Mila Kunis laments the effects of her 'Black Swan' crash diet

Mila Kunis lost 20 pounds to become a 95-pound waif in "Black Swan," and she admitted to "Harper's Bazaar" that since she returned to the world of the eating, her body has not been the same. "When I gained [the weight] back, it went to completely different areas." Mila said -- specifically, her hips and stomach. Actors notoriously shed weight for professional and personal reasons, like Taylor Kitsch losing 35 pounds in two months (a choice he describes now as "f----ing stupid") or Jonah Hill's widely-publicized weight struggles. The impact of rapid weight loss can be incredibly long term, deteriorating muscle, slowing the metabolism, and when you allow the weight back on, the lost muscle is replaced with fat. (F---ing stupid indeed.)
