Matthew McConaughey, 43, who stands 6 feet tall - shed a staggering 56 pounds for the role of real-life AIDS sufferer Ron Woodruff in his new film Dallas Buyers Club
. He said: "It was tough going, I'm not going to lie. The dieting was pretty hardcore. I was losing 7 lbs every week. I'd have a Diet Coke, two egg whites in the morning, a piece of chicken, then another Diet Coke. That was rough. I got down to [189 lbs] and I was always hungry, and irritable. My body resembled a little baby bird with its mouth open, crying, 'Feed me, feed me,' and you realize momma bird ain't going to feed you. It's hard." The role is a big departure for Matthew after making a name for himself in rom-coms and action films such as Ghosts of Girlfriends Past
, Failure To Launch
He claims he didn't feel "challenged" by
some of his previous romantic parts and so decided to take a break. He added in an interview with the Daily Mirror
: "I would never say I'm done [with rom-coms] but sometimes I felt less challenged than I should have and I think you need a healthy amount of pressure to progress. I don't think I'll go back there unless I find something that really turns me on. So I just sat back, spent time with the family, took some time out to get a little clarity. I was OK for money, paying the rent, putting the bread on the table. So I did that and what happened - I started to get a different call for different types of scripts."
