[Explainer] delayed gastric emptying does most of the work people credit to the brain

Explainer

Genuinely asking, not being difficult.

Everyone in c/tapering repeats that incretin is important. I believe it, but I have never seen anyone show why, and when I search I get 19 threads of people agreeing with each other.

Is there a paper? Is there a measurement? Or is this one of those things that is true because it has been repeated since 2023?

I am not trying to be the "source?" guy. I would just like a source.

The half-life is 13 hours, which means week 13 is genuinely still ramp-up. Week 12 is steady state.

rodent receptor tells you what to investigate, not what to expect in humans

Is that mechanism or speculation?

Strongly agree. Central appetite is real but people overstate it.

Yeah, the incretin mechanism is doing the work here.

Stomach physiology changed when I moved up to 2.4mg. Gastric emptying lag is the whole story.

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

This is correct. Rodent data is investigational, not predictive.

do not extrapolate rodent data to human dosing without saying so

That is net peptide content, not purity. Different number, different meaning.

the half-life is incretin, affects steady state timing

u/plain_titration1 point·2 days ago

the 3-day half-life means week 3 is still ramp-up pharmacokinetically

Yeah, the incretin mechanism is doing the work here.

central appetite signalling is real but people overweight it
