Marinating a1c below 5.7 is really hard for Diabetes patient. I was able to control it under 5.7 for few years but then it shoot up to 6.3. The main reason is my casual behaviour towards diet and weight.
The ADA guideline of 5.7 was challenged by American College of Physicians (ACP), they have there study which says:
