How will the body react if you only drink water and do not eat food for 48 hours?

For normal people, drinking only water for two days will use body fat.

and the reserves of protein and fat in the tissues, because there is no energy, blood sugar **, the body may be due to ketosis.

You may feel tired, weak, or dizzy.

For those who encounter the above diseases such as colds or stomach discomfort and fasting for two days, only drinking water, although it is also weak, but this gives the body a chance to buffer and recover.

In addition, there are some patients who have undergone abdominal surgery, and they wait until the intestinal ventilation is restored before eating, which is usually 48-72 hours. (also for the recovery of the disease).

According to the normal body reserves of protein, water and other nutrients.

If you fast, only drink water, you can survive for several weeks, but if you cut off water, you can only survive for a few days, generally 5-10 days of water can be life-threatening, fasting until all body fat and protein in tissues are exhausted to 50%, then death. Death can occur if you lose 10% of your body's body water if you lose water. In other words, water is more important to life than food.

What happens to the body if you fast for 48 hours and drink only water? 48 hours, that is, two days, only drinking water for two days, I think for acute gastroenteritis.

I've had stomach problems. Or people with toothaches, or people who have a cold and fever and don't want to eat. Under normal circumstances, human beings cannot endure hunger for two days, at most they will start to eat something in one day, even if they do not eat staple foods, they will eat some fruits and vegetables to satisfy their hunger.

In general, for physical fitness.

For example, in the past war years, due to food shortages, the soldiers who also had to participate in the War of Resistance also occurred, and now in special circumstances, there will also be two days of not eating, occasionally it will not necessarily cause great damage to the body, but if it is often like this, it will affect the health of the body, for example, some **people want to use such a method**, then it will outweigh the loss.

The body will have a very hungry reaction, and the body will be very uncomfortable, there will be dizziness, and may even be accompanied by nausea and vomiting, and all the functions of the body will be reduced, and the body will be very weak.

If this is the case, then the blood will become viscous, and the heart will beat very fast, and there will also be hypoglycemia, low blood pressure, palpitation, dizziness, nausea, retching, acid water in the stomach, etc.

The stomach rumbles, the body is a little weak, only drink water for two days, the body is generally not a major problem, if you don't eat for a long time and only drink water, you may die in a serious way.

You will become very tired, you will be very unmotivated, and you will not have the energy to do anything else, you will always be sluggish, you will be very weak, and you will be very hungry.

If you don't eat or drink water for 7 days, it's called: Bigu

Assuming that each valley is 7 days, it is generally recommended to have an interval of 2-3 months.

It doesn't matter how often you go to the valley, what matters is whether you practice regularly and eat less and exercise more during the interval. For the best of my friends.

"Bigu" originates from the Taoist health regimen "not eating grains", which is a common way of health preservation used by the ancients. It originated from the pre-Qin period and was popular in the Tang Dynasty, and is also known as the valley, the valley, the grain, the grain, and so on.

The earliest record of Bigu comes from "Zhuangzi Wandering": "The mountain of the contempt of Gu shoots, there are gods and men living in Yan. The skin is like ice and snow, and it is like a virgin, it does not eat grains, sucks wind and drinks dew, rides the clouds, and flies the dragon, and swims beyond the four seas.

As a kind of health regimen for longevity, Bigu is also recorded in many ancient books and classics.

The traditional Bigu is divided into two main types: taking qi and taking medicine. It is mainly carried out through hunger strikes and adjusting breath (breathing), and its effectiveness currently lacks scientific evidence; Taking medicine Bigu is to regulate the body's functions by ingesting other complementary foods (nuts, Chinese herbs, etc.) while not eating staple foods (grains).

Under the guidance of science, targeted Bigu is indeed beneficial to the health of the body, but its efficacy should not be exaggerated, and the scientific principles still need to be studied.

Everybody knows that water is more important than any food, and if a person doesn't drink water for three days, he collapses and his internal organs start to become dehydrated, which is often worse than any external injury

And if you only eat and don't drink water, you can last for about 7 days, because food contains a certain amount of water, but these are far from enough for our human body, a huge and sophisticated physiological machine

So if you only drink water and don't eat, you can only last for 7 days at most.

Depending on the individual's physique and willpower, the time for which they can persist is also different.

Although the human body can adapt to a long period of fasting to a certain extent, it is very dangerous for the human body to go without meals and drink only water for seven days. In this case, the body will have to rely on fat and muscle for energy and nutrients, which will lead to a decrease in the body's metabolic rate and the gradual failure of the body's organs and systems. In this case, the human body will experience severe symptoms such as dehydration, low blood sugar, low blood pressure, arrhythmias, muscle wasting, and may even lead to death.

Therefore, it is very dangerous to skip meals and drink only water for seven days, and it is not recommended to try it. If you want to improve your health, choose a healthy diet and exercise, and consult a medical professional or dietitian for advice.

Water is the source of life, and drinking water in moderation is the key to avoiding some fatal consequences. What are fatal consequences? Imagine that you are deep in a desolate desert, with no oasis, no water source, and you have drunk the last drop of water with you.

If it continues, and the water is not replenished in time, the following terrible results can occur when you are dehydrated to the limit.

What happens to your body when you become dehydrated?

Once the normal body is dehydrated, the body's tissue fluid decreases, and we feel weak under the impetus of exercise or high temperatures. At first, we may feel thirsty and sleepy, and further we may experience a mild headache. People will gradually start to become irritable, nervous, and their physical functions will deteriorate.

Scientific studies have shown that even a small amount of dehydration of one percent can have a negative impact on mood, concentration, memory and motor coordination. The indicators in the human body often vary from person to person, but various data show that the cerebrospinal fluid of brain tissue is reduced due to dehydration, which leads to a decrease in brain volume and affects the normal function of cells for a short period of time.

In the absence of water, an adult can only survive for a week.

25 hours without water: bad breath.

Dehydration minimizes the amount of saliva secreted in the mouth, and one of the functions of saliva is to inhibit the growth of bacteria in the mouth, so once dehydrated, the bacteria in the mouth will grow rapidly, resulting in bad breath. When you find yourself in the desert with bad breath and no water, it means that death has begun to target you.

39 hours without water: **Becomes very dry.

If you don't hydrate in time at this time, your mind will become dizzy, which will reduce your blood volume, and not only will you start to get drier, but your whole body will become tight, peeling, and itchy.

48 hours without water: sudden cold and sudden heat.

After two days of not drinking water, your body begins to experience sudden cold and hot symptoms. One second you feel as cold as Antarctica, and the next second you feel like you're over a mountain of flames. According to Dr. John Higgins of the University of Texas, the normal body temperature of a human being should be maintained below 37 degrees Celsius, and when dehydrated, a person's body temperature rises and stabilizes to a degree Celsius, affecting the normal activities of organs in the body.

63 hours without water: muscle cramps.

When the body heats up, the muscles will not function properly, and with the continuous loss of sodium, potassium and other substances, the muscles will spasm, and you have reached the stage of severe dehydration.

72 hours without water: headache.

In the final stage, all you can feel is a splitting headache. Because the dehydration starts to spread to your head, the skull hurts as if it was being slammed with a sledgehammer until the brain dies.

If you only drink water and don't eat, how many days can a fat person live? I can't believe it after reading it.

Not for a short time, but for a long time.

It's very simple, you will die, there have been experiments for a long time, normal people simply can't hold on for so long and die, only some people with extremely strong physical fitness and willpower beyond normal people can hold on for a little longer.

This is in the case of not wading in water at all, eating fruits and other things with moisture cannot be counted, and as long as you eat enough of those things, you can't die).

Usually, there is moisture when you eat and enjoy meat, and you can last a week!

I can go a week without water, and I do it often

Experiments have proved that people can live up to 2 weeks without food, but only 3 days without drinking water. So you won't die if you don't eat for 7 days - but if you're not very strong

Suggestions: The internal organs of the human body may enter a state of failure, and the end of life is not far away.

Experts from the Chinese Nutrition Society believe that the human stomach is generally emptied 3 hours after eating, and the body's calories are gradually consumed by metabolism during activities, followed by hunger. If you do not replenish energy for a certain period of time, you will experience dizziness, fatigue, retching, hypoglycemia and other uncomfortable symptoms. An average person can maintain a lifespan of 3 days without any food and water, and 7 days if he only drinks water.

A professor of biochemistry also commented: "The limit of life in a state of starvation is 7 days. People are going to eat, and people in distress who have been cut off from food due to natural disasters or other reasons will always try to find all the food that can be swallowed, even grass roots and tree bark, so it is not easy to determine their fasting time.

But there are also some people who have been able to survive for a long time because of their own hunger strikes. They have lived much longer than experts and scholars say that they can only live for a few days, and some have lived for dozens of days. Why?

This is related to the "stock" in the body on the one hand, and the metabolic level of the body on the other. Hunger strikers are bound to become weaker and weaker, and their "energy" consumption will be reduced to a minimum, so that their lives can be prolonged relatively. As for what is the limit time to fight hunger?

It's still a mystery.
