Buddhist precepts. Eat one meal a day, and do not eat after noon. Yu Zhengxie of the Qing Dynasty wrote in "Guisi Cungao·Lunch": "In ancient times, not being able to eat in the evening was considered a disease. People in the Song Dynasty said that the secret to longevity is: do not cover your head when sleeping at night, and eat a small amount of dinner. The secret to avoiding malaria is: drink a little wine before dawn, and do not eat after 3 p.m., which seems to be an unusual way. Buddhists do not eat after noon, saying that this is a rule set by the Buddha... The Buddha believes that those who eat at noon should beg for food from others." It is also written as "do not eat after noon." Tang Yongtong's "History of Buddhism in the Han, Wei, Jin, and Southern and Northern Dynasties" Chapter 5 of the first part: "Eat once a day, noon is the day. This is what later generations call not eating after noon."

If you do not eat after lunch, your body will be in an empty stomach state for a long time. Without food to digest, bile and gastric acid will run idle. If the empty stomach runs for a long time, bile and gastric acid will flow backwards, corrode the gastric mucosa, and form peptic ulcers and bile reflux. Moreover, the body has its own regulatory recognition. If you are hungry for a long time, the body will respond to this behavior by regulating and increasing the gastrointestinal absorption rate of breakfast and lunch food, reducing the basal metabolic rate, and converting more energy into fat.
