GLP-1 in a nutshell:
What: Glucagon-Like Peptide-1 = gut hormone released after you eat
Does 3 main things:
Lowers blood sugar - boosts insulin + reduces glucagon, but only when glucose is high
Curbs appetite - slows stomach emptying + makes you feel full
Key fact: Natural GLP-1 only lasts ∼2 min before enzymes break it down, so meds are made to last longer.
Basically your body’s “I’m full, handle this sugar” signal.
