

As for eating less for dinner, the principle is seven minutes full and try not to affect your sleep state. The feeling of being full at seven points is that my stomach hasn't bulged yet, but I don't want to eat too much. I won't feel sorry if I take what I eat now. This is because before we go to sleep, our stomach function needs have reached the sleep state, so we must ensure that food is fully digested. If our stomach is still working hard before going to bed, it is likely to affect our sleep state. The ideal state is to sleep for at least four hours before meals.
