How many days can a person live without meals at most?

People can generally live for about 1 month without eating and drinking water, but some studies have also shown that they can live for up to 3 months, and ordinary people can live for three to five days without eating or drinking, but it is only a limit of research and challenges. Normally, the nutrients that a person needs each day include glucose, fat, protein, electrolytes and water. When people don't eat, they can't provide the nutrients mentioned above.

In the absence of sugar intake, the human body relies on the fat and protein in the body to provide energy, and burns the fat in its own body or burns protein as a calorie. However, drinking water alone can ensure hydration, but it cannot ensure electrolyte intake, and after a long time, the patient will have cachexia, severe consumption, electrolyte imbalance, and eventually death.

In medicine, it is generally accepted that a person is normal, "three days and three nights in succession without eating or drinking, and will die". If you don't eat rice, eat snacks, fruits, ......Wait, that may lead to malnutrition (possibly fatal) for many years at most, at least for a long time without death. If you only drink water (including nutritious water such as milk), it is generally considered to be about 7 to 10 days of death.

In reality, unless there are special circumstances, such as: in a special environment such as a desert, trapped in a natural disaster, unable to physically defect and unable to move......It is basically impossible to starve to death in our daily life today. When a person is really hungry, he can't help but eat anything (unless he really has nothing to eat, and he can't get anything to eat).

If a person does not take nutrition (food), that is, does not drink water, it is 72 hours (three days) under normal environmental conditions, and if it exceeds 72 hours, human life is at risk. If there is water and no food, it will be seven days for a person to live, and eight days will be the limit of a person's life. If there is food but there is no water, it depends on what kind of food it is, and it depends on how much water it contains.

In the Sahara Desert.

There is a monkey that does not drink water, and only eats leaves and wild fruits to replenish the water in the body. If you only eat food, if there is more water in it, people will not have a problem, and how long they can survive.

The deciding factor depends on the person's health and how fat or thin the person was at the beginning of the hunger strike, and in the first 3 days of the hunger strike, glycogen stored in the liver begins to break down into glucose, which provides energy for the body. After 3 days, the liver glycogen is depleted and begins to consume the body's stored fat, at this time the advantage of fat people is revealed, and the fat will last for a long time, which is why people advocated obesity in the past.

When the fat is exhausted, the person begins to consume muscle, increase the degradation of protein, and use oxidized amino acids to provide energy, at this time the person will become very sick, headache and dizziness, extreme weakness, and the organs in the body will fail one after another, there have been examples of kidney failure in hunger strikers, and then death will come. For the average person, this period is about 4 to 6 weeks.

How many days can a person live without meals at most? Under normal circumstances, men can live for 5 days without eating, and women can live for 7 days without eating.

It is said that it is seven days, but the specific number of days depends on the individual's physical condition and psychological understanding of life, some people don't want to live, they die soon, some people want to live, they can not die for many days without eating or drinking.

It's normal for people who know how to go to the valley and go months without eating or drinking.

In the past, the news reported that it was seven days, but no one dared to do such a test because it was really dangerous and harmful to health.

Ruyi: If a person does not eat, if a person does not eat and does not drink, if a person does not eat and does not drink water, it will be boiled for ten days at most. If a person does not eat or drink, stay up to ten days.

Skip meals and live up to a week.

In the past, it should have been said that people who did not drink water for three days died and people who did not eat for seven days died, but it is estimated that it is also divided into situations, such as their own physical state, environmental factors, etc.

Life is so good now, why don't you eat, you must eat, if you don't eat for a few days, you won't have it, life, it's not worth it.

If you don't eat for a day, you will be hungry all day, so the body needs to have energy all the time, good, good. Physical health is the most important thing.

In the absence of other complications, the survival time that a person can endure starvation depends on the size of the triacylglycerol (fat) reservoir reserves.

According to research, a well-nourished person weighing 70 kg has a total energy reserve of about 161,000 kcal. If the energy consumption is calculated by 1600 kcal and 6000 kcal per 24 hours according to the different energy consumption levels of the human body, the total energy reserve can meet the needs of about 30-100 days, that is, 1-3 months. So, it is entirely possible to survive starvation for up to 1-3 months.

Metabolic changes in the body's response to starvation:

In addition to oxygen and water, energy is the most needed nutrient for life. The energy required by the body is provided by the oxidation of sugars (carbohydrates), proteins, and fats, known as the three major nutrients.

Normally, energy expenditure is mainly through the daily diet of these three high-energy substances, of which carbohydrates are the main ones.

Once these substances cannot be replenished through eating, the person enters a state of starvation and the body needs to make adaptive metabolic adjustments.
