The Skinny by Louis J. Aronne, MD

This book was recommended by online friends - I can't say I'll follow his diet plan, but the theory behind it is interesting. And something that you could actually put in everyday practice.

Aronne's weight loss system is all about feeling full - being satisfied, and not feeling like you're missing out. Generally, the guidelines require you to eat a quantity of the good-for-you, filling foods, then a quantity of the the better-for-you, slightly-less-filling foods, then finally you can eat the not-so-great stuff. Theory: you'll be less hungry by the time you get to the carbs and junk, so you'll eat less of them.
