You have done brilliantly to get that very high HbA1c down to 44 in 6 months. That is excellent, but such a shame to put this at risk if you go back to old ways.
You are still diabetic, even though your current HbA1c is within the pre-diabetic range. An HbA1c of 44 is equivalent to an average of 7.3mmol/l so you are still spending a lot of time above 7.3. Why not eat a carby meal and test it out?
My HbA1c's have been in the prediabetic and non-diabetic range for 3 years but I know exactly what happens if I eat, for example a sandwich bun or a battered fish. If you start eating carbs again you risk getting back to diabetic levels. Pre-diabetes is an "at risk" condition. I have to keep eating to my meter and can't afford to become complacent. That isn't to say I don't experiment. I do, but then trust what my meter tells me.
