There may be some herbal supplements that impact GLP-1 release to some extent, but what is being talked about here are synthetic GLP-1 receptor agonists.

GLP-1 agonists? Well they derived them from a lizard, so, uh… sort of? But no, no foods you eat are really going to have GLP-1 agonists in them, not to any meaningful degree anyway. Plus if you’re eating them they have to survive at least part of the digestive tract, which means you need even more since some of it’ll be lost.

Your body produces GLP-1, but it lives in the blood for like minutes. The innovation was finding a chemical that tickles the same receptors but survives in the body for days at a time.
