Glucose, non-diabetics

The problem with "non-diabetic" is that in the modern age it increasingly only really means undiagnosed with metabolic dysfunction. There are millions upon millions of people who aren't diabetic simply because the diagnostic criteria of HbA1c is a bit rubbish. Quite often I see comments along the lines of "it's normal for non-diabetics to sometimes go to around 9 or 10."

Err. No. It's not. Not in any kind of normal prior to 1980.

Though there is no real data from then to back up that claim, just because its only recently where 24 hour monitoring has been available (to some)

@CallMeAlan if you want to have an idea of what happens to the blood sugars for people who have not been diagnosed with diabetes look like, Google will help you find Libre graphs from people without diabetes.
There are few around including students studying their blood sugars as a research project to elite athletes studying their levels to optimise their performance.
And, Yes, they may go lower than 4 and rise higher than 9 .. but return to lower levels quicker than you would expect from someone with undiagnosed type 2 (which is what most people call "undiagnosed with metabolic dysfunction").

Something I've been wondering is what the glucose readings would or should be for non-diabetics.

My own (T2) readings, averaged over 10 months are:

Morning : 8.1
Afternoon (about 4pm) : 6.3
Evening (2 hrs after dinner) : 6.5

Gross average, disregarding time of day: 7.05, lowest: 3.8, highest: 9.9.

I once took my non-diabetic daughter's readings at about 3pm and it was 6.3.

Would love to compare.

I might be able to help you soon as have just ordered my first glucose meter, having read so much helpful advice on this site. I am non-diabetic, as far as I know, as my last Hba1c over a year ago was 40. It is usually 39-41 and did once reach 42, so I am the high end of 'normal'.

What has always puzzled me, however, is that my fasting blood glucose has always been pretty good (around 4.5 - 4.8), so I am assuming my blood glucose gets quite high at times during the day to give me that Hba1c average. This is despite me eating a low-carb diet, so am just wondering where the it comes from!! Hopefully I will soon have more insight.
