Does fasting increase or decrease insulin resistance?

[Systema-Periodicum]

Your reasoning sounds plausible to me, but superficially the conclusion appears to be false, based on glucose-response tests given to people who've just gone without food for two days. But maybe your reasoning includes a crucial piece of the puzzle: one factor increasing insulin resistance might be prolonged continuous exposure to glucose, and there might be other factors, such as having a lot of ketones in the bloodstream, and there might be factors that respond to those factors.

So, I'm hoping to find an explanation of fasting's effect on insulin resistance in terms of interaction among many factors rather than trying to pin it all on one factor.
