Seth Rogen won over hearts with his charm rather than his slightly doughy appearance as Katherine Heigl’s sweet love interest in Knocked Up, but now his radically different physique deserves a second look. The hirsute funny guy lost some serious bulge for his upcoming starring turn in the film adaptation of The Green Hornet. So how’d he do it? “The lamest answer ever, I exercised and dieted,” Rogen said. “I personally do not care how I look or physically feel.” The superhero spandex will definitely care. Read The Daily Beast's interview with Rogen.

Ozzy spawn Jack Osbourne pulled a Jekyll and Hyde during the summer of 2005—he was known as a chubby teen in the family’s reality show, then suddenly emerged as a toned and dapper young man. Osbourne, then 19, melted away over seventy pounds at kickboxing camp in Thailand, which included a high-fiber liquid diet and “coffee enemas.” How…stimulating.

It’s hard to believe that fashion icon Marc Jacobs ever hid his weight under his thick, neo-grunge designs. “For 20 years, I wouldn’t even look in the mirror,” Jacobs said. “I was appalled by the way I looked. The big glasses, the greasy long hair, the oversized clothes, the math professor sweater—all of that wasn’t composed because I loved the way I looked.” Now, Jacobs has the tightest bod in the fashion biz—aside from his skin-and-bones models. He says he shed the weight by switching to an entirely organic diet and spending two hours a day with a personal trainer. Wrote The New Yorker: “He looks like a cartoon superhero: muscular, bronzed, shining with diamonds.”

Former Arkansas governor and one-time Presidential candidate Mike Huckabee nearly charmed pols and the public alike during last year’s election, but fewer know about the conservative preacher’s dramatic weight loss in 2003. The self-described “foodaholic” once weighed in at 300 pounds and—oh my—once crippled a 100-year-old chair in the state capitol. He ditched the “corn dogs, drumsticks and other staples of the Southern-fried political buffet,” became slim and trim, and, in 2005, published a 12-step self-help memoir titled Quit Digging Your Grave With a Knife and Fork. If only that was enough to get him to the White House.

They say the camera adds a few pounds, which never really worked in Al Roker’s favor. The Today Show anchor shed almost 100 pounds in 2002 after receiving a gastric bypass surgery (which was filmed and later aired on Dateline). “In this country, if you have an alcohol problem or a drug problem, you can get treatment," Roker said. “If you have a weight problem, it's lack of willpower: ‘Just push away from the table, tubby, and you'd lose that weight.' But you can stop drinking, you can stop sticking a needle in your arm. You cannot not eat.”

Josh Peck began his career as a slightly chunky teenager on the Nickelodeon sitcom Drake & Josh. Not satisfied to let all the women fawn over his co-star, the 22-year-old dropped over 50 pounds through karate, yoga, and by eating—what a shock!—salads. He says he did it for the young folk: “I know that children do look up to me, so it is my responsibility to motivate people and be inspiring. It doesn't matter what you look like really though, it is who you are that matters of course.” His slimmed-down frame seems to be working in his favor—just last year he starred in The Wackness as a drug dealer alongside veteran actor Ben Kingsley. Peck even had a nude shower scene with Juno’s Olivia Thirlby. Shield your eyes, kids!

He was always cast in the obnoxious buffoon roles on Saturday Night Live but after Horatio Sanz left the skit show in 2006 the comedian dropped around 100 pounds (including that double chin) and now looks less Chris Farley and more hot professor. Even he doesn’t know the exact amount he lost, saying, “I never weighed myself when I was at my fattest, because I was scared I might die.” Well, that’s just not funny at all.

American Idol judge Randy Jackson lost 100 pounds in 2004, but it wasn’t from the pressure of sitting next to the infamously tight T-shirts of Simon Cowell. Instead, he underwent gastric bypass surgery because he was having issues with diabetes. After the surgery he lost 12 inches and went down five shirt sizes. He said of his weight loss: “It really is a big jump start into it because you realize that diet and exercise do work because you’re eating a fifth of what you used to eat and working out.” The former bassist for Journey also recently penned a book about his transformation titled Body With Soul: Slash Sugar, Cut Cholesterol, and Get a Jump On Your Best Health Ever. Don’t ever stop believin’ in the dream, dawg.

Carson Daly was at the front-and-center of MTV’s Total Request Live during the network’s boy band phase but the slightly rumpled host was always more (or less) appealing in the sheepish boy-next-door way. When he scored his own late-night talk show in Los Angeles, Daly shed 30 pounds as part of his New Year’s resolution (oh, so people actually keep those?). He said at the time, “I'm wearing smaller clothes. I don't weigh myself. I don't starve myself. But I (also) don't eat crappy food at night.” Too busy hosting a crappy show at night?
