Matthew McConaughey has revealed that he found the dieting for his new movie Dallas Buyers Club as 'tough going'.
McConaughey is set to play Aids victim Ron Woodroof in the Jean-Marc Vallée directed movie.
The Magic Mike and Killer Joe actor lost almost three stone for the role - which could well be the most successful of his career.
Speaking to the Daily Mirror the actor said: "It was tough going, I'm not going to lie. The dieting was pretty hardcore. I was losing 7lb 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," he explained.
"I got down to nine-and-a-half stone 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 realise momma bird ain't going to feed you. It's hard."
The true life story sees Jennifer Garner and Jared Leto also on the cast list.
But before we see McConaughey in Dallas Buyers Club he will be back on the big screen next month with Mud - a movie that sees him team up with Reese Witherspoon.
