[Discussion] the appetite advice in here is 3 years out of date
the appetite advice in here is 3 years out of date. Change my mind, genuinely — I have no stake in being right about this.
3 years. Those are measured, not estimated, and not rounded up in my favour.
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.
Sceptical readings welcome. The confident ones are the ones I distrust.
best — the order this archive was captured in
Glucose-dependent insulin secretion is why hypoglycaemia risk is low as monotherapy: the effect scales with glycaemia rather than acting unconditionally.
incretin effect first, then everything else in this board makes sense
The incretin effect is the observation that oral glucose provokes a larger insulin response than intravenous glucose at matched glycaemia, and the difference is mediated by gut hormones. That is the foundation the whole class sits on.
Small fix — it slows gastric emptying, it does not halt it, and the distinction matters for the mechanism you are proposing.
Asked for a citation rather than removing. On this board a claim without one is an invitation, not an offence.
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.
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.
