Sanjay Dutt is high on ‘Panipat’ as he works relentlessly, preparing for the period saga. The actor plays the role of Ahmad Shah Durrani, the founder of the Durrani empire, for his upcoming film ‘Panipat’. To perfect his role, he has adopted a special diet which doesn’t include much carbs and fats but is rich in protein. With heavy costumes and intense action in ‘Panipat’, the actor is expected to maintain a strict workout regime as well. Getting into the skin of the character, Dutt had even shaved his hair off for his Afghan king role in the film, which is directed by Ashutosh Gowariker.
