Other problems, if you just drink water and don't eat, just once or twice, I think it's ok, but pay attention, if you are flustered, it may be hypoglycemia.
Suggestion: If hypoglycemia occurs, I suggest you eat less or not at all, which will definitely be bad for you and affect your normal metabolism. Arranging only drinking water or eating fruit for one day every month, that is, fasting and detoxification, is also a way to clear the intestines.
In ancient times, fasting and detoxification was called "fasting", which means eating less or not, avoiding or reducing eating grains or meat, so as to achieve the purpose of improving intelligence, eliminating diseases, prolonging life, beautifying and increasing intelligence. In modern medicine, this method can adjust the acidic environment in the body to alkaline, and physical acidification is one of the causes of the disease.
Need to be reminded that not everyone is suitable for fasting and detoxification. For example, people with chronic diseases and hypoglycemia should not try it easily. Healthy people also had better consult a doctor in advance.
