London Fashion Week has provoked yet another debate over size zero models. The media has gone wild; Miss England is too big to model, Lilly Cole has gained weight, Ballet dancers must maintain a healthy weight too ... and so on.

Lately everyone has been talking about the weighty issues of obesity and the importance of body image; even feminist India Knight has published a book about her recent weight loss. In today's G2 she states "It's not unfeminist to go on a diet".

Is she right?
