If you look for more references and science debate, I suggest 'Good Calories Bad Calories' from Taubes. 'The Primal Blueprint' has some references but it is more focused on the practical matter. I can say that it worked very well for me and 2 other friends that tried it.

If you want to go old school you can check out the Hacker's Diet (free online, and recently got an epub version): http://www.fourmilab.ch/hackdiet/

After a lifetime of thinking that diets had to be permanent and results were only possible through hours of exercise this book turned me around. I lost 50 lbs in eight months and haven't looked back.
