unpopular opinion: most of what gets said here about incretin is guesswork

Explainer Well Actually ×1

unpopular opinion: most of what gets said here about incretin is guesswork. Making the case below, and I expect to lose some of it in the comments.

Asked a question here that I thought was stupid and got three papers back. Best thread I have been in on this site.

Started reading limitations sections first. It has changed how much weight I give to almost everything posted here.

Went looking for human data on a mechanism everybody here asserts. Found preclinical work and one small study. That was clarifying.

Screenshot none of this. Read the whole thread, including the parts where I am told I am wrong.

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.

Long half-life in this class comes from structural modification that promotes albumin binding and resists enzymatic degradation. Weekly dosing is a consequence of the molecule, not a convenience decision.

dose response is not linear and nobody should assume it is

Retitled to distinguish preclinical from clinical, which the original ran together.
