It may take a while for the human body to adapt. First, there is obvious gastrointestinal dysfunction, which in turn leads to pathological changes in other organs of the body. People who eat only one meal a day will certainly live shorter lives. Specifically, how long can you live, or how long can you live. The key is to drink enough water.
If the body's intake of nutrients is enough to sustain life, then you can live a normal life. But living doesn't mean that there will be no problems in the body, and it can't guarantee health.
Historical changes of three meals a day;
After entering the mature farming civilization, the diet began to become regular.
From the Zhou and Qin Dynasties to the Han Dynasty in China, ordinary people ate two meals a day, morning, noon and evening. The breakfast is called glutinous rice, in the morning 10- 1 1, and the dinner is called glutinous rice, at 3-5 pm.
In the Han Dynasty, the ruling class began to eat three or four meals a day, while ordinary people generally ate two meals. "Hanshu Huainan Wang Li Liu Changchuan" said that "everyone has three meals a day, and they pay for their own food and salt cooking utensils." It means that Liu Changmou rebelled and was sentenced to move to Shu. Wendi ordered him to have three meals a day.
In the Tang and Song Dynasties, ordinary people had three meals and another lunch, and the importance of this lunch increased day by day.
However, China is too big and its development is extremely uneven. Coupled with the frequent wars and disasters in ancient times, ordinary people actually have three meals or two meals in parallel for a long time. Even in the same place, there are some periods of three meals and some periods of two meals.
The imperial diet in Qing dynasty was a two-meal system, namely breakfast and dinner. The "two-meal system" in Qing dynasty is very different from that in Qin and Han dynasties in terms of time arrangement. Generally, breakfast is after Mao Zheng (after six or seven in the morning), and dinner is mostly at noon and noon (12 to 14).
In the Qing Dynasty, "imperial meals" were "two bright and four dark": in addition to two main meals (big meals) of breakfast and dinner, there were two side meals of "morning" and "evening".
For ordinary people, the main reason for the regularity from no meal to two meals and then to three meals is that with grain reserves, the disposable food of ordinary people has increased, and it becomes natural to eat one more meal. The development of agriculture is a prerequisite for all this.
The three-meal system is also attributed to the arrival of industrial society and the beginning of the 8-hour work system. Nowadays, three meals are still the way for ordinary people to protect their energy and synchronize the pace of social production.
As in ancient times, for the upper class and the rich, they have always been ahead of ordinary people in the number and time of meals every day, which is due to wealth and social reasons, which is the embodiment of their identity.
