Won't lose weight for role again: Jared Leto

After following extreme diet for "Dallas Buyers Club", actor Jared Leto says he will never lose weight for a film role again.

The 42-year-old admits that diet plan began to "take its toll" on his body after he shed pounds to play an AIDS victim and a drug addict in the movie, reports contactmusic.com.

"It does take its toll and it's not something I will ever do again. It's a really hard thing to do to your body. When you do it over a short period of time, it's incredibly brutal," Leto told Attitude magazine.

Leto's dramatic transformation won him a nomination at the 86th Academy Awards in the best supporting actor category.

"This time, I was playing someone who was not only addicted to drugs but also dying. When you lose weight it's not only about how you look, it's how it affects you as a person, and your performance , and it changes so much about how you are. The fragility that all provides was essential to the part," Leto said.
