Jared Leto, like Matthew McConaughey, lost an incredible amount of weight to take on his role in Dallas Buyers Club.

Leto recently revealed that in order to play the HIV positive transgender woman, he lost somewhere between 30 to 40 pounds. “I stopped eating,” he told The Wrap, explaining how he got down to about 114 pounds. "It changes the way you walk, the way you sit, the way you think," Leto added.

The 41-year-old actor dropped the weight for no other reason but to better inhabit the role he was cast in, enduring the uncomfortable period of fasting for the sake of his character Rayon. “Your body goes through weird stages. Sometimes it’s hard to hold on to water, Leto told Vulture in November. “But for me, it’s not about the most weight I can lose; it’s more to represent the character. I’m focused on what it means to be a transsexual woman.”

Leto’s costar McConaughey lost about 38 pounds to play his character Woodroof, a homophobic man who has been diagnosed with HIV and is determined not to heed his doctor’s projection that he only has a month to live. Instead of following his doctors’ orders, he sets up the Dallas Buyers Club to sell HIV treatments he obtained llegally to those in need.

The Dallas Buyers Club recently screened at the Toronto International Film Festival. It’s slated to hit theaters Nov. 1.
