"For the last two years, Matt has literally had to watch every morsel he put in his mouth. He's admitted to pals that he's sick to death of dieting. He says he wants to find a project where he doesn't have to count every single calorie. And if he can't find a project like that, Matt has said he'll take a break from filming. That's how serious he is," a source said.
The 42-year-old followed a strict diet while filming the Liberace biopic Behind the "Candelabra" and the upcoming sci-fi thriller "Elysium", reported Showbizspy.
