I eat the right kind of food; have lots of water and no junk food. I sleep 6 to 7 hours, I work out, don't do too many weights, lots of flexing and swimming everyday. I ensure we have a gym where we shoot and being around happy people helps. It's very important to smile. A smile is always returned, that's the beauty of it. I use Clinique products, Mac products for make-up.
I eat everything, Non-vegetarian, vegetarian, ice-cream, anything. But I work out regularly and keep myself fit. You shouldn't starve yourself because your body is not used to it.
