Aamir Khan has put on a lot of weight to play a wrestler in his next, ‘Dangal’. He has already shot for a major part of the film and will now start with the process of losing all the extra fat. “The initial 10-15 percent of the film has me playing a national level wrestler, like Sushil Kumarji. The old age and overweight portion is complete now and I have started losing my weight. My next challenge is to comeback in shape, like I was in ‘Ghajini’ and ‘Dhoom 3’,” says Aamir. For ‘Dangal’, Aamir Khan had put on 25 kgs, which he will now shed, to get a muscular and low fat body. He will then shoot for his portions in June.
