Celebrities have inspired a lot of people with their weight loss journeys. Check out these before-and-after photos of famous people who've lost dramatic amounts of weight over the years, starting with this iconic vocalist… Back in 2012, fashion designer Karl Lagerfeld rudely called Adele (seen here in 2008) "a little too fat." The following year, he said the Grammy winner was "roundish." Fans were appalled, but the singer claimed she was never affected by fat-shaming. "I've never seen magazine covers or music videos and been like, 'I need to look like that to be a success,'" she told "60 Minutes" in 2012. "I don't want to be some skinny mini with my t*** out. I really don't want to do it and I don't want people confusing what it is that I'm about." But she did make some personal changes for her health after she became a mom. Keep reading to see her transformation in 2015 and how she took things further in 2020 and beyond…

At the same time Adele dropped "Hello" — her first new single in three years — in 2015, she revealed she'd dropped a few pounds as well. Although she never shared how much weight she lost, the Grammy winner did reveal she was hitting the gym to prep for a world tour. In late 2019 and early 2020, new photos of the singer — including some she posted on Instagram herself — revealed she'd lost even more weight: reportedly 100 pounds! Next, see her in October 2020…
Adele delivered laughs (but no new music!) when she hosted NBC's "Saturday Night Live" on Oct. 24, 2020. During her monologue, she showed off her trim figure and quipped, "I know I look really, really different since you last saw me but actually, because of all the COVID restrictions and the travel bans, I had to travel light and only bring half of me — and this is the half I chose." A year later, Adele opened up about what fueled her 100-pound weight loss to Vogue in a November 2021 cover story. According to the mother of one, who was coping with a split from her husband, she discovered that hitting the gym helped with her mental health. "It became my time. I realized that when I was working out, I didn't have any anxiety. It was never about losing weight." The singer added, "I thought, If I can make my body physically strong, and I can feel that and see that, then maybe one day I can make my emotions and my mind physically strong."

Adele showed off her hourglass figure when she performed on the CBS special "Adele One Night Only" on CBS, which aired on Nov. 14, 2021, to promote her new album, "30." "My body's been objectified my entire career," Adele told Vogue in a November 2021 issue cover story. "It's not just now. I understand why it's a shock." She added, "I understand why some women especially were hurt. Visually I represented a lot of women. But I'm still the same person." The "worst part of the whole thing," she explained, "was that the most brutal conversations were being had by other women about my body. I was very f****** disappointed with that. That hurt my feelings." On the 2021 CBS special, Adele opened up even more in an interview with Oprah Winfrey, explaining that working out quelled her "terrifying anxiety attacks" and helped her, with the help of a personal trainer, get to the point where she was dead-lifting 160-170 pounds. She again reflected on the judgement she got surrounding her weight loss. "I was body positive then and I'm body positive now," Adele said. "But it's not my job to validate how people feel about their bodies. And I feel bad that, you know, it's made anyone feel horrible about themselves. But that's not my job. … I'm trying to sort my own life out. I can't add another worry."
Music star Billy Joel — seen here in 2018 — made a major (and unintentional!) lifestyle change in 2021. During an October 2021 appearance on "The Howard Stern Show," the musician said that going under the knife for a back problem led to a 50-pound weight loss. "I had back surgery early this year and the pain afterwards was so bad I lost my appetite. … I embraced that. I said, 'OK, I won't eat as much,' and I ate less and less and less and less and then there was just life aggravation and that tends to, you know, impact your appetite too," he shared. See the results of his slimdown next…
Billy Joel showed off his slimmed-down physique while performing at Madison Square Garden in New York City on Nov. 5, 2021. "I had gotten kind of chunky. I was happy to lose the weight," he said during an October 2021 appearance on "The Howard Stern Show."

In August 2020, fans noticed that Kelly Osbourne (seen here in October 2020) was looking slimmer than ever in some of her Instagram photos, which led Kelly to confirm that she'd indeed lost a significant amount of weight — 85 pounds, she said. Days later on an episode of the "Hollywood Raw" podcast, the TV host revealed she'd undergone gastric sleeve surgery to help her achieve her weight-loss goal. "All it does is change the shape of your stomach. I got that almost two years ago," she said, adding, "I will never, ever, ever lie about it ever. It is the best thing I have ever done." She explained that she "had to do a year of stand-alone therapy to prepare myself for the surgery before I even had it. What people don't realize is it cuts out this hormone that if you have addiction issues, it stops your craving, and it makes you not emotionally eat, and that was a huge problem for me." She said getting sober beforehand helped and warned, "All [the surgery] is is a push in the right direction. It doesn't solve all your problems… It's not a quick fix."
In March 2021, "Perfect Strangers" alum Bronson Pinchot revealed he'd lost an incredible 60 pounds, sharing the before-and-after photos on Instagram. The first pic (seen here) was taken in 2017 when he was filming "Battle of the Network Stars." He told Page Six that he started his slim-down in May 2020 after he saw the snapshot shortly after coronavirus lockdowns began and thought, "There was an old fat guy." The "Chilling Adventures of Sabrina" actor — who's now vegan — said he went through his pantry and fridge and got rid of all the junk food "and then I just put healthy food in the house and I said, 'OK, puppy, you can have whatever's there.'" It was difficult — he admitted he sometimes couldn't sleep because of hunger pangs — but in six months, he'd dropped the weight by following a "self-designed healthy plant-based eating program," he explained on Instagram.
Bronson Pinchot posted this photo of himself on Instagram on March 8, 2021, revealing the results of his 60-pound weight loss. He told Page Six that after slimming down, he went through a box of clothing and mementos from his time playing Balki Bartokomous on ABC's "Perfect Strangers" from 1986 to 1993 — he hadn't touched it for 25 years — and tried on a few things. "And they fit," he said. "And I thought, 'I'm pretty sure I'm the only 61-year-old within a 10-mile radius that's getting into his clothes from when he was a 26-year-old doing two aerobics classes a day.' And that feels pretty good. That feels pretty good."

"I was eating Chinese food every day, twice a day on house arrest," he said, explaining that his weight shot up to 204 pounds by September 2020. He didn't post any photos of himself on social media for five months, then suddenly returned in late February 2021 to reveal the truth of why he was away — and share that he'd lost 60 pounds and was down to 146. "People who don't want to lose weight make a whole bunch of excuses," he told TMZ before offering controversial and not-recommended diet advice: "Starve yourself," he said, "and work out." He also told TMZ he cheated on his diet every three days to treat himself to Gushers candy.
TV host and reality TV staple Ross Mathews, who came to fame as "Ross the Intern" on "The Tonight Show With Jay Leno," has long struggled with his weight.

"Awesome documentary, an anti-sugar documentary that completely changed my perception," he told Men's Health, adding that he grew up paying no mind to his diet. "So then I watch this documentary last year, and I was, like, 'Oh, man, um, I really don't wanna die' — and I'm already 44 years old."

In April 2019, Ariel Winter, who has always been candid about body image, took to Instagram to discuss the reason behind her recent weight loss. "For years I had been on anti-depressants that caused me to gain weight that I couldn't lose no matter what I did. It was always frustrating for me because I wanted to get fit and feel like the work I was doing was paying off, but it never felt that way," she began. She went on to explain how a change in medication improved her metabolism and made her drop the weight. "While I feel better mentally with the change, it's nice to work out and have your body actually respond. I want to gain a few pounds of muscle and get healthier," she added. The actress also revealed that in addition to working out, she'd also cut back on "eating a ton of cheese, bread and greasy food," which helped her feel "more energized and healthier." She's seen here at an event in Las Vegas the same month.

In recent years, she read "The Plant Paradox," a book she said changed her entire eating regimen — and her figure! "It worked wonderfully for me. It's, like, 37 pounds [lost], like, that's a side effect," she said. "Here's the best part, y'all. It's not even the weight. I mean, I know the industry loves the weight gone, but for me it wasn't really the weight. For me, it was [that] I'm not on my medicine anymore. My blood work came back and I haven't been on my medicine since, like, February ." Next up, see her slimmed-down look…
Kelly Clarkson showed off a slimmer figure when she performed on the "Today" show in June 2018, where she explained that she's still eating the food she loves.

Like, literally, I still have everything the same as I did, even, like, fried chicken, but I use, like, casoid flour, tapioca or almond flour. And I use, like, non-hormone chicken." And in 2019, Kelly seemed to be shedding even more weight. The star debuted an even slimmer frame ahead of hosting the Billboard Music Awards in May 2019 (pictured).

While he's been rocking a slimmer figure for years now, earlier in his career, Jimmy Kimmel was unaware of how his eating habits were impacting his overall health. In 2010, when Dr. Oz appeared on his eponymous talk show, Jimmy was called out for his eating and exercise habits. "For years I had no idea what I weighed. I finally bought a scale in 2010. I think I ordered it because I'd read on a gadget website that it had WiFi. I weighed 208," Jimmy told Men's Journal in 2015. "When you see that number, it makes you look at yourself differently."
Intermittent fasting helped Jimmy Kimmel slim down and maintain a healthy weight — specifically a method known as the 5:2 diet. "On Monday and Thursday, I eat fewer than 500 calories a day, then I eat like a pig for the other five days," he explained to Men's Journal in 2015 around the time this photo was snapped. "You 'surprise' the body, keep it guessing." According to the late night host, "It sounds hard, but you get used to it and learn you can get through it. It's helped me stay at 182 pounds. And it's made me appreciate the food that I do eat."

Ricky, who was 58 at the time of the interview, went on to reveal that he believes his age is making it difficult to keep up with exercising. "Because I'm old and weak, I can't work out enough to burn off the calories I take in at night."

"My niece told me this little secret, I guess it's no secret, it's a biological thing, that at some point when you're eating, you have this involuntary sigh and that's really your brain and your stomach communicating that you've had enough," she said. "The trick is to pay attention to that and push your plate away." The transformation took "a few years," she said, adding, "I feel like a completely different person. I can move, I can walk. I just wish I had done it years ago."

"I'd lose 60 pounds every spring, and then I got too fond of the barley corn and I'd just start missing it too much," he said. "And then it would just screw everything up. I'd gain it all back and then some every year." Keep reading to see what he looks like now.
Fortunately, a knee surgery in 2014 caused by years of unhealthy living and weight gain forced John Goodman to get on the right path.
