Stephan has up a couple of follow ups to those studies I posted about the other day.
It's a really nice roundup of the whole thing, which you can find here and then here. Most interesting is that the Paleo diet seems to have cured Type II diabetes with 100% effectiveness, and it may not even be primarily the low carbs that did it, but simply the elimination of grains completely.
I'm becoming convinced of this view. It's the grains way more than the carbs. Perhaps my "cheating" by eating a potato now and then isn't even a big deal at all.
If I were a Type 2 diabetic, I'd sure eliminate all grains from my diet and see how things go. By going this route and eating your other carbs (fruits and vegetables), you could avoid some of the problems with ultra-low carb while still remaining on insulin therapy, but of course, anyone ought to check with their doc. On that subject, Jimmy Moore has provided a wonderful resource in creating a blog to list doctors who specialize in low-carb dieting. They're listed on the right sidebar, by state. If you're diabetic and your health insurance doesn't have a low-carber you can consult with, then do yourself a big favor and consult with one of these guys out of your own pocket.
Just do it.
