People who usually lose weight think that the most effective way is not to eat. Just control your mouth. In fact, such a diet can't lose weight. If you don't believe it, let's have a look~
Is fat burning when you're hungry? No. When we are hungry, it is the stomach. There is no extra food broken down into glucose to supply energy to the human body. This kind of hunger information will be fed back to our brain, so we feel very hungry. However, dieting for a long time, once the body lacks energy, the first consumption is not your fat, but other nutrients. It starts from the decomposition of muscle glycogen to produce energy, that is to say, first decompose your muscle, then decompose liver glycogen to a certain extent, and then fat.
Gastric emptying is when the body tells you it's time for you to eat. If you don't eat at this time, the body will secrete glucocorticoids, which will decompose the stored glycogen into the blood. At this time, there is a risk of muscle consumption. Starvation is just hypoglycemia. If you eat less, your body will lower your basal level to protect you and store all the calories you eat. The same goes for hunger. Hungry body will also send out a warning, it will think you are in a dangerous state, and a long period of starvation will also consume the body's muscles.
It's not reliable to go on a hunger diet to lose weight. When we are hungry, our body will give priority to the mobilization of sugars in the blood as energy. With the prolongation of starvation time, the carbohydrate was exhausted and the blood glucose decreased sharply. In order to reduce hypoglycemia, the body stops burning sugars and starts to use protein as energy source. Because protein is an important part of muscle, protein consumption will directly lead to muscle shrinkage. At the end of the day, with less and less protein, fat came forward and became a fuel for the body.
However, this does not mean that dieting will definitely make you lose weight, because after dieting, the machine will react quickly, slow down the metabolism, so as to adapt to the situation of lower body calorie intake. At the same time, dieting will also make your exercise function decline. In this way, the consumption of calories is greatly reduced, and the intake and consumption of energy reach a new balance at a low level. So, it's not reliable to just diet to lose weight. If you don't have enough, how can you have the strength to lose weight? Healthy weight loss is not a diet, but to eat nutrition comprehensive health, do not let fat have the opportunity to hoard.
How much can you lose if you don't eat in one day? 1. Theoretical drop of 3-5 Jin if you don't eat or drink
If you eat about 3-5 Jin of food a day, part of it will be digested and absorbed by your body, and the other part will be excreted as stool. If you don't eat all day, your intestines and stomach will be hollowed out. Theoretically, you can lose 3-5 Jin.
2. Do not eat but drink water weight loss 2-3 Jin
If you eat about 3-5 Jin of food a day, part of it will be digested and absorbed by your body, and the other part will be excreted as stool. If you don't eat all day, your intestines and stomach will be hollowed out. Theoretically, you can lose 3-5 Jin. However, people will drink water, and their stools may not be completely drained, so they can only lose 2-3 kg.
3. The real fat loss is only 0.5 Jin
A person's daily basic metabolic calories are 1500-2000 kcal, and a kilogram of fat can provide 7700 kcal. That is to say, a day without eating or drinking actually only needs to consume 0.38-0.51 kg of fat. The rest are weight loss caused by dehydration or reduced stool.
But note: this weight loss not only hurt the body, and he just lost your water, let you have the signs of weight loss. But one day you will have to end the day of losing weight without eating. At that time, your body needs several times more intake than before to make your body function return to normal, and your appetite will naturally multiply. After dieting, you are bound to overeat. That's why almost all people who go on a diet lose weight. Unless you don't eat all the time, you'll starve to death. If you don't eat to lose weight, it will easily lead to endocrine disorders (and irregular menstruation), liver function damage, amenorrhea or infertility, osteoporosis and a series of problems. In a short period of time do not eat to lose weight does contribute to weight loss, but little do you know, lose weight do not eat completely into the weight loss error.
