the gastric emptying thing finally clicked for me and I want to write it down
the gastric emptying thing finally clicked for me and I want to write it down. Change my mind, genuinely — I have no stake in being right about this.
Tried to build a mental model from mechanism alone and produced a confident prediction that the trial data flatly contradicted.
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.
That is everything I have. The rest is opinion and I have tried to keep it out.
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.
[removed by moderator]
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.
read the discussion section, that is where the honesty lives
Cosigning on GIP. The genuinely interesting thing is that the biology is not settled and the clinical result is nonetheless robust.
Cosigning on GIP.
Disagreeing with this specific inference — that is a preclinical result being read as human pharmacology.
That conflates receptor affinity with clinical potency. They are related and they are not the same thing.
Left up and flaired Explainer. This is the standard of post the board was created for.
Careful — you have a plausible mechanism and no evidence that it is the operative one in the case you are describing.
Yes. The discussion section is where the authors say what they actually think, and almost nobody here reads it.
Tolerance to the gastric effect develops with continued exposure while the appetite effect largely persists. That single fact explains most of the "it settles but it still works" pattern the side-effect board reports.
Is there any human data on that mechanism yet?
glucagon agonism sounds paradoxical until you read the energy expenditure work
Are we talking about receptor affinity or clinical potency?
That study was in a rodent model. Worth stating, since the thread has been reading it as human data.
