Kelly Osbourne

Ozzy Osbourne’s addictions are the stuff of rock 'n; roll legend, but it’s his progeny, Kelly Osbourne, who is the apotheosis of the addictive personality. After her turn as an angsty teenager on her family’s MTV reality series, the Osbourne offspring developed drug addictions and succumbed to emotional binge eating. The rock royalty was in and out of rehab, but what really saved her was another reality show, Dancing With the Stars. The exercise regimen set her on a path toward healthy living, which ultimately helped her lose 42 pounds. Now a size 2, Osbourne recently appeared on the cover of Shape magazine in a bikini, which brought tears of happiness to her eyes. “It was a bit of an emotional roller coaster because I never thought that would be me or I'd ever look like that,” she explained. The now-25-year-old reality star works with Blue Clay Fitness (which includes five days of cardio and strength training) and sticks to a diet of vegetables and fish. "She curses me at the gym," her personal trainer told People magazine, "and thanks me when she's getting dressed."

Jennifer Hudson

She had just given birth to a baby son, and Jennifer Hudson needed to slim down fast to prepare for her role as Nelson Mandela’s wife in Winnie. The Oscar-winning actress decided to forgo Hollywood crash diets and opted instead for a healthier approach. Hudson was incredibly successful working out with a personal trainer and using the Weight Watchers Momentum plan to manage her food intake. As an added bonus to dropping five dress sizes, she landed a gig as the official spokesperson for Weight Watchers. “I’m in the best shape of my life!" Hudson told People magazine. And the 28-year-old star has some advice for those looking to follow in her newly svelte footstep. Firstly, Hudson puts hot sauce “on anything from eggs in the morning to collard greens and even sweet potato fries,” as she told InStyle. She added, “If you want to stay away from eating a cheeseburger, put on a tight-fitting gown and get all made up!”

John Goodman

Though known for his “husky” physique in Hollywood, this former Roseanne star is now nearly half the man he used to be. Once “pushing 400” pounds (as he told David Letterman in June), Goodman ended his cycle of losing weight and putting it back on, with a little extra each time. The 58-year-old actor has dramatically changed his lifestyle—he quit drinking (which means laying off his adored Barleycorn craft brew) and started an exercise and diet regimen. Sources say Goodman shed somewhere in the neighborhood of 100 pounds and along with the weight, he also ditched his signature image. “For almost all his life, he has also been overweight, and his acting draws on both the genuine status that comes with being big, and the stigma that comes with being fat,” The New York Times once wrote. “While Goodman is far more of a big man than a fat one, he's always seen it the other way around.” But these days, Goodman feels great, as he told Letterman, and the comedian hopes to continue to losing weight. He assured the late-night audience, “I’m not going to look like Paris Hilton or anything.”

Jennifer Love Hewitt

The Ghost Whisperer star was mortified in 2007 after unflattering photos of her in a black bikini showed up online—and on every newsstand—specifically focusing on her less-than-toned backside. She decried the coverage (Hewitt was still only a size 2, after all) but employed trainer Stevie Sant'Angelo to tone up. She lost 18 pounds before her 30th birthday last year by sticking to a 1,250- to 1,500-calorie-per-day diet that was heavy on fruits, veggies, and protein, and light on processed foods. A sample breakfast included two servings of mixed fruit and yogurt and she was allowed to have snacks throughout the day. One rule to maintain energy: No whole grains after 3 p.m.

Nia Vardalos

The My Big Fat Greek Wedding star is anything but fat these days. Vardalos lost 40 pounds through plenty of exercise and the abandonment of her favorite food. "I broke up with cheese," Vardalos said. "Cheese keeps calling me and trying to get me to meet at a cheap motel but I'm really committed to just staying single for awhile." She slimmed down in time for her return to the big screen in My Life in Ruins over the summer.

Marie Osmond

The 49-year-old singer lost 45 pounds on NutriSystem, the portion-controlled meal-delivery system that restricted her to three square meals and 1,200 calories a day. She dropped from a size 12/14 to a size 2/4 from the rigorous routine while competing on Dancing With the Stars and a well-intentioned intervention from her kids. She also exercises a bit of mind control: "I freeze grapes. It's like eating sherbet." Osmond recalls that her daughter purged her closet and said "I'm dressing you now because you are hot, and then I can borrow your clothes."

Gwyneth Paltrow

Notice any difference? The always svelte star has a dirty little secret: the Master Cleanse. The diet's main ingredient is room-temperature lemon water, which Paltrow choked down every morning for a seven-day cleansing period during the holidays. She was also allowed coconut milk and small portions of nuts and berries. Gwyneth's helpful tip? "If your bowel movements get sluggish, you can accelerate things by drinking half a cup of castor oil," she wrote on her lifestyle blog/newsletter GOOP. Beauty hurts.

Julia Louis-Dreyfus

The New Adventures of Old Christine star somehow manages to inhabit a world where chocolate and six-pack abs coexist. "I feel like I deserve a treat when I work hard," she told Self magazine in an issue where her toned body graces the cover. "It's important to give yourself a little of what you really want so you don't feel like you're in food prison." Her one vice? Bacon. She can't even keep it in the house.

Valerie Bertinelli

Valerie Bertinelli lost 40 pounds on the Jenny Craig diet, which centers around three principles: food, body, and mind. After months of dieting, blogging about her progress and "squats, squats, and more squats," the former One Day at a Time actress debuted her new body in a bikini on a March cover of People. "It was simply something that was important to me—a ghost I felt I had to overcome," she wrote of the experience. "Maybe your demons don't come in a two-piece...?" Her autobiography chronicling the experience is called Losing It—And Gaining My Life Back One Pound at a Time.

Rebecca Romijn

If her looks, husband, or twin girls didn't cause enough envy, maybe this will: The former model and Ugly Betty star says she lost 60 pounds in the four months after her pregnancy... without dieting. Instead, she had a rather unique tactic: "Breastfeeding is the very best diet I've been on. It's amazing." She said, "It's like you have to eat 5,000 extra calories a day or you can't produce enough food for them. So, that's been fun as well." The actress said, "I think within the first three weeks, I took off like 35 lbs. without doing anything!" "I haven't been able to work out that much because I have twins. It's impossible to get back into a regular schedule."

Mandy Moore

Ryan Adams' recent bride is anything but a "Candy Girl." She joined fitness guru Harley Pasternak's 5-Factor diet plan in 2007, which involved doing five short bursts of cardio a week, and following a five-week diet made up of five meals a day. "I feel better mentally--even if I don't look any different--when I'm putting forth effort to exercise," she has said. And thankfully, 5-Factor allows for occasional cheat days. "But having said that," she continued, "It's not going to push me away if I want to have a cookie at the end of the day. You have to reward yourself every now and then."

Halle Berry

Only a year after the Oscar-winning actress gave birth to her daughter, Nahia, Halle Berry's body was already back to cover-worthy shape. How'd she do it? "Now I'm having to exercise, eat a little bit differently, take a lot more vitamins," she told Harper's Bazaar, adding that "I always had to diet. I'm diabetic, so it's a lifestyle for me anyway just to stay healthy and not end up in the hospital." Her one vice is an oh-so-tempting bag of snacks: "I like Doritos. I'm usually watching The Biggest Loser eating Doritos." Somehow, it's hard to picture that.

Star Jones

The outspoken former co-host of The View underwent gastric-bypass surgery in 2003 and lost a staggering 160 pounds as a result. Though she avoided the topic for years, Jones finally came clean about her weight loss in 2007. "I was an addict for all practical purposes," she told Oprah. "That I had never stuck to a real diet, that I'd never stuck to a real exercise program, and that when confronted by my doctor and the doctor said if you don't make changes, you will die. I had no choice."
