Kareena Kapoor is shooting at Pangong Lake (the world's highest lake at 14,256 feet above sea level) in Kashmir for Raj Kumar Hirani's 3 Idiots. While the rest of the unit members have been feeling dizzy and weak because of low oxygen (due to high altitude), Bebo is fighting fit thanks to her special diet.

The actress has been eating according to a diet prepared by her nutritionist Rujuta Diwekar. Kareena says, "It's tough working in extreme climactic conditions. Fortun- ately, I am surviving because of my yoga and diet, which I change according to the climate of the area where I shoot." Last year, the schedule had got cancelled because of bad weather.

Rujuta reveals her star client's secret recipe of looking great and feeling fit, "I had given her a diet rich in carbohydrates as Pangong and Ladakh are low in oxygen. Carbs give oxygen and allow her body to burn fat. Also the shooting is hectic, so she needs her calories. Kareena is eating the local staple diet of the Ladakhis — Thukpa (noodle soup), goat cheese, momos, and Leh berries (made from the juice of seabuckthorn, which are rich anti-oxidants and good fat burners." The actress also has lots of Ladakhi butter tea — which keeps you from getting dehydrated.
