"I think that fashion is the healthiest motivation for losing weight" states Karl Lagerfeld, über-mogul and the creative genuis behind Chloé, Fendi and most recently, Chanel. He should know: the designer credits his now-svelte physique to a 90lb. weight loss brought on by a bizarre 13 month diet, the details of which he divulged to Dr. Jean-Claude Houdret and published in a self-named paperback.
The Karl Lagerfeld Diet explains the mental and behavioral causes of obesity before providing the reader with (seemingly) healthy weight loss tips and recipes. Oddly, Lagerfeld's own favorite diet snacks (horsemeat and diet Coke) didn't make it into the book...darn.
