'Size zero' has become one of today's most contentious phrases. To some women it's the Holy Grail, to be attained whatever the cost to their long-term health and even fertility. To others, it's the terrifying obsession of an influential few which will lead impressionable young girls to develop eating disorders.

People are meant to be a certain way, and I think it's terrible if young girls force themselves to be something they're not. I'm not naive. As a mother, it does worry me that young girls see pictures of celebrities like Victoria Beckham and Nicole Richie - who are both painfully thin - and think they have to be that way.
