Jared Leto "I Basically Didn't Eat"

Jared Leto hits the red carpet at the premiere of his documentary Artifact held at the Paramount Theater during the 2013 SXSW Film Festival on Wednesday in Austin, Texas.

Jared Leto then attended the Samsung Q&A and after party for the documentary, which is about his band 30 Seconds to Mars‘ legal battle with music label EMI.

Jared also opened up about losing about 30 pounds for his role in Dallas Buyers Club.

“I got down to 116 or something,” Jared revealed. “”I just basically didn’t eat. I ate very little. I had done similar things with weight, but this was different. I think the role demanded that commitment… It was about how does that effect how I walk, how I talked, who I am, how I feel. You know, you feel very fragile and delicate and unsafe.”
