💉 Here's what GLP-1 actually is and what it does naturally in your body. GLP-1 is a hormone produced by cells in your intestine and brainstem in response to food. And it does three powerful things: 🫀 Pancreas — stimulates insulin release (lowers blood sugar) while suppressing glucagon (which would otherwise raise blood sugar). Net result: blood glucose comes down after a meal. 🫃 Stomach — slows gastric emptying and gut motility, so food stays in your stomach longer → you feel full longer. 🧠
