1) Yes, if overfeeding or fasting insulin can dynamically change, but from my own high frequency testing it doubling *for no reason* under baseline conditions (unless already very low)- https://twitter.com/tednaiman/status/1293353143938379776">https://twitter.com/tednaiman...

-would be something I& #39;d find a little odd. Certainly there& #39;s a chance someone may have indulged more than usual right before the test, and that question is worth asking, but I don& #39;t think it warrants dismissal from that assumption alone. Many, many, many tests fluctuate rapidly-

-in the space of a few days if overfeeding/fasting. But people don& #39;t usually do this right before a test, and fluctuation while eating normally (in myself at least) I haven& #39;t seen huge unexplainable swings for no reason. A couple points up or down, maybe.

Lastly-

I would argue the opposite. I would much rather be obese with fasting insulin <10 than someone skinny with fasting insulin >10 (assuming eating normally before the test). TOFIs do exist and it is very possible to be hot while naked and hyperinsulinemic, or on the way there.
