Aside from his superb acting in "Dallas Buyers Club" that earned him multiple prestigious awards, Matthew McConaughey attracted attention for his role on the film because of the noticeable change in his physique brought about by an extreme diet.

A previous report by Mirror tackled Matthew McConaughey's extreme diet that reportedly made him lose 7 lbs. a week for his role in "Dallas Buyers Club" which was filmed in 2012.

"I found tapioca pudding and I found the tiniest little antique spoon in New Orleans, a little bitty sugar spoon, and I would eat it with that so it would last longer," Matthew McConaughey said about the diet he employed when he was trying to lose weight for the role.

"Oh it was great in the morning when I would write from 4-6am with my tapioca pudding, I could make it last an hour ... It was tough going, I'm not going to lie. The dieting was pretty hard-core. I was losing 7lbs 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 [143lbs] 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."

More than a year after losing weight through an extreme diet, it seems that Matthew McConaughey still hasn't been able to being his old body back. And according to reports, the actor's wife, Camila Alves, isn't happy about her husband's current physique.

"Camila has confided to friends that if she had her way Matthew would have his bulk back. His career is on the rise so the beefcake roles are not the ones he needs to take anymore," an insider reportedly told Dish Nation.

"Camila loved the man that she first fell in love with and how his body was then. And while she still loves the man, the body has changed."
