Is there any scientific basis for how long people can go without eating?

There is a scientific basis for the fact that normal people can only last for 7 days without eating. During this 7-day period, when the body's carbohydrates are depleted, the body's stored fats and proteins can be converted into carbohydrates to continue to provide energy to the body.

People can insist on seven days without eating, and can only last three days without eating or drinking, which is the conclusion of the study on the amount of substances that the human body needs to consume every day, of course, in fact, many times, human beings are able to break through this limit, although they can't do not eat completely, but they can also persist for a long time.

Normal people can live for about 3-5 days, because not eating or drinking can not only burn fat quickly, but also bring negative effects to muscles. Because it cannot provide the nutrients that the body needs for a long time, the body cannot consume protein, vitamins, calories and fats.

It can last up to 382 days, and there was a person named Babieri who insisted on a total of 328 days in order to successfully lose weight, and finally suffered from anorexia.

It varies from person to person, and normal people can generally last for more than 7 days as long as they have water to drink.

Theoretically, a person can go without eating for about a month.

But it is often the spirit that breaks down first.

Most people can't make it to the point where they break down the proteins that make up them.

When a person is hungry, the order of energy supply is ATP, followed by blood sugar, glycogen, and fat. And then there's the protein building, which is the last thing to break down your muscles for energy.

However, before that, blood glucose cannot be maintained, resulting in vascular osmotic imbalance, which further burdens the internal organs and brain, which are already in a state of exhaustion, and leads to the collapse of the living system.

A starving man has a bone in his throat that breaks, I forgot what to call it.

If there is no water at all, it can only last for about 3 days.

That is, the 72-hour ** time for disaster relief.

The human body itself is losing water, and respiratory loss accounts for a large proportion.

1. Ordinary people can live for three days if they don't drink water or replenish water through other means, and they can live for 1 or 2 weeks if they only drink water and don't eat.

2. Under normal circumstances, the human body has to replenish water every day to make hidden parts, water is an important substance required by organisms, more than 65% of the weight of the human body is water, and many biochemical reactions in the human body require the participation of water, such as the hydrolysis of sugar, respiration, etc.

3. In the process of human metabolism, many wastes will be produced and leave the human body through the sweat system, urinary system, etc., which makes the human body need to replenish a large amount of fresh water every day to maintain the normal operation of metabolism.

4. For an adult, Tanqin Hall needs to replenish 2000 2500 ml (7 9 cups) of water every day, and there is no organ in the human body that specializes in storing water, so the human body will feel thirsty soon after drinking water; However, the human body can store energy in the form of fats and sugars, and release energy when needed to meet the needs of the human body.

Dear, most people can persist for about 7 days without eating or drinking, but it cannot be generalized, and it needs to be judged according to the basic situation of the human body. Some patients are in poor physical condition and have underlying diseases, which can be life-threatening in about 3 days. If some patients are in good physical condition and have better nutritional status, they may exceed 7 days or even reach 10 days.

Even in a resting state, the human body needs energy, mainly food, and also needs a lot of water to promote the discharge of toxins from the body.
