In the early stage of fasting, you lose carbohydrates, not fat. You need to wait until the sugar in your body is exhausted before you consume fat. Friends who want to lose weight think that they have lost weight and that they have succeeded, but they are not.
It is not advisable for some people to lose weight by fasting. The principle of short-term weight loss is to prevent food nutrients from being absorbed by the body by blocking the intake of nutrients. This can consume energy and lose weight, so as to achieve the purpose of slimming. Although fasting can block nutrient intake, it is not recommended to do so for a long time, because the body has its own laws and is easy to cause gastric mucosal discomfort. Some people have stomachache because of gastric mucosal damage, and some people are dizzy because of excessive pursuit of fasting, which has caused hypoglycemia. Although you can lose weight in a short time, you will rebound.
I once heard a story that there are many hermits in Zhong Nanshan. These hermits live a very poor life, and they spend most of their time in meditation and penance to improve their ideological realm. A year before the mountain was closed by heavy snow, a man visited a hermit. Seeing that there was almost no food in the hermit's house, he was very worried and asked, Snow is closing the mountain soon. What if you don't prepare much food in winter?
I saw the hermit calmly say that he didn't need so much food. Tourists have been worried about the hermit's safety since he returned. After the mountain was closed by heavy snow, the tourists came to the hermit's residence again and found the hermit meditating. Later, he learned that hermits spend the winter in this way, and they usually eat, but rarely, unlike us, who have three meals a day.
It is a bit like the Taoist "Pigu", which can be divided into several types. Some are done by fasting and adjusting breathing, while others are maintained by eating something, such as eating some herbs and nuts to adjust body functions. All these require special training, and not everyone can do it.
Taoism calls this long and gentle breathing method "turtle inhaling", which means that turtles live long because they are eating gas. Generally, people who want to avoid the valley will practice this method, that is, "taking qi" to circulate qi in the body, which can resist the hunger and dizziness caused by fasting to a certain extent.
However, there are also voices of opposition. Some people say that people are warm-blooded animals, even if they sleep, they need to consume body energy. When they fasted for a day, they began to consume a lot of body energy. When they fast for more than two days, they start to burn fat. When they fast for more than three days, the symptoms of malnutrition are particularly obvious. The consequences of not eating are obvious, such as physical exhaustion and decreased immunity, because people's bodies need trace elements such as vitamins and minerals. Lack of these elements can lead to insomnia, dizziness, hair loss and anemia, and even life-threatening.
After all, most people are ordinary people, so they don't need to learn these methods to avoid the valley, so they can eat normally.
