Koechlin doesn't eliminate any food group—instead, she makes sensible choices throughout the week and enjoys herself on the weekends. "I eat everything but mostly stick to vegetarian food on the weekdays and non-veg on the weekend," she says. "I find it hard to zone in on one favorite dish, I love mutton biryani. I relish a good fish grill in lemon sauce, palak paneer and baba ghanoush."

Koechlin keeps things interesting when it comes to her diet, thanks to her multicultural background. "I grew up in Pondicherry, so was closely associated with south Indian food," she says. "Our daily diet included rice, rasam and sambhar. And that's the reason I have always preferred rice over roti. As far as my association with French food is concerned, my mom is French, so she used to make homemade bread, apple pie and different types of salads. Probably this intermingling of cultures has made me so experimental."df44d9eab23ea271ddde7545ae2c09ec

Koechlin believes in portion control and enjoying everything in moderation. "Large portions contain more calories than small portions and we tend to eat more food when presented with bigger sizes," says Lisa R. Young, Ph.D., R.D.N., C.D.N. "Furthermore, the larger the portion, the more we underestimate how much we just ate. It's like the oversized meal (or snack) never happened. Portion control is, therefore, super important when it comes to managing weight."

Koechlin enjoys healthy snacks that are vegetable or fruit based. "It is really difficult to have a balanced and healthy diet while shooting or traveling," she says. "But as I have close association with the basic dal and chawal, so I make sure that my main course is around it and while shooting I often feel hungry so I balance the healthy side with nimbu pani, nariyal pani, fruit salad or mixed salad. All these snacks do not make me lazy and keep me active all day."

Koechlin prefers to exercise in fresh air over a gym. "Yoga is something I have been doing on-and-off," she says. "For me, it's swimming. Swimming and yoga. I am not much of a gym person. I don't like to build muscle, but yoga and swimming is what I do."
