Understanding A1C | American Diabetes Association
When glucose enters your blood stream, it attaches to a protein in your red blood cells called hemoglobin. When you have higher blood glucose levels, there is a higher number of hemoglobin with glucose attached. The A1C test checks your red blood cells for the percentage of hemoglobin with glucose attached (glycated).

r/prediabetes on Reddit: Honestly what is a normal A1c? For non diabetic
October 21, 2022 -
My A1c was 5,5% a couple of month ago where I started to see I was insuline resistant so I’m probably lower now with all the effort I made (I need to check now for a new one) but despite from that what is a truly normal A1c? No way mine was normal despite being below the cut off… I’m aiming for 4,5/4,6% if I keep my diet I’m pretty sure it attainable but will I ever be considered like a “normal” non diabetic even though I work hard at it ? Trying to stay away from complications for the long term… (33F)

Aiming for an A1c of 4.5 to 4.6 is basically impossible even for someone not insulin resistant. That’s an average glucose of 82. Unless you’re gonna go zero carb carnivore I don’t see how it’s possible. I also don’t think extreme diets are sustainable-/ you need something you can stick to for the rest of your life. Not a year or 2.

Good question, I've seen data on 153 healthy non-diabetics that wore CGMs, their average A1c was 5.1% https://www.diabetes.co.uk/forum/threads/they-fitted-dexcom-g6-cgms-to-153-non-diabetics-to-define-normal-glucose-the-results-are-in.182221/ Problems is define healthy, it's getting rarer nowadays. The Dutch took a cross section of about 3,000 non-diabetics, all ages & all weights. Turned out the average A1c was 38(5.6%). https://www.diabetes.co.uk/forum/attachments/hb-copy-jpg.57027/ When 1/3 of the population is diabetic or pre-diabetic the bell curve has been pulled well to the right. Your aim for an A1c in the mid 4s may be too low, there is a J related risk for cardiovascular disease, seems to be a sweet spot in the low 5s for optimal health.

Recent studies have also demonstrated that an HbA1c threshold of 6.0% appropriately discriminates between diabetes diagnosed by OGTT-based methods and nondiabetic subjects [21]. Therefore, our results suggest that the introduction of an HbA1c threshold of 6.0% in screening for diabetes is ideally ...

The higher your blood glucose levels are, the higher your hemoglobin A1C level will be. And because a red blood cell lives for 3 to 4 months, an A1C level gives an average blood glucose level over a similar period of time.
