His shoot of the 17th century period drama Tanhaji: The Unsung Warrior behind him, it is time for Saif Ali Khan to switch back to present day. Before he begins filming Jawani Jaaneman — his first home production under the banner of Black Knight Films — the actor will apparently have to lose his muscular frame over the next five weeks for the Nitin Kakkar-directed venture. While Khan had bulked up last year for his Udaybhan Rathod act in Tanhaji, he is required to attain a lean frame for his portrayal of a 40-something father to Alaia Furniturewalla in the comedy.

In keeping with his practice of not having a dietician or trainer, the star, we hear, intends to achieve the feat without any aid. A source reveals, "Saif takes help from a few trusted experts from time to time, but he usually self-trains. He starts shooting for Jawani Jaaneman around mid-June. Since there's little time on hand, he has charted a no-sugar, low-carb meal plan. His breakfast will include oatmeal with skimmed milk, followed by fruits. He will restrict his lunch to a bowl of salad and dinner will consist of a light fillet steak. The diet will be supplemented by an hour-long cardio session, twice a day."

Furniturewalla, who makes her Bollywood debut with the movie, will join Khan for readings next week. "Before they leave for the 45-day London schedule, the director wants the actors' camaraderie to be fluid since the film centres on the father-daughter relationship." With Khan finishing the London leg only by July-end, buzz suggests that the promotions for the second season of Sacred Games may be pushed to August.
