That makes me so sad. I watched the show a few times, and I had hopes that he could make a difference. Sadly, it didn't work. I think we're stubborn and really like to eat what we think is good. It's hard to change habits and taste buds. I struggle with it daily (eating what I *KNOW* is healthy and semi-tasty vs. what I love to eat that is really tasty but bad for me).
He tried- I give him all the credit in the world for at least trying to make a difference.
