Thanks, I haven’t read that book, but I think I have seen a talk of his on youtube.
I’ve had periods of a year or two at a time when I follow a carbohydrates restricted diet and get plenty of exercise and that works very well. I get a1c results that are close to normal.
My problem is I love carbs, and do less well when I eat what I love.
Having optimum potassium intake and consuming foods with b vitamins help to process sugar.
