Purely anecdotal, but interesting coincidence - walked with friend yesterday, and he knows someone who lowered their blood sugar permanently by doing intermittent fasting. This makes sense, since fasting moderates insulin resistance. There is an ok book about it by a liver/kidney doctor. Can find if interested, don't remember name offhand. I found it to be good even though I am obviously not a fasting fanatic.
