As the saying goes, food is the most important thing for people. In today's highly developed society and economy, it is no longer people's daily pursuit to have enough to eat. Eating well, eating delicately and eating healthily is the key. But how to eat well? How to eat healthily? Is it healthy to eat a lot and then desperately consume the calories you eat? With the emergence of such problems, some people began to advocate fasting for health. A few years have passed, is fasting effective? If a person is deprived of food for three days, what will happen to his body function?

First, the way of fasting is fasting, the full name is intermittent fasting. Its purpose is to quickly consume a lot of excess heat in the body. In fact, if we often pay attention to entertainment news, we will find that many female stars actually do this to keep fit, but there was no such name at that time. For example, Andy, Rainie Yang, Carina Lau and so on, they only eat two meals a day, which is also an intermittent fasting. The time of intermittent fasting can be controlled by yourself, such as eating only within eight hours, eating only within four hours, eating only two days a week, eating every other day and so on.

Second, the benefits of intermittent fasting have many benefits. The most obvious and typical thing is to lose weight. Indeed, intermittent fasting can effectively reduce human body weight and reduce the accumulation of abdominal fat.

Of course, apart from losing weight, intermittent fasting has many other benefits:

1 can reduce blood sugar and prevent type 2 diabetes.

2. Reduce the incidence of inflammation and some chronic diseases.

3, anti-aging, so that the body's energy and skin condition are well restored. (from cell repair and regeneration after autophagy)

3. What will happen to the body function after three days of fasting? 1. After eating for 24 hours, glucose becomes the main source of energy consumed by your body, and the blood sugar value will be reduced by about 20%.

2. When the glucose storage in your body is exhausted, start to use fat and ketone bodies to provide energy.

From the second day of fasting, although your body's energy supply has been transformed into fat and ketone bodies, your brain still needs the support of glucose. At this time, the body will produce glucose from non-carbohydrates. Generally speaking, fat and protein are used to produce glucose for the brain.

4. The decomposition of amino acids began to decrease slowly. At this time, the human body may lose a small amount of muscle, but the muscle will increase later.

5, growth hormone secretion intensified, reaching 5 times before fasting. The role of growth hormone is to reduce fat accumulation, promote wound healing and ensure cardiovascular health.

6. Hunger began to disappear after the first day of fasting, and there would be no hunger on the third day of fasting.

7. The decrease of insulin-like growth factor (IGF- 1) and the short-term decrease of IGF- 1 can improve the anti-aging and anti-cancer ability of human body.

8. The human body will decompose old immune cells and then generate new immune cells, which can effectively reduce the occurrence of metabolic diseases. For chemotherapy patients, it can increase the number of healthy lymphocytes and white blood cells in the body.

9. On the third day after fasting, the body entered a state of autophagy. Autophagy means cell repair and regeneration. When our body can't get nutrition from the outside world, autophagy will force your body to get rid of old and unnecessary cells, and on this basis, restore and repair damaged cells to gain energy.

To sum up, if we don't eat for three days, the cells in our body will go through a process of rebirth. Eliminate old cells and generate new cells. The human body will consume a lot of fat, and its physical function will be qualitatively improved. However, because the body will face a lot of dehydration, electrolyte and mineral loss during fasting, you must remember to supplement seawater.
