Barton: 'I don't do crash dieting'

Mischa Barton has dismissed speculation that she is too thin, insisting that she does not diet.

Speaking to OK!, the former OC actress revealed that she preferred to stay in shape through exercise.

"I don’t do any crash diets," she said. "There’s nothing that I really do like that, because I’m always working.

"I mean, before I go do a film, I do workout more. I do get ready for a film and try to be healthy and in shape. And when I’m not working, I do less of it."

Discussing her favourite way to keep fit, Barton admitted that she was "obsessed" with pilates but added that she concentrated on "more cardio" to boost her energy levels when she was filming.
