    Playing the huggable Marshall on How I Met Your Mother didn't exactly challenge Jason Segel physically -- he was meant to be the ultimate teddy bear. He says shaping up after the show wrapped meant giving up midnight pizza runs.

    The pizza sacrifice was clearly worth it. Segel says he's now living healthy and eating that way, too.

    Zach Galifianakis says drinking alcohol with meals added girth, which helped him play chubby dudes like the Hangover movies' Alan, but compromised his health.

    Galifianakis reportedly curbed his food intake and lost some 50 pounds. Spring water looks good on you, sir!

    Working and partying virtually around the clock helped Hilton pack on 70 extra pounds. Eventually he was overcome with desire to "look good naked."

    Perez, whose real name is Mario Armando Lavandeira Jr., works out every day -- and certainly looks sharp these days clothed.

    Funny and laid back, Pratt would be adorable at any size. But he has said that hitting the 300-pound mark left him depressed and took a huge toll on his sex drive. I'm sure his wife, Anna Faris (pictured) didn't like that.

    No one is complaining now that he's sporting a newly toned physique, which he was generous enough to show off in Jurassic Park, Guardians of the Galaxy and Zero Dark Thirty.

    The stint on the weight loss show worked, as did laying off junk food. The former dancer (shown here with fans) is back to his trim self. Will Britney want him back? We doubt it.

    But Williams soon gave up his between-tours diet of crisps and cake and reality TV and got back in the recording studio, on the road, and clearly, in the gym. He cropped his own head off in this Instagram pic but man, his body looks good.

  • Mike Tyson: Heavy

    Weight gain can happen to anyone -- even a heavyweight boxing champion like Mike Tyson, who slowly filled out considerably after his career ended.

    Hitting the gym hard (like only a boxer could do) helped get Tyson back into 'Iron Mike' shape.

    Elliot underwent bariatric surgery and started working out after his son's kindergarten classmate imitated him by stuffing a soccer ball in his shirt, embarrasing Eilliot's son. He lost more than 150 pounds.
