My last HbA1c was just over a week ago and was 34.
From my understanding the brain still needs some glucose as well as ketones so the PIR happens when glucose is scarce (ketogenic diet) and the PIR is the body's attempt to spare the glucose for the brain only rather than the muscles which can use ketones. I think.This PIR has me baffled. The brain runs quite happily on ketones so does PIR happen when glucose is low as well as ketones? What am I missing?

Well done on getting your HBA1C down, sometimes we see changes on our meter that just can't be explained.
Please remember that changes in health, stress, sleep and exercise (even a different batch of test strips) can make a difference to our readings.
Thank you. So that is when there would be some serious gluconeogenesis in the case of a starvation diet re proteins.
Edited to add. This is like belt and braces for the brain re fuel.
It was suggested that perhaps I had a few more carbs for a couple of days but cannot work out if this would send my BG higher or whether this would put things right or what?
I have tried a couple of short fasts i.e. 4pm till 11am next morning and although the morning reading went down slightly, it was straight back to 120 the following morning. I have wondered if I am having too much protein?
Fasting isn't a good idea for my metabolism - it caused my BG to rise higher than I'd seen, and also drop lower, and that was just not eating in the morning but waiting until midday.
That the brain requires glucose might be true - but it is not an argument for eating carbs - the liver can release glucose as needed for preventing hypos, though its capability is reduced by taking Metformin - why that should be a good thing I cannot yet understand.

If it is PIR then cutting the carbs even further is likely to make it worse as there will be less glucose available for the bits that need it, so there will be more resistance in order to spare it for those bits. Increasing carbs slightly may increase levels but only during the period of increase, and thereafter they may return to your expected normal. Or that is how I understand it.
I recently read something claiming that whilst most of the brain can function on ketones, some parts of the brain can only run on glucose.
Don't know if I can find it again (or even why I was reading it !) but I'll post a link if it turns up.
Hi do you keep a record of the amount of carbs you are eating? I could not find it in your earlier posts.
I would be careful about restricting protein, it is so important for the body repair process.

Perhaps I can save you some reading on this one.This PIR has me baffled. The brain runs quite happily on ketones so does PIR happen when glucose is low as well as ketones? What am I missing?
