Rob McElhenney For It’s Always Sunny In Philadelphia
I know that this was for TV and not for a film, but there was no way I could make this list without including Rob McElhenney’s awesomely hilarious weight gain for Sunny. McElhenney gained a whopping 50 pounds in 5 months for the benefit of the show.
The actor didn’t decide to put on the weight as a plot device, but simply because he thought it would be funny. Naturally, quite a few episodes were centered around his weight, most notably How Mac Got Fat, but it was all for gaining a few laughs.
His diet consisted of 5 1,000-calorie meals a day. Originally he began by eating chicken and rice, but eventually he realized a Big Mac and donuts were much easier. Plus, what better way to make a bigger Mac than with Big Macs? (Sorry, I had to.)
Fans who have tuned in for Season 8 may have noticed something remarkable; McElhenney is back to his normal weight, and even a bit buffer than before. He lost 23 of the 50 pounds in the first month, and the rest came off shortly after.
