My parents didn't overfeed me, nor did they make an issue of it. That's when things go wrong. It doesn't have to be a problem for children to be fat, but it does affect you: you aren't as happy in that skin.

I was doing a show at the National Youth Theatre, playing an old man. Before that I had played fat clowns and I thought, 'If I want to have the career I would like, I am going to have to lose weight.' I was just starting drama school, and found I was moving around a lot. I also started to eat sensibly. The weight just dropped off.
