Jared Leto reportedly lost 30 lbs for his role as the emaciated side kick to Matthew Mcconaughey in his celebrated role in Dallas Buyers Club.

He got his weight down to an astonishing 116 lbs, which for a man of his size is dangerously low. He later confessed that he “basically didn’t eat anything” for a few months.

Like his famous co star, Jared wanted to totally immerse himself in the role and felt it necessary to see the changes in how he felt and acted by being so dangerously underweight. “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.”

As you can see from the picture, Jared has later transformed himself in the other direction to become grossly overweight for later roles.

Now 41, he states he has slowed down and would not consider such dangerous body transformations ever again…
