I read an article in the NY Times yesterday about the "Skinny Bitch" books. I had never heard about them, but they sound like a fun read- and they debunk those MYTHS about low-fat and low-carb diets. (Yes, I think they are myths). They are militantly in-your-face vegan points of view, but they seem to provide some brutally pragmatic advice about nutrition, the politics of diet and, of course, the meat industry. I'm not on any diet, nor do I need to lose weight, but I may pick these up just as a fun, informative read.
