how much of what we believe about pharmacology actually comes from appetite threads

Question

how much of what we believe about pharmacology actually comes from appetite threads. I would rather ask a basic question now than get this wrong quietly for two months.

Read the primary paper after arguing about the summary for a fortnight. The discussion section said almost the opposite of what the thread had concluded.

Spent an evening on the receptor distribution literature and the side-effect map suddenly stopped looking random.

Was completely wrong about the gastric emptying story in a thread here two years ago. Someone corrected me with a citation and I have not made that mistake since.

I will update this if the picture changes rather than quietly leaving it up.

GIP receptor biology is genuinely unsettled — there is a live argument about agonism versus antagonism at the receptor — and the clinical results are robust regardless, which is an uncomfortable and interesting position.

GLP-1 receptor agonism acts both peripherally — insulin secretion in a glucose-dependent way, slowed gastric emptying — and centrally, on appetite regulation. The central component is the better explanation for sustained intake reduction.

This is the concept everything else on this board is downstream of.

the peripheral and central stories are not in competition
