Mac's 50 Pound 'It's Always Sunny In Philadelphia' Weight Gain: Charlie Day Explains

Now that the internet has been treated to the first glorious photos of "It's Always Sunny In Philadelphia" star Rob McElhenney's more than filled out body, carrying a hilariously noticeable 50 extra pounds, it's time to find out just how he attained such an impressive body change.

Luckily, it seems pretty attainable for those aspiring to be just like their wildly scheming, dive bar-owning hero.

"A lot of protein shakes filled with ice cream. And doughnuts," was the simple diet McElhenney adhered to, co-star Charlie Day told NY Mag's Vulture blog. But the way Day sees it, this was inevitable -- though, of course, it's all being hastened for comedic effect.

"Well, you know, the reality of a guy who lives a lifestyle like this character, who owns a dive bar, is that he would start to go downhill at some point," Day said. "We wanted to have a new, fun direction for his character to go. We knew that 'fat equals funny' isn't good enough. It had to be like his character, specifically, because his character is just that into physical fitness. Actually, it would have been funny if Dennis [played by Glenn Howerton] had done it, too."

True, while fat equals funny may not sustain an entire season, the photo below, well, does induce a chuckle for those well-versed in the show.
