You'll find all the deets about the incredible weight loss transformations of celebrities like Oprah Winfrey, Adele, Ed Sheeran, and Drew Carey, among others. These testimonies prove that nothing is impossible if you put your heart and mind into it.

Chrissy Metz, This Is Us – 100 Pounds

Chrissy Metz has an inspirational weight-loss story. She has struggled with her appearance since she was little, to the point where she signed up with Weight Watchers at only 11 years old. Metz recently set a goal for herself to get fit after a longtime bout with weight.

She accomplished it, losing 100 pounds by reducing her calorie intake to 2,000 (which is still 800 more than the suggested minimum) and walking 20 minutes every day for nearly half a year. She may still have a long way to go, but we appreciate what the This Is Us star has already achieved.

Rebel Wilson, Pitch Perfect – 66 Pounds

Many can be inspired by a dramatic weight loss of a star like Rebel Wilson, who is internationally famous for playing Fat Amy in the Pitch Perfect films. But then, Wilson dedicated the year 2020 to improve her fitness by resisting sweets and unhealthy food cravings, adopting the Mayr method, and exercising beyond her comfort zone.

She apparently walks 10,000 steps daily and refuses to skip the gym at any cost. Her 66-pound loss proves her dedication, and we're sure she felt proud when Hello magazine recently referred to her shape as an "hourglass figure."

Jessica Simpson, I Wanna Love You Forever - 100 Pounds

Like almost every other female, Jessica Simpson gained a whole lot of weight when she went through pregnancy—all three times. However, what she managed to do faster than most others was recovering her fit figure. The I Wanna Love You Forever songstress, along with the support and encouragement of her personal trainer, Harley Pasternak, lost a remarkable 100 pounds.

As per Women's Health magazine, Simpson walked 14,000 steps regularly, adhered to the Body Reset Diet recommended by her instructor, slept well, and also stayed physically active. With a good career, a beautiful family, and great health, what more could Simpson ask for?

Susan Boyle, Britain's Got Talent - 50 Pounds

Susan Boyle is undoubtedly a contestant you will remember from the third season of Britain's Got Talent in 2009. She gave a notable rendition of I Dreamed a Dream from Les Misérables, which won her a strong reputation in the music business. She went on to launch a total of seven studio albums and thirteen singles.

Boyle was finally ready to focus on her health and embarked on a weight loss journey shedding a significant number of pounds in recent years. Better late than never, right? She lost 50 pounds by cutting out sweets, taking a daily two-mile walk, and using Garcinia Cambogia supplements, as per Style Craze.

Kelly Clarkson, Breakaway - 37 Pounds

Kelly Clarkson is a singer from the United States who catapulted to fame after winning the first season of American Idol. Her success was inevitable, and her $45 million fortune will vouch for it. Being a mother of two made the Breakaway songstress put on some extra weight, but she dropped the extra pounds in no time.

As a result of her perseverance and determination, she shed 37 pounds. Clarkson accomplished this by replacing unhealthy cooking components with healthier alternatives. It's a win-win. These days, she's busy being a daytime host for The Kelly Clarkson Show.

Angela Deem, 90 Day Fiancé - 100 Pounds

Many know Angela Deem as a reality TV personality from her appearance in 90 Day Fiancé. However, her line of work was entirely different before that, having worked in the healthcare industry as a nursing assistant.

Working in that industry would mean that she knows all the pros and cons of going under the knife for weight loss purposes. Yet, Deem opted to get gastric sleeve surgery on top of other work on her breasts, stomach, and so on. Her transformation was undoubtedly notable as she lost a whopping 100 pounds.

Jonah Hill, 21 Jump Street - 36 Pounds

Jonah Hill is a crowd favorite who started in comedic projects like Superbad and This Is The End to serious ones like Maniac and True Story. You might not know this, but Hill was required to lose weight for 22 Jump Street and then put on 40 pounds for War Dogs.

After that, Hill made it his goal to be healthier, and his weight had dropped 40 pounds due to his newfound athleticism. He owes his success to the gym and a dietician. We hope the Oscar-nominated actor's health consciousness inspires youngsters to do the same.

Missy Elliott, Hot Boyz - 30 Pounds

People tend to have different opinions when it comes to health and fitness. American rapper/singer Missy Elliott was never one to obsess over her physique, which explains why fans were surprised when she lost at least 30 pounds.

Apparently, Elliott's perspective suddenly shifted once her doctor informed her that her health was at risk, advising her to size down. Shocked and terrified by the newfound information, the Hot Boyz singer began a healthier lifestyle by consuming fresh and clean food. She also avoided having unhealthy foods such as sodas and other sugary beverages.

Ross Mathews, The Tonight Show With Jay Leno - 50 Pounds

Ross Mathews, also known as Ross the Intern, is an American television personality who earned recognition after interning on The Tonight Show with Jay Leno. Most people had always known Mathews as someone carrying some extra weight (except for that one time in 2007 when he took part in Celebrity Fit Club and lost 40 pounds).

In 2020, however, he embarked on a weight loss journey to release the grief from his mom's passing. Mathews, who is serving as a judge on RuPaul's Drag Race, has already lost 50 pounds, which he accomplished by walking more and cutting down his unhealthy midnight snacking, as per Today.

Busta Rhymes, The Coming - 100 Pounds

If Trevor George Smith Jr., a.k.a Busta Rhymes, can make a lifestyle change and lose weight, who's to say you can't? A 12-time Grammy-nominated rapper and record producer, Rhymes's music career has been a success ever since he released his first album, The Coming.

It's one thing to have to stick around for six kids, but it's equally important to set an example of a healthier lifestyle for them. According to People magazine, Rhymes exercised multiple times a day while consuming more proteins every couple of hours. Doing all those doesn't sound so bad for a loss of 100 pounds, right?

Adrienne Bailon, The Cheetah Girls - 20 Pounds

Adrienne Bailon was born to Latin American parents in New York City. Even though she aspired to become an obstetrician when she was young, her ultimate calling was in music and acting, where she thrived.

Bailon has been the long-running co-host of The Real, but she'll always be remembered for her work as a member of the girl group The Cheetah Girls. She acted on films of the same names as well.

In 2021, O'Donnell made a few appearances as Carrie on The L Word: Generation Q.

Mo'Nique, The Parkers - 80 Pounds

When Mo'Nique pours her heart and soul towards something, it almost always succeeds.

According to Best Health magazine, The Parkers star adopted a raw food diet and kept her body busy by dancing with her trainer Dwight Holt Jr. Mo'Nique's can-do attitude has paid off handsomely for her well-being and appearance, and we're sure her fans are grateful that she shared her journey.

Tiffani Thiessen, White Collar - 45 Pounds

Everything from Tiffani Thiessen's career to her family life is going as smoothly as it can. Some might even say that the mother of two has the perfect life without problems, but that is far from reality. One of the White Collar star's major discomforts was her body weight.

The good thing is, it is no longer haunting her as she got rid of 45 pounds, which were her gains after having children. While there's no one trick to pin-point, she did reveal about her 20-minute power workout to Shape magazine in 2013. As per People magazine, her updated food intake as of 2020 includes a high protein intake.

Oprah Winfrey, The Oprah Winfrey Show - 42 Pounds

Like many other celebrities, Oprah swears by the Weight Watchers program after numerous alternate attempts to lose weight.

As she revealed in O, The Oprah Magazine, work-life balance is as important as everything else in maintaining a healthy body.

Jordin Sparks, Battlefield - 50 Pounds

One of the most challenging aspects of losing weight is sticking to a diet and exercise routine. You overlook the rewards of your efforts within a few days or even weeks, which is why Jordin Sparks, a singer and actress, kept pushing until she lost 50 pounds.

After giving birth to her child, the Battlefield singer shrank her meal portions and stuck to a single dietary pattern. Furthermore, she keeps things fun by participating in physical activities like running, hiking, swimming, boxing, and practicing Sensazao (a type of Zumba) to keep her perspiring. Sparks returned to form quickly postpartum. Cider & Hennessy, her fourth studio album, came out in 2020.

Sherri Shepherd, The View - 40 Pounds

Sooner or later, Sherri Shepherd was likely to make it as an actress in America because of her excellent screen presence and witty demeanor. She rose to prominence after playing Ramona Platt on Less Than Perfect and eventually co-hosting ABC's The View for seven years.

Recently, Shepherd's admirers observed her to be a lot slimmer and leaner. That's probably because she lost 40 pounds.

Brian Baumgartner, The Office – 100 Pounds

The actor who played Kevin Malone's character in the famous NBC sitcom The Office, Brian Baumgartner, was always associated with the heavyweight category. As a husband and a father of two, he may be more concerned about his health than when he was on the show.

We wonder if that's the reason he's gone through a substantial transformation, which, even though unconfirmed, is believed to be a loss of around 100 pounds. Unfortunately, he hasn't revealed much about it to the public. Since The Office, Baumgartner has continued to act, most recently appearing in Trash Truck.

Penn Jillette, Penn & Teller: Fool Us - 100 Pounds

Potatoes aren't a type of food that one would usually associate with weight loss due to them being high in carbohydrates. Somehow, Penn Jillette defied all odds and got rid of 100 pounds by sticking to a potato-only diet. We're guessing it's not so bad when that's all you eat. For anyone who didn't already know, he is one-half of the magician duo Penn & Teller.

Jillette's weight was an insane 322 pounds only a couple of years back, and it followed some bad news regarding his health. His only choice for extending his life was to adopt a healthy lifestyle. As it turned out, everything went smoothly for him. The magician pair is headlining at The Rio in Las Vegas.

Of course, EJ was known as Magic's son, but he earned some fame for himself after appearing in the Rich Kids of Beverly Hills.

Gordon Ramsay, Kitchen Nightmares - 56 Pounds

As a world-renowned chef, Gordon Ramsay sure spends the majority of his time around decadent food. Anyone is bound to put on a few extra pounds when cooking and tasting great food every day for years. Even though it wasn't too noticeable, so did Ramsay.

Well, his wife, Tana Ramsay, wasn't too happy about her husband's extra weight and therefore urged him to be more health-conscious.
