Fab to Flab6 Hollywood Guys Who Went From a Six Pack to a Beer Belly!

Christian Bale

Few stars are as dedicated to their craft as Christian Bale.

He got in tip-top shape for American Psycho, only to drop to an impossibly frail-looking 121 for The Machinist. He bulked up again for Batman Begins, only to shed the weight for The Fighter before reprising his role as Bruce Wayne.

But the transformation that seemed to last with him is the weight he put on for American Hustle, which required him to gain 40 pounds.

Leonardo DiCaprio

Leonardo DiCaprio’s weight has fluctuated a lot with each role that he’s taken on. He admitted to packing on the pounds for Gangs of New York and had to keep them on longer than anticipated after the filming got delayed.

Then, he slimmed down again for Catch Me If You Can—but it looks like the weight finally caught up with him!

Will Smith

Will Smith is incredibly fit and knows how to get in shape—as seen in his roles in I, Robot, Ali and I Am Legend, among others.

However, in recent years, it seems like the father-of-3 has gone from “Parents Just Don’t Understand” to looking exactly like someone your parents would be friends with. And likely understand, quite well actually.

Channing Tatum

Channing Tatum’s washboard abs used to be the perfectly sculpted body of every woman’s dreams. These days? Not so much… but don’t blame him—blame his daughter, Everly, who turned one just last month!

He packed on a few pounds when he took off work to spend more time with his wife and child—but he doesn’t regret a thing.

“Me and my wife like to say I am very fappy: I’m very fat and happy right now,” he joked with Ellen Degeneres.

Rob Kardashian

For months, Rob Kardashian has publicly struggled with his embarrassing weight gain.

The 27-year-old was forced to face the biggest reality check when his mother encouraged him to visit a doctor, and his blood work came back with troubling news.

“It’s a shock to me. I was at my best health at 26 and now I have numbers that are freaking my whole family out,” he confessed on Keeping Up With the Kardashians.

“My dad passed away super early, so my sisters could never handle that again with me. That’s what everybody is super concerned about.”

The reality star has since worked on getting back in shape with trainer Gunnar Peterson.

Mark Wahlberg

Mark Wahlberg’s body has changed a lot since the days he sold underwear as the sexiest Calvin Klein underwear model we’ve ever come across.

He beefed up—to the tune of 12 meals a day—for his role in Pain and Gain, but has since dropped the weight, shedding 40 pounds for his part in The Gambler.

Much like the Funky Bunch, it looks like his once incredibly impressive physique is sadly a thing of the past.
