Everyone wants to be healthy and light. After trying a variety of health preservation methods, some people targeted dinner-it is said that dinner is easy to accumulate fat, retain toxins, give birth to big waist, big fat legs and hyperlipidemia and hyperglycemia, so many people began to refuse dinner, thinking that this is in line with the Chinese medicine "no food in the afternoon". Can the "no food at noon" of traditional health care serve the present? There is a saying in Chinese medicine called "no food in the afternoon", which has a tradition in ancient times. For example, in the Qing dynasty, the physician specially stipulated to have dinner at 2 pm, and the meal was grand and sumptuous. When you were hungry at night, you could eat some snacks, such as porridge and snacks. But this was in ancient times. Ancient people made it at sunrise and rested at sunset. They had breakfast at 6 o'clock in the morning and went to bed early. They "don't eat after noon", and the interval between eating at 2 o'clock and sleeping at 6 or 7 o'clock is only 4 or 5 hours. Now everyone's biological clock is moving backwards. Many people often stay up late to work and go to bed after 12 at night. If you copy "don't eat after noon", it will be difficult to achieve physical fitness in the afternoon and evening. Therefore, experts believe that the schedules of modern people and ancient people are different. The biological clock of modern people is 3-4 hours later than that of the ancients, and the ancients' "no food in the afternoon" should not be copied directly. According to the living habits of modern people, it can be improved to be more suitable for our lifestyle: people with light diet at night, heavy gastrointestinal burden or poor digestive system can choose not to eat for 4 hours before going to bed, so as not to digest for too long and affect their sleep.
