Anyone interested in good health and a good laugh... I have recently read Skinny Bitch and I laughed my ass off. There's an entire chapter on "poo"ing and they refer to soda as "liquid satan". "You are what you eat...so everytime you put crap in your body, you are crap." "Eat your fiber and crap like a champ!"
Their thoughts are blunt and possibly brutal but made me laugh hysterically.
Most of their suggestions yield a vegetarian lifestyle, so it may not be for everyone. But, for me it was a informative short book for a sunday afternoon.
