Query: Good Diet, Great Profits

I think this is a good diet and a lot healthier than Atkins. His point of view as a heart doctor who was just trying to save his patients lives, not to create a popular diet, was refreshing - even if he did overdo it a bit. Apparently, however, he has gotten over any qualms he might have had about being part of the "diet industry" - with the over $20 per month web site membership and the endorsements of new "South Beach" Kraft products. (Why would Agatston want to partner with the maker of Kraft Macaroni and Cheese Dinner and Kool-Aid? What's next - South Beach Twinkies?) My faith is somewhat undermined. But I guess the fact that the good doctor has sold his soul for money doesn't mean the original diet is compromised.
