Although I consistently eat low carb and see low numbers in blood glucose terms, my Hba1c doesn't go down. I got 41 eating 50 gm of carbs each day, then 42, lowered my carb intake to 40gm a day to try to go lower, but the needle is stuck I think - after all the bombardment with high carb, low fat low calorie diets over the decades, I think something is broken and I'll have to put up with it unless something does eventually come right, or I take up some really energetic exercise, which I can't really see happening. I do use my trampoline, but it is obviously not strenuous enough.
