Kate Moss was accused of giving the wrong message to anorexics and teenage girls when she gave her backing for a slogan encouraging them not to eat.
Interviewed by fashion industry website WWD about her favourite mottos, Moss said: "There's 'Nothing tastes as good as skinny feels'. That's one of them. You try and remember, but it never works," she added."
Campaigners said Moss, 35, who has a seven-year-old daughter, risked creating eating disorders in girls and young women. Beat, a charity for people with eating disorders, said: "It's very unfortunate that someone who is a style icon would make such a comment. We can only think and hope that she wouldn't realise just how dangerous it could be.
Many models have slammed Kate Moss's remarks saying: "Young people struggling with an eating disorder are fighting a tough enough battle as it is, without thoughtless remarks such as this which can make it even harder."
The fashion industry has been criticised for using so-called "size zero" models -- those who fit a US size zero -- particularly after the deaths of two South American women who had suffered from eating disorders. A report on the health of models in 2007 resulted in a ban on girls under 16 taking part in London Fashion Week.
However, Britain stopped short of measures taken in Spain and Italy, where models with a body mass index (BMI) below a certain level are barred.
