Same exact number with me under the same conditions.  So the theory is
that if you go zero carb, you'll drop your fasting glucose down to more
healthy levels.  But that didn't happen for me, even with zero carbs. 
That was a huge surprise.  How could it be high if I'm eating zero
carbs?  The answer is that I was eating high amounts of protein which
upon ingestion my body simply converted to glucose via gluconeogenesis.

That's why I believe you need to go zero carbs (less than 2% of calories
per day), moderate protein (76-108 grams a day is I think your zone),
and unlimited quality fat in order to budge that fasting glucose
number.  If you're northern European, at least, you spent the majority
of the year that way in nature.
