My understadning is that A1c is indicator for average BG over some time like 3 months. I'd continue to avoid GPS (Grains, Potatoes and Sugar) as well as follow your physicians advise. Let them know you are going to try low carb as that may affect the amount of meds you'll need. We're not doctors here, at least I am not - so take heed. You're doctor was right in suggesting diet and lifestyle changes - but that depends on what those were. Can you explain what she said to change?
