Here is the bit where she talks about it. Read the whole interview at MM
People believe that you have become anorexic...
Rubbish. I am very tall. 5’ 9” to be precise. This means that if I really put on weight, I shall start looking like a giant. I don’t have the tendency to put on weight. (Pauses)
After seeing me in Rab Ne Bana Di Jodi, people got the wrong impression. In the film, they made me look bigger. I have always been a lean girl. And for heaven’s sake, I am not anorexic. Anorexics eat so little. Watch me eat and you shall know (laughs)!
What about you being sub-size zero?
That is the most ridiculous thing I have ever heard. There is nothing known as size zero. I am a size 8, UK. To call me sub zero is ridiculous. 8 is a very healthy size. Being skinny is not a compliment for someone who wants to put on weight, it’s frustrating. The world is obsessed with being overweight. If you are happy the way you are its fine.
