> better insulin sensitivity in the AM

I think it's more accurate to say "After a fast" .

Next study needs to shift these windows by 6 hours. I suspect it will show nothing to do with circadian rhythm and everything to do with fasting/non-fasted eating.

I don’t think After a Fast” is accurate in the context. ‘In the AM” is referring to the Dawn Phenomenon[0], isn’t it?

I'm lazy to dig it up, but there was a study comparing people skipping breakfast and skipping dinner. The conclusion was the insulin sensitivity was higher from AM - to early PM (breakfast + lunch), than from early PM - evening (lunch + dinner).
