How does Mounjaro affect metabolism?

Mounjaro (tirzepatide) affects metabolism by mimicking two natural gut hormones (GLP-1 and GIP) that help regulate appetite, fullness, and how the body handles energy. This leads to eating less, steadier blood sugar, and a shift towards using stored energy, which together support weight loss. It also slows how quickly the stomach empties, helping people feel fuller for longer and reducing calorie intake. In the UK context, it’s used within NHS services for type 2 diabetes and obesity management plans that include diet and activity changes, which further support healthy metabolic function.
