Summary/Abstract: This chapter highlights the critical roles of ghrelin, insulin, and leptin in regulating energy metabolism, emphasising their complex interactions. Understanding these hormonal mechanisms is crucial for developing strategies to manage body weight, treat metabolic disorders, and combat diabetes. Ghrelin increases hunger, food intake, and fat storage while influencing glucose levels and insulin sensitivity, especially during caloric restriction. Insulin promotes glucose storage, protein and lipid synthesis, and inhibits fat breakdown, essential for maintaining glucose homeostasis. Leptin, on the other hand, reduces food intake, boosts metabolic rate, improves insulin sensitivity, and plays roles in reproduction and immunity.
