GLP-1 and GIP are the two incretin hormones that amplify insulin after meals. Research shows how they work, differ, and drive modern obesity drugs.
Incretin BiologyL-Cells and K-Cells: Where Incretin Hormones Are Made
L-cells make GLP-1, K-cells make GIP. These enteroendocrine cells line your gut and control up to 60% of your insulin response after eating.
