Of course it makes scientific sense. I just got up in the morning, and my stomach function didn't really work at first. It is not advisable to eat too full and indigestible food, so as not to increase the burden on the stomach. It is advisable to eat porridge or soft breakfast that is easy to digest, and it is appropriate to be full at six points. Lunch time is the time when people begin to feel hungry after working or exercising for several hours, with increased gastric acid secretion and enhanced gastric motility. At this time, they need to eat some high-protein and high-calorie foods to supplement their nutrition. In order to eat well, they should be full from seven to eight. Dinner time means that people consume certain nutrition and energy after work or exercise in the afternoon. Under normal circumstances of not working or staying up late at night (it is recommended to rest at 2 1-22 o'clock), it is appropriate to eat digestible food for dinner to supplement the nutrition and energy consumed in the afternoon, and it is appropriate to be full for five minutes. If you are full at night, it will be converted into fat and stored, leading to obesity. Eating midnight snack is not recommended.
Three meals a day has been a habit of China people for thousands of years. Through the nutrition absorbed by three meals a day, the consumption, absorption and utilization of the human body can be improved, so as to ensure the energy supply throughout the day and better work and study.
