If you were looking for an explanation for the slender physique that Harvey Weinstein has been showing off in recent months, you needn't look any further than the back of weight loss guru Dr. Louis Aronne's new diet book, The Skinny, which arrived in bookstores this week. Harvey was kind enough to issue a surprisingly cheerful blurb: "Dr. Aronne's new book is the most informative and intelligent approach to understanding weight loss and gain. Starting with page one, you will immediately feel healthier and better off. A must-read!" (As for that last bit, you can probably assume the "must-read" is just a gentle suggestion. Unless, that is, you're one of Harvey's poor assistants, in which case you should interpret it as an order.) But if you're one of those people who's been coping with the absence of Project Runway by binging on ice cream—and you're not inclined to shed the pounds by following Heidi Klum's suggestion and stomping up and down outside Weinstein's house—well, now you have an alternative.
