My goal? To test out every diet and exercise regimen on planet earth and figure out which work best. I sweated, I cooked, I learned to pole dance. In the end, I lost weight, lowered my cholesterol and doubled my energy level. I feel better than I ever have.

I tried the paleo diet, which is the caveman diet - lots of meat. And I tried the calorie restriction diet: The idea is that if you eat very, very little - if you're on the verge of starvation, you will live a very long time, whether or not you want to, of course.

Exercise is more important than diet for me because it's a twofer. It keeps me in good physical shape, and it relieves stress. And when you're a representative of the public, there's never a shortage of things to do.

I honestly don't diet or work out regularly. I'm just always running around - you'll never catch me having a day on the sofa.

The majority of my diet is probably vegetables, but I'm not a vegetarian or vegan.

My diet is mostly composed of whole-grain cereals, legumes, beans, lentils. Lots of cooked, baked, or steamed vegetables. Lots of spices like curcumin or cumin that help aid digestion. Some superfoods.

It's never been an issue for me - I don't want to go on a diet, I don't want to eat a Caesar salad with no dressing, why would I do that? I ain't got time for this, just be happy and don't be stupid. If I've got a boyfriend and he loves my body then I'm not worried.

I went on a diet after 'Daawat-e-Ishq.' It was tough to resist eating because we were in Lucknow and Hyderabad, and the food over there is amazing.

I never grew up on a staple diet of Hindi cinema. In fact, when I was a VJ, I was averse to it. Purely because I could never imagine myself being an actor.

The dos are drink lots of water, get enough fibre and carbs as well, as they are important. The don'ts are don't be too extreme with any diet; it can really end up harming your system and immunity.
