Strictly speaking, you are not allowed to eat anything, just drink more water. Drinking clear water health drinks will not make you hungry, but you are addicted to it. Because cells are constantly dividing and growing when eating, the human immune system only enters a state of self-repair after fasting for three days, which plays a very important role in fighting aging and regulating immunity. Actually, fasting is the nature of all animals. Only humans in the animal kingdom have enough food every day. It is no mystery that proper fasting is only to restore nature!
