I have been Paleo for over 3 months now. Was told I am 'pre-diabetic' so I have started testing my blood glucose levels recently. What I have noticed is my morning levels are usually around 90 (approx 6:30am) but 5-6 hours later (approx 17 hours fasting), after having nothing but water my levels are usually around 110. Not a huge increase but my understanding was that during IF blood glucose should remain low and relatively constant. Anyone have any comments or ideas?

I think it is all the above, as nasty brutish suggested. We're hard wired to survive... peripheral insulin resistance protects organs during starvation while still feeding the brain glucose.
Extended starvation causes DIABETES and so do yo-yo diets, 'hibernation states' just as much as over high carb diabetic diets...
This explains the phenomenon: Starvation diet and very-low-calorie diets may induce insulin resistance and overt diabetes mellitus. Koffler M, Kisch ES.

I don't have the PDF, but I'd love it. :)
I've only recently began experimenting with intermittent fasting but I've had similar results. My blood sugar remains within a fairly narrow range for the first 18 hours or so but starts shooting upward at around the 20-hr mark.
I haven't determined the exact cause but it could be due to gluconeogenesis, cortisone, norepinephrine, etc.
