does incretin actually matter or is it forum lore at this point

Explainerbranch of 8 comments

The title is the whole question — does incretin actually matter or is it forum lore at this point — but here is why I am asking. Went looking for human data on a mechanism everybody here asserts. Found preclinical work and one small study. That was clarifying. Tried to build a mental model from mechanism alone and…

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.

Small fix — it slows gastric emptying, it does not halt it, and the distinction matters for the mechanism you are proposing.
