Charlize Theron gained 30lbs for ‘Monster’, the movie role that showed audiences Theron was far more than a pretty face. Charlize Theron’s weight gain for Aileen Wuornos, the real life serial killer she portrayed, showed how committed she was to the role and her position as an actress in Hollywood.

Charlize Theron’s diet, and that word is used loosely, for her role in ‘Monster’ consisted of donuts and potato chips to pack on the 30lbs needed to look more like Wuornos. It wasn’t the first time she put herself through dieting of some kind for a role – though the actress did the opposite when she portrayed a dying woman in ‘Sweet November.’

However, Theron has said that getting “fat” wasn’t the actual goal in her makeover for Wuornos, who she says wasn’t fat at all. It was more about lifestyle, letting herself go so she could get closer to the place Wuornos was physically.
