YOGA

To play a "buxom and curvy" newlywed in the hit film The Help, the 5'4" vegan had to get creative about piling on the extra pounds. "I microwaved soy ice cream and drank it to get the calories up!" she says. Once the movie wrapped, the actress, 30, turned to yoga and healthy eating to shed the 15 lbs. she gained.
