Man of the moment, Jared Leto, says he will never lose weight for a film role again after his gruelling diet for Dallas Buyers Club.

The 42-year-old, who is up for an Oscar for his role as a transgender woman in the American biographical drama, said that he has no intentions to dramatically transform his body for a role in the future.

Speaking to Attitude magazine, Leto said: ''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.''

However, Leto also explained that he does not regret losing weight for his role as Rayon in Dallas Buyers Club, adding: "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.''
