I read both CAD and CALP. I preferred the CAD book, because it explained the science behind why the WOE works a little better for me. I don't do strict 1/3, 1/3, 1/3, BUT eating 2 cups of salad is a fantastic idea. Doing that keeps me from binging. So after the salad, I just end up eating what I'd like, but less of it.

I think reading both books is a great idea, then just figuring out what works best for you.
