A balanced diet consists of sugars (starch), fats, proteins and other micronutrients for direct energy supply, and preferably a certain amount of dietary fiber. The body first consumes sugars, which are most directly and efficiently utilized, so the patient’s diet should first ensure the proportion of foods that provide sugars (i.e., staple foods). If this part is not provided sufficiently, the organism starts to consume the body’s reserves of fat and protein, converting them into sugar for energy supply, a process that increases the burden on the liver and other major organs and is therefore to be avoided as much as possible. The high quality and efficient use of protein should be absorbed by the body and then synthesized into tissues, not supplying energy. Therefore, patients and family members who have the idea of using large amounts of supplements and small amounts of staple foods should realize that this will have the opposite effect.
