Although religious people have certain spiritual pursuits, they may not feel hungry under the support of spirit, but I guess there should be a limit to crossing the valley, because the physical body will really die if it doesn't eat.
Obviously, crossing the valley is not good for normal people's health. We pay attention to the balance of three meals and the combination of meat and vegetables. How can we encourage people not to eat for several days? Don't eat for a few days first, then eat and drink for a few days to make up for the hunger a few days ago. Isn't this a scene of mass overeating?
Of course, people don't expect to take extreme measures to break the valley at present, and no one wants to die. But people have taken some changes and innovations in breaking the valley, which is the popular concept of fast food. The core of this concept is to choose not to eat a day or only eat a small amount of food for a certain period of time according to one's physical condition and diet, so as to achieve the purpose of losing weight and promoting health.
Fasting is scientific to some extent. Especially for overweight and overeating people, not eating helps to reduce the burden on the stomach and promote calorie consumption. But for people with weak constitution, and people with anemia, hypoglycemia and other diseases, it is not appropriate to try this method.
Nowadays, people have created various methods for health, but the truth is often presented in the most concise way. Specific to health, that is to maintain a regular and scientific lifestyle, a reasonable diet, and moderate exercise.
