Robert Lustig interview. 

I don't agree with all he says (particular about the carbon "problem" in the environment), but a bunch of the other stuff I think he has some good information.

Edit: I do not agree with everything Dr Lustig says. Come to think of it there is not another person on this planet who I agree with everything they say. Even my wife. Or maybe especially my wife, LOL. If I only listened to people I only agree with 100% of everything they say I not only would not and could not learn anything new from them, I just would not be listening to anybody. So the fact I do not fully agree with everything he says does not mean he does not get something or even a lot of things right. Or that I am not wrong in my thinking. At any rate I think he has some interesting comments and thoughts and is definitely a pretty smart guy with a lot of experience in his field. Outside his field........like anyone else........... he has opinions.
