Aamir Khan is a fitness freak. But the star is known to mould into any role he does and no wonder he got into the 8 pack body for Ghajini in a very short time. He had lost of weight for his role of Rancho in 3 idiots and post the finish of the shooting of the film he had picked up 8 kilos. So now the actor is back to a strict diet to lose weight and get fit and this time around he is on salads and fruits only.
