talking about that. I am extremely skinny and borderline diabetes. The only way I can survive is to eat a few tomatoes and cucumbers/day. This Barnard guy is full of it by saying you can eat oatmeal and burritos lol yea right, lovely advice to diabetic people. Simple carbs are the worst, vegan diet is a good idea, but you have to stay away from sugars, including fructose. This means, no grains, no potatoes, no rice and so on.
