There are posters on the McDougall forums who have put their Type 2 DM into remission and are off all meds after following that strict vegan diet--which centers on starches and allows no additional oils (the small amounts of fat allowed come from nuts and avos).

But I can't ignore the fact that there are people doing the exact opposite of what works for me--and it's working for them. I don't have the science background to figure out why, but it is. So I can't just write it off as vegan quackery, even though life as a fat-free sugar-burner didn't work for me. For the folks who have a truly lousy time of it on low-carb, it may be a perfectly viable option.
McDougall is one of the crazies, no basis at all for his recommendations.
Yeah, he's not somebody I'd want to take health advice from (as first I learned during my long-ago vegan phase). That he's an MD doesn't stop him from being a crank, and a petty, ill-tempered one at that. Some of the stuff he says (and that his followers defend) is so far off base and so wrong it's all I can do not to slam my phone/laptop down while shouting, "WHAT!" repeatedly at the top of my lungs. At the same time, I admit it's weirdly entertaining in a trainwrecky, reality-defying way. I read the 30BAD forums and conspiracy theorists for the same reason.

Remove the worst shit from your diet, and things do tend to improve, at least for a while. If diabetics are eating a lot of low-GI vegetables, that could do it, too. Weight loss from calorie restriction doesn't hurt, either. So I guess I shouldn't be all that surprised that going strict low-fat vegan can work for some T2 diabetics. But long term? I admit I'd like to see how those same low-fat vegan diabetics are doing with their successful blood sugar control (among other health issues) 5-10 years (or more) down the road.

I cannot live without ANY carbs at all, as I wouldn't have energy either just like Robb mentioned. There is a time and a place for healthy carbohydrates, and sweet potatoes are included in this equation.
