886. Put "GLP-1" on a label and you can sell almost anything right now: supplements, snacks, drink powders, even a gadget that sits next to your toilet.

Some of these products are designed for people taking GLP-1 medications, who can have real nutritional needs. Others promise to boost your body's own GLP-1 as a path to weight loss. That second pitch is a lot shakier, and the reason comes down to what these medications are and how they work.

Monica separates the science from the marketing:

What GLP-1 is, and what this gut hormone does after you eat
Why semaglutide, tirzepatide, and retatrutide aren't technically "GLP-1s," and what receptor agonists, dual agonists, and triple agonists are
The more accurate names the medical community has proposed for this drug class, and why none of them has stuck
How fermentable soluble fiber feeds your gut microbiome, produces short-chain fatty acids, and raises natural GLP-1
Why nobody was talking about boosting natural GLP-1 until these medications took off
A bathroom device that estimates your fiber intake from the air around your toilet, and why it doesn't measure GLP-1 at all
Why these medications don't treat a GLP-1 deficiency
Why your natural GLP-1 breaks down within minutes while semaglutide stays active for days, and what that difference means for appetite and weight loss
Why eating more fiber is still a good idea, even if it won't do what the label implies

Nutrition science you can trust, in plain English.
