What will happen if you don’t eat for a week

SUBSCRIBE

 

Suppose you decide not to eat anything for a whole week and only drink water. What would happen to your body in this case and how many kilos could you lose?



What will happen if you don’t eat for a week



In short, not eating for a day is not harmful, as long as you avoid fasting with vegetable smoothies and mashed potatoes. But not eating for a whole week to lose weight is a bad idea.


Why are 7-day fasts impossible, in a nutshell?


After drinking water for a day or two, you will lose weight and probably reduce your appetite. It will be much easier for your body to maintain healthy body weight.


But what happens after a week of fasting? It has been scientifically proven that people who undergo these extreme diets lose a lot of weight, become thinner, and simply die. Among other things, prolonged fasting affects health, causes chronic diseases, and shortens life expectancy.


What happens to the body if you don't eat?


In the short term, not much happens. You may experience mood swings (irritability, tiredness) due to low blood sugar levels. But if you drink enough water, you will feel fine.


Of course, you will lose some weight, and this is already at the end of the first day. But most of all, your hormonal, digestive and nervous system will get the reboot it needs and will function better.


Usually, a person can last a long time without food, but not without water. That is why dehydration is much more dangerous than hunger because it paves the way for many chronic diseases.


Therefore, having decided to go a day without food, completely exclude caffeine and alcohol because of their diuretic effect.


What happens if you go a day without eating?


The method of intermittent fasting or fasting is to go 24 hours without eating. During this period, you can only drink water and for one day you should eat pureed and easily digestible soft foods (vegetable purees, smoothies, soups, etc.) so as not to strain the gastrointestinal tract.


Intermittent fasting is really beneficial: it normalizes blood pressure and has a positive effect on metabolism.


One intermittent fasting a week is usually considered harmless if there are no metabolic disorders (e.g. chronic gastrointestinal conditions such as Crohn's disease or diabetes, pancreatitis, gastritis, etc.


What will happen to your body? 


After 24 hours, you probably won't even notice that you haven't eaten. The specific hormone ghrelin stimulates the hunger center in the hypothalamus, which in turn sends nerve impulses to the stomach, causing a rumbling in the stomach and an unpleasant sucking sensation under the spoon. This is a normal physiological phenomenon.


The last meal is digested in about eight hours, then the body releases the glucose accumulated for some time and the rest of the 24 hours of fasting is transferred to glycogen and fat reserves.





But if you fast for more than a day, the body realizes that something is wrong and it's time to conserve resources. And instead of fat tissue, it will start converting protein reserves into energy, i.e.

 

Essentially getting rid of muscles, because they are the most energy-consuming parts of the body and are superfluous in a state of starvation.


What are the side effects of water fasting?


In general, the first days without food for the body will pass painlessly. However, by the end of the second, you will already feel some discomfort. 


  1. First, attacks of dizziness and fatigue will begin;
  2. Secondly, you will begin to experience weakness in the main muscle groups (initially quite small;
  3. Thirdly, hypotension may begin or simply unexplained pressure jumps.


What health problems become chronic?


Even if you are young and perfectly healthy (which is unlikely), your body will collapse by the end of the first week. And the acquired health problems may become chronic:


  • Thyroid disorders.
  • Increased intra-abdominal pressure.
  • Decreased potassium levels (hypokalemia.
  • Problems with thermoregulation (temperature fluctuations.
  • Increased stress, depression, persistent weakness, and problems
  • with cognitive functions.
  • Attacks of Tachycardia.
  • Hypotension.
  • Violation of the water-salt balance.


How much can I lose weight during fasting for a week?


You will definitely lose weight if you stop eating for seven days. But how many kilograms disappear in the end is a purely individual thing. It depends on your original body mass index, metabolic rate, and muscle mass.


On average, during fasting, a person can lose 7-10 kilograms for a week, provided that he moves only moderately and does not exert himself physically


Sounds inspiring, doesn't it? But there is a problem: in practice, you will not lose fat, but dry muscle mass. In addition, calcium is gradually removed from the bones, and the internal organs become smaller - from them the body will also absorb energy by processing proteins. Endocrine disorders will begin along the chain, as the body lacks the nutrients to produce the right hormones.


What is the actual process of losing weight?


By the way, the process of losing weight largely depends on the physique. It is easy to determine the type of a woman's figure: especially for this, we have a free online calculator. On the page, you will find a detailed description of how to use them, and the results will be available in a separate field.


  1. By the way, most starving people actually die of acute heart failure because the heart is simply unmanageable due to the general waste of protein.
  2. Well, the most interesting thing is: during forced fasting, metabolism slows down. Therefore, returning to the normal diet from such an extreme diet, you will quickly regain all the lost pounds.
  3. And it will already be much more difficult to lose weight again. This is called the "io effect" and is extremely harmful to health.
  4. And yes, do not forget that you also need to be very careful to get out of fasting (especially for weeks), ideally under the supervision of doctors.
  5. Otherwise, nothing good is waiting for you, except that you are spinning around.



The greatest danger after prolonged fasting is the refeeding syndrome (withdrawal syndrome). This is what is called a strong metabolic insufficiency, in which blood sugar rises sharply and insulin does not have time to be produced in the right amount to digest it.


The body lacks the ionic compounds of calcium, magnesium, and phosphates. As a result, an exhausted person can suddenly die of acute heart failure.


How much can I fast on the water in 3 days?


Water is a natural "limiter" of calories. Therefore, it is not surprising that he loses weight quickly. Studies show that after three days on the water you will lose an average of 0.9 kg per day. But, again, almost everything is due to the expenditure of muscle mass, fluids, and stored glucose.


Can I gain weight through water?


Drinking in abundance helps to lose weight, as it limits calorie intake. But at the same time, it creates an interesting effect - the body does not have the opportunity to get rid of it indefinitely.


Does coffee help to lose weight?


In the end, excess water will accumulate, since the kidneys simply will not have time to filter it. Naturally, the weight will increase due to edema. This is a paradox.


  • Therefore, it is also necessary to drink properly to lose weight. The wellness resource recommends drinking a glass of water before each meal.
  • Thus, you can reduce your intake by an average of 75 calories, which means about 27,000 fewer calories per year.

A simple count suggests this: only thanks to this simple trick you can lose almost 4 kilograms!


How long can you live on water alone?


In general, a person can usually do without food for up to 3 days on the same water. There are reports that some lasted up to 10 days, and even allegedly without health consequences.


However, this statement seems doubtful. Without food, the body will naturally begin to devour itself. And it is not known how long it will hold out in this way.


For example, the Irish Republican Army activist Bob Sands was a healthy young man at the time of the start of his famous hunger strike in a British prison in 1981. It took 66 days (just over two months) to die of exhaustion.


Result

The human body is quite hard and can do without food for several days and even weeks. But for health, it certainly will not pass without a trace.


Of course, if you do not eat a week, you will lose 5 and 7, and even 10 kilograms. But weight loss will primarily go to the detriment of muscles and bone tissue, and then to the detriment of fat.


It is likely to lead you to exhaustion by completely undermining the cardiovascular, endocrine, or nervous system. Therefore, we strongly recommend not putting such experiences on themselves.
