I would never put on 20 kilos and mess up my system because a role demands it. Hindi cinema doesn't offer you roles that get you an Oscar, anyway. Tom Hanks can do it in Hollywood; not us.
I can't let the baggage of my private life get into work. Artists are more fragile than normal people. But I know that I am a role model for zillions of people, so no matter how deep you are hurting, you need to come out strong.
I actually wanted to be a doctor. But doing all those horrid rat dissections made me faint. I studied science till the 12th standard and later took up commerce. I was planning to do chartered accountancy, but fate had something else in store for me.
In India, we kind of concentrate only on weight loss. I want to teach people that it is very important to be strong and fit, rather than just thin.
