Hi ziggy_w
thanks a lot. This is very useful.
Do I understand that CGMs are the metres, e.g. Dexcom G6, which measure just beneath your skin?
For illustration Hb1Ac measurement of 53 mmol/l corresponds to a CGM of 160 mg/dl on average.
The plot contains 95% intervals, but even if I eyeball a 67% interval (1 standard deviation)
you can get a variation of Hb1Ac values about 6 values up to 59 and down to 47 which also will
give CGM of 160. This is quite scary for two reasons.
1) When people fret about being below the diabetes threshold of 42, they could be off by a huge margin.
2) I would be surprised if all GPs know that there can be such large discrepancies between Hb1Ac and CGM.
I also read that for individuals the Hb1Ac variation is much more stable.
Thus I have to accept that for me the rise from 42 to 55 is real. Maybe Christmas where I did not resist sweets (which I usually do) and also not fast had a bigger impact on my Hb1Ac.
You are eating oats and fruit and not testing your response to them?Thanks for the info.

Breakfast is typically home-made muesli based on oats, some fruit and full-fat yoghurt. I now can't eat whole grains (more like whole sugar) anymore.
Thanks to losing 10 kg my Hb1Ac reduced to 42mmol/mol on 28 Nov 2019.
I agreed with my doctor to come off metformin (2x 1g /day) in mid-Dec 2019.
After some questions on this site @Bluetit1802 said she tested on another assay, which produced a lower result. I did 2 tests at Medichecks, one assay was the same type my hospital uses and the other was another type @Bluetit1802 mentioned. The first test was the same result as my Doctors test, the other was 4.5 mmol/L lower.
If I had to hazard a guess as to why your A1c has drifted up a bit, I would likely put my bets in the folowing order:
- easing off a bit over the festive period
- your exercise regime changing due to your shoulder situation
- stopping your Metformin
Thanks a lot for this info. This confirms what I thought.
At this time I can see no reason to go back to Metformin,
I will need to find a way to exercise despite the shoulder pain, if it persists.
Regarding diet, I hope to make the weight loss permanent at the end of November level,
i.e. lose another kg, but I seem to have reached a limit in that I need the fast days
just to stay put.
Weight loss is no bad thing, but you might be giving it far too much credit for lowering your HbA1c.
So you cut carbs to lose weight, how can you differentiate which part of that equation resulted in lower bgl? There are studies that show if you cut carbs without losing weight then bgl still improves.Thanks a lot. I "disagree" with your literal statement, my Hb1Ac was lowered by losing weight. However we very likely "agree" on the principle. Of course it is the carbs. I lost my weight by eating no carbs for twice a week (5+2 see books and videos by Michael Mosely) and I am eating smaller portions of carbs on normal days. Reading the book "The Diabetes code" by Jason Fung and watching lectures by him and others, confirms that Diabetes and being overweight or obese go hand in hand. Sugar/carbs is converted into fat in your liver. If you eat too much of it, this makes you fat and causes insulin resistance and Diabetes type 2. This needs to (can) be overcome by changing your diet. Sugar/carbs must be reduced and/or temporarily removed.
If you eat too much of it, this makes you fat and causes insulin resistance and Diabetes type 2.
Did you do the same for carbs and bgl though?I don't know why we are arguing. It seems that what worked for you is different from what I experienced. I log the data and observe a linear correlation between my blood sugar and weight measurements, which I consider meaningful.
I found a similar result where Newcastle was 2 pts lower than Carlisle, measured in same week.Yes indeed. After a couple of years of HbA1cs considerably higher than my own comprehensive data from frequent finger pricks, A1cNow and the Libre suggested, my GP went to great lengths speaking to the Consultants at 2 different labs that use different types of machinery for HbA1c testing, and arranged for me to have it tested at both these labs from the same blood draw. The new lab returned a result 4mmol/mol lower than the usual lab. This has now been done 3 times and produced the same difference.
I really can't agree with the statement about too much carbohydrate making us fat and type two - it is the inability to deal with the carbohydrate we are advised to eat which is the problem for me
No it is the reverse - being pushed to eat more than the amount of carbs I could cope with made me fat - I should never have allowed anyone to dictate what I ate.Isn't that the same thing? Also, I think it depends on the individual. I obviously can't deal with the recommended amount of carbohydrate (too much carb) whereas my wife can't cope with less than the recommended amount of carbohydrate. When I say can't cope I mean she will go weak and wobbly, almost like a hypo . . . almost.
Pushed? I'll say that the advise is wrong it doesn't apply to everyone. My wife doesn't have to worry about the carbs she eats.being pushed to eat more than the amount of carbs I could cope with made me fat
