[Admin note: I've (obviously) shifted this conversation about HbA1c from its old home in the thread about best biomarkers to a new thread dedicated to the topic, since I think it is of general and lasting enough interest to deserve it's own thread.]
Has Lustgarten mentioned his fasting glucose / post-prandial glucose / A1C% targets? I've been curious what others are setting for a goal in these areas. Last I checked, my A1C measured 4.9% on a low-carb diet (down from 5.3% on a higher carb diet), although I'm not sure if lower is continually better or if there's some optimal U-Curve there (beneficial hormesis?)
