The biology behind weight management
A mechanism-first comparison of the hormones and pathways that shape appetite and metabolism.
| Pathway | Mechanism | Primary Role |
|---|---|---|
| GLP-1 | Released after eating; signals fullness and supports glucose-dependent insulin secretion. | Appetite & satiety |
| GIP | An incretin hormone studied alongside GLP-1 for complementary metabolic effects. | Glucose metabolism |
| Glucagon | Associated with energy expenditure in research models. | Energy expenditure |
| Ghrelin | The 'hunger hormone' that rises before meals. | Hunger signalling |
| Leptin | Signals energy sufficiency and satiety from fat stores. | Long-term balance |
