I have all the Covert Bailey "Fit or Fat" books and I still refer back to them for reference on body fat composition and assessments. I've read all of the South Beach Books. Also Gina Kolata "Rethinking Thin" and "The Low GI Diet Revolution". I love Gary Taubes' "Good Calories, Bad Calories". It really opens your eyes up to the faulty assumptions that bad research can make and what it takes to change the conventional wisdom out there. I really want to read "The Longevity Diet" after watching Oprah on Tuesday. Not a diet book, but has anyone read "Deadly Feast"? Makes you want to grow your own produce and raise your own livestock. A real eye opener. Love all the "You" series by Dr. Oz. I also like anything by Dr. Pamela Peeke (Fight Fat after Forty) and Dr. Andrew Weil.
