Normal is normal. If you're diabetic and your Hba1c is over 41, then it's not "normal", it's diabetic (or pre-diabetic, but that's NOT normal). Often diabetes nurses talk about lowish levels being "normal" for diabetics, which in a sense they are, because if you follow the NHS guidelines, that's what you will have. If you want to get your levels back to real normal, and not diabetic levels, then follow the low carb programme, and you will get them back to normal. Thousands of those of use who follow a low carb regime have reversed their diagnosis, and got levels under control (mine were 68, and now 32).
