New Delhi, Feb 10 (ANI): Jared Leto has admitted that he will never lose weight for a film role again after his extreme diet for ' Dallas Buyers Club'. The 42-year-old actor admits that extreme dieting began to ''take its toll'' on his body after he shed the pounds for his latest role as a transvestite, who is addicted to drugs and dying of AIDS. He told a magazine that he will never do it again, as it's a really hard thing to do to one's body and when it's done over a short period of time it's incredibly brutal.
