By Emily Feimster Hollywood may be the land of perfect looks and plastic surgery but not everyone was made to look like Julia Roberts. Yes, it's a place where thin is in, but thanks to certain celebrities, more people are starting to see that big can be beautiful. Thank goodness, too, because how many times can we keep wishing our bodies looked like Brad Pitt's or Angelina Jolie's? In fact, there are a number of famous folks, who, despite having power and fame, still have to struggle with weight. Some keep it under control by strict dieting, but others have come to accept themselves for who they are.

One "Fat Actress" who's been in the public eye since putting on the pounds is Kirstie Alley. Tabloids were printing pictures of Kirstie feasting on fast food before she realized things had gotten out of control. "[Being fat] makes life uncomfortable. I can't move as fast, I can't jump around as much, I can't dress the way I want to. It's an inconvenience to me more than anything," she said in an interview. After making light of her full figure in her Showtime comedy "Fat Actress," Kirstie went on to become the spokeswoman for Jenny Craig and has lost over 50 pounds. Let's just hope she can keep it off!

When it comes to being on-again, off-again with weight, no one knows the story better than Oprah Winfrey. She's gone from a whopping 220 to running a marathon as a size 10. Thanks to her trainer, Bob Greene, she has managed to keep her weight in check, but she's been looking a bit on the heaver side recently. Ah, the summer vacations! But no matter what she looks like, you can't help but love her.

The same can't always be said for the controversial Michael Moore, who never seemed to care much about his appearance until his more recent success with "Fahrenheit 9/11." It was reported that he enrolled at a $3,800-a-week celebrity fat farm, the Pritikin Longevity Center and Spa, in a bid to lose weight. He reportedly learned to cook healthy meals and underwent "life re-education." We'll see.

He's not the only director cutting down. In late June, the "Lord of the Rings" director, Peter Jackson, was barely recognizable. After he wrapped the 'Rings' trilogy and noticed that catered fare on the set had helped pack on the weight, he lost 60 to 70 pounds. He cut portions and ate carrots and fruit instead of gourmet treats. If only the carrots tasted half as good!

Following in their footsteps is the once-chubby Jack Osbourne. After shedding almost 70 pounds, he became unrecognizable by paparazzi, but that's fine by him. "I've been able to live a normal life for the first time in years," he said. To start his program, Osbourne spent a week in a kickboxing camp in Thailand for a detox program, which included a high-fiber liquid diet and coffee enemas. His new lifestyle includes jogging, rock climbing and bedtime at 11 p.m. Drugs, alcohol, cigarettes and junk food are out. Maybe he should have a talk with his sister, Kelly?

Another celeb avoiding the booze is star of ABC's "Less than Perfect," Sara Rue, who has dropped more than 30 pounds over three seasons by not drinking. This summer, she took the slender look a step further by adding a new 'do. She dyed her hair blond and cut it to shoulder length.

Of course who hasn't seen Anna Nicole's slimmer body since she lost 69 pounds using TrimSpa, baby?

Missy Elliott has been showing off her more toned body as well. After cutting back on calorie intake and stepping up her workout routine, the rapper lost nearly 75 pounds. Though she'll always be a big woman, this gal definitely knows how to work it.

Ditto for Queen Latifah, who slimmed down thanks to a specialized diet and strict training regime.

Others grew tired of the constant weight battles and opted for the controversial gastric bypass surgery, including Randy Jackson, Carnie Wilson, Sharon Osbourne, Roseanne Barr, Al Roker, and Nicole Richie's fianc? DJ AM.

Though dieting seems to be an integral part of many of these people's lives, some have chosen to just love the skin they're in. The 449 lb. Ruben Studdard was sponsored by the TV show "Extra" to lose weight, but they soon found out just how much that Southern boy likes his fried chicken!

Comedian Rosie O'Donnell weighs in at 218, but it doesn't seem to be holding her back. The same goes for Camryn Manheim who has made no apologies for being big. "You can either destroy your spirit or you can accept and love yourself just the way you are," she has said.

Some have even made a career out of being big. Just ask past VH1 Celebrity Fit Club participants, Toccara Jones and Mia Tyler, who make a living as plus sized models. In fact, they resisted losing weight because they didn't want their fans to think they were selling out. Said Mia: "I was always a big kid and I'm okay with that, but I know that it would have been better growing up if I had seen role models who had figures like me, beauty comes in all different packages." That it does.
