Why don't you eat after noon?
What Buddhism calls "no food in the afternoon" is not entirely a belief, but insisting on not eating in the afternoon is very beneficial to the metabolism of the body. Regarding this theory, we need to understand the concept of "afternoon flow", because this is the theoretical guidance of "no food in the afternoon".
The sages of ancient Chinese medicine found that the the twelve meridians of human body rises and falls at twelve different times due to the changes of the positions of the sun, the earth and the moon. The the twelve meridians and twelve o'clock of the human body are connected and attached with the five zang-fu organs, and a law of the activity of one meridian and five zang-fu organs at a certain moment is obtained, which is called "meridian Liu Zhu".
This concept of treating diseases and preserving health, which organically combines life and time, is different from that of western medicine. Modern chronobiology also believes that human life phenomena and physiological activities have relatively stable time rhythms, including seasons and circadian rhythms, which are called "biological clocks", so meridians play a vital role in regulating the body.
However, not eating after noon can also cause some harm. Stop eating after lunch, so that the body is in an empty stomach for a long time. Without food digestion, bile and stomach acid will idle. After idling for a long time, bile and gastric acid will have countercurrent, corrode gastric mucosa, form peptic ulcer and bile reflux. In addition, the agency has its own regulatory accreditation. Long-term hunger will make the body react to this behavior, strengthen the absorption rate of breakfast and Chinese food in the gastrointestinal tract, reduce the basal metabolic rate and convert more energy into fat.
