Is there any scientific reason for Hu Yaozhong's fitness?

This method has not been widely recognized in the medical field, and there is no scientific evidence to prove its effectiveness and safety. Although some people may lose weight and improve some health problems in the short term, in the long run, this method may lead to health problems such as malnutrition, decreased immunity and metabolic disorder, and may even be life-threatening. Scientifically speaking, the human body needs to ingest various nutrients to maintain normal physiological functions, including protein, carbohydrates, fats, vitamins and minerals. If you don't eat food for a long time, your body will be malnourished and lead to various health problems. In addition, Hu Yaozhong's regimen may lead to metabolic disorder, affect the normal metabolism and excretion function of the body, and then affect health.
