Bionic Woman's Weakness Is Chocolate

British actress Michelle Ryan struggled to shape up for her role as the Bionic Woman - because she didn't want to give up junk food.

The 23-year-old, who relocated to Hollywood to take on the physically demanding role, has been banned from eating pizza, chips and chocolate.

She says, "I don't need to be a size zero. I really love my food and would be miserable without it."

"I'm already in trouble with the stunt team on Bionic Woman because I keep sneaking chocolate on to the set."
