That's a new one hey?
Well, the reason I say it, and I'll keep this short, is that for any T2 diabetic (or T1 for that matter) to insist on eating carbohydrate as a main fuel source is that:
1. They like eating carbohydrate.
2. They don't want to change and will offer any spurious viewpoint to support their world view.
That's it guys. Carbohydrate is glucose, and glucose id NOT your friend!
