Research indicates that the body undergoes complex changes during fasting and subsequent refeeding. Fasting can serve as a mechanism to prepare the body to grow stronger, largely due to specific growth factors like IGF-1 that are influenced by nutrient intake post-fast. Walter Longo, a recognized biologist, referred to fasting as "auto repair mode," where the body breaks down cellular components and, upon refeeding, regenerates stronger ones.
