I hate going out for lunch during a workday because it slows down my pace and ruins my rhythm. I prefer to eat at my desk. Actually, I wander around the design studio with a plate in my hand as I dine on, for example, salmon sashimi and a salad of tomatoes and mozzarella. I often have a bit of dark chocolate after lunch.
I had just 15 days to work on my body for the climactic fight of 'Bodyguard.' And I would work on every muscle of my body two/three times a week. I would have developed a superb body if I had three months, but squeezing it into 15 days can be harmful. Also, as you grow older, your metabolic rate slows down.
