cary - I don't read weight loss books, so I don't know who said that. Sorry I couldn't help.
I wanted to comment on the D'Adamo book where he recommends eating for your blood type. My diet would consist of lots of meat apparently.
I only eat chicken and a few fishies that taste good to me. I can't imagine cutting down on veggies like he suggested. What the ****? I think he just hopped on the "I'll write a weight loss book and hope it sells like crazy so I can get a house in the Hamptons" train.
