Scientifically speaking, not eating in the afternoon is an ancient way of keeping in good health, but it is not in line with modern life. The ancients got up at 4 or 5 o'clock in the morning and rested in the dark at 6 or 7 o'clock, while the modern people mostly slept at 9. 10 or even midnight, so it did not conform to the laws of modern life. However, it also has some reference significance, that is, eat less at dinner, reduce the burden on the stomach, and not hoard fat at night, which is easier!
