Anna Faris had a very strict diet and exercise regime to get in shape for her latest movie House Bunny. She had to drop ten pounds and decided to ditch her body double for the movie and film all the scenes herself.

How did Anna Faris Workout?

“I think I was the last woman in Los Angeles who hadn’t done Pilates,” says Faris, who finally tried the workout- “It really changed my body!” Starting about six weeks before filming, Faris worked with her trainer and pilates instructor, Nicole Stuart, six days a week, ran a minimum of three miles per day and maintained a very strict diet.

What did Anna Faris Eat?

“You know how you read that all of these actresses eat nothing but chicken and steamed vegetables to stay so thin, well I had to do that,” Faris says. “I would watch the other girls loading up on fries at craft services and be snacking away on a piece of celery.” Since filming wrapped, Faris has eased up on her diet and exercise routine. “I could never maintain that,” she says. “Nor would I want to!”
