If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way.

Careful with the causal language. Two things moving together in a period when five things changed is not a mechanism, and stating it as one makes the thread less useful to somebody reading it later.

That is correct as far as it goes, and here is where it stops going. Yes, and the corollary is less popular: if the reasoning holds, it also holds where it produces an answer we do not like.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

This is exactly what I could not find anywhere else. Sending this to two other people who asked me the same thing last week.

Adding the clinical framing, because it changes how the question reads. Worth answering the question that was asked rather than the one behind it. The narrow version usually has an answer; the broad version usually does not, and answering the broad one is how a thread stops being useful.

Reporting back.

Update — tachyphylaxis to the gastric effect, persistence of the appetite effect. Two curves, and I had been watching the wrong one.
