Retatrutide is a pharmaceutical compound under clinical investigation (by Eli Lilly) that acts on three hormone receptors (GIP, GLP-1, and glucagon) to reduce appetite and body weight
Glucagon enhances multiple steps in this pathway: Increased lipolysis: Glucagon activates hormone-sensitive lipase in adipose tissue, releasing more fatty acids into circulation Reduced lipogenesis: Glucagon suppresses the enzymes responsible for creating new fat from carbohydrates Enhanced hepatic oxidation: Glucagon upregulates liver enzymes involved in fatty acid oxidation Ketogenesis: When fat oxidation exceeds the citric acid cycle capacity, excess acetyl-CoA is converted to ketone bodies, an alternative fuel source The net effect is a metabolic state favoring fat breakdown over fat storage
Beyond weight loss, patients often experience improvements in blood pressure, cholesterol levels, and blood sugar control
While the increase in risk appears modest, the findings raise important questions about how rapid weight loss and appetite suppression may affect bone health over time
