I thought Good Calories, Bad Calories was very good. It's about the bad science behind the high-carb, low-fat diet advice. From there you can get into things like paleo diet etc. I'm not recommending any particular diet - there are plenty of people who think Taubes is full of it (http://reason.com/archives/2003/03/01/big-fat-fake http://www.proteinpower.com/drmike/wp-content/uploads/2008/0...), and I'm not a doctor and have no training in the field. Just an interested observer, since diet, nutrition, and exercise is the base for anything else you're going to do in your life.
