All I know is my spouse was diagnosed with Type II diabetes. The effects of it resulted in blindness which I hope can be restored. However the diet changed dramatically — no more sugar at all, and sever restriction of carbs. Now we both went on this diet — high fat, no sugar, low to no carbs. Both of us lost well over 50lbs, Myself I went from 230lbs to 165lbs. So I think even with our small sample size we’ve hit on something.
