What is consumed by a person during fasting?

During starvation, the body initially consumes its fat reserves. In parallel, the reserves of glycogen in the muscles, as well as in the liver, decrease. At the next stage, the body begins to waste its own proteins, which leads to the development of atrophy of the muscular system, endocrine glands, and internal organs. In the later stages, signs of vitamin deficiency appear. If the body receives exclusively water, then it adapts for a short period to the internal “eating” of internal reserves of fats, proteins, carbohydrates, vitamins and mineral salts.
