Yesterday, Hugh Jackman tweeted to his nearly 3 million followers "If the bar ain’t bendin, then you’re just pretendin," and posted a photo of himself deadlifting 400 pounds. Of course, had Hugh read this article posted on Buzzfeed yesterday titled "The Cost of Becoming a Superhero," he might have tweeted, "If the bar _is _bending, then you soon may be experiencing renal failure." Turns out the insane 5000-calorie diets and intense two-a-day workout routines that actors like Jackman put themselves through to become superheroes are pretty bad for their long-term health.

According to the article, too much protein brings a lot of nitrogen into the body, which, with a healthy set of kidneys is eliminated in the form of uric acid through the urine. But as Thomas Sherman, a nutrition professor at Georgetown University quoted in the article points out, "When you start getting older or when you have some other kind of issues associated with your kidneys, you can run into a real risk of damaging your kidneys or renal failure." Other potential problems apparently include injury from over training and loss of skin elasticity due to changes in size, i.e. welcome to man-boob city. As Tom Hardy told Vulture.com last year about his bulking up for The Dark Knight Rises, "Shifting your weight fucks up your liver! You’ve got to be careful. It’s the end of that for me." So maybe it’s time to take a page from Tom Hardy’s playbook Hugh Jackman. We’re fans of you here at GQ, and we certainly don’t want to one day see Wolverine with man-breasts and a dialysis machine.
