    Another misleading FBG caused probably by physiological insulin resistance. In his case though, his is a bit higher and he's 50, so I would tend to think he's prediabetic. But you can recover from prediabetes, yes.

    Here's some good info regarding the A1C test from Chris Kresser:

    Why hemoglobin A1c is not a reliable marker

    tldr: A1C can be skewed high if your red blood cells live longer than average.

    Have you checked your numbers fasting, before your first meal and 1 hour post- and 2 hours post-prandial? Doing so can give insight to what's happening. If your numbers actually go down after you eat, maybe you should back off on the IF for a while or cut back on exercise somewhat to try to lower cortisol. If your BG goes really low in the post-meal window it could be reactive hypoglycemia. Lots of possibilities that checking with a glucometer could help figure out.

    Just want to point out that that is for a glucose tolerance test. An AIc doesn't require this since it's a 3 month average.

    Correct, just take HbA1c. You can buy a kit from Walmart for $9.99 and that's pretty reliable (I would add 0.2 to the result, however). If you're like 5.7-6.9, that may be considered "prediabetic" and you can recover doing low carb or moderate carb. Beyond that, I'm not so sure. We know it doesn't have an arbitrary cut-off point and is a continuum for each individual. Some really strict docs think even 5.7 is prediabetic.

    Yes, you are right. I was pointing that out as a possible explanation for why the results were so high. Perhaps there is no actual problem.

    Got a call from the Doctor's office and the result is 5.5. The print out is being mailed. Relieved and I have much to learn. Reading has started. I've felt better since going primal the past year. It's good to have hope the results can get better as I learn and continue on.

    Thanks everyone!

    Congratulations! You're well into 'safe' territory with anything in the 5s.
