2023’s Biggest Weight Loss ​Transformations, From Kelly Clarkson to Trisha Yearwood: Before and After Photos

Kelly Clarkson

Over the years, the talk show host’s weight has fluctuated, but fans were stunned when she debuted her new slim figure just in time for The Kelly Clarkson Show’s move to NYC. The mom of two, 41, reportedly dropped 40 pounds from her 5-foot-2 frame by sticking to Dr. Steven R. Gundry’s Plant Paradox diet.

The eating plan revolves around the concept of eliminating lectins. “I don’t even need to wear Spanx anymore,” the slimmed-down divorcée joked before complaining that her new studio is ice-cold. “I just wear them for warmth, like thermals!”

Charles Barkley

The NBA great, 60, revealed he was using Mounjaro, a drug originally used to treat type 2 diabetes but increasingly used for weight loss, in May.

“I’m working out, I’m taking my shot once a week,” the 6-foot-4 star said on The Dan Patrick Show, announcing that he’d dropped a whopping 62 pounds. “I started at 352,” he said. “And I’m down to 290. I’m starting to feel like a human being, not a fat ass anymore.”

After revealing his goal weight of 270, the dad of one shared his doctor’s sobering words: “She says, ‘There’s a lot of fat young people. Ain’t a lot of fat old people. They’re all dead.’”

Kelly Osbourne

The reality vet is no stranger to extreme weight loss, having dropped 85 pounds after undergoing gastric sleeve surgery in 2018. But since welcoming her first child with Slipknot’s Sid Wilson in 2022, the 39-year-old admits she overdid her postpartum slimdown.

“I was like, ‘Well, I lost all the baby weight. Let’s see how far I can go with it,’” the 5-foot-2 star shared. “And then I went a little too far.”

Kelly has been honest about her body-image struggles, admitting she hid her pregnancy to avoid negative comments about her figure — something she now regrets: “It made me sad because I didn’t get to show off my pregnancy belly.”

Trisha Yearwood

Back in 2013, the country singer revamped her eating habits to a low-fat, low-sugar diet “90 percent of the time.” The result: 30 pounds lighter on the scale. But over the years, the 5-foot-8 Trisha’s Southern Kitchen star felt the weight coming back.

“She’s a total foodie, she loves to cook and eat,” an insider exclusively tells Life & Style. “She decided to get back on the program by portioning out her meals and being mindful.”

At 59, Trisha also has to work harder at the gym to build muscle. In a December 18 Instagram post, the “Walkaway Joe” singer debuted the 10-pound trimdown — and her new bangs. Said one commenter: “You look great!”

Scott Disick

Sidelined by a back injury after he flipped his Lamborghini SUV in August 2022, the 40-year-old saw his waistline widen. “He couldn’t exercise because he was in excruciating pain,” an insider exclusively tells Life & Style.

“Scott was eating a lot of junk food and the weight piled on. He hated the way he looked and felt.” But physical therapy (and, some whisper, using a weight-loss drug) helped the dad of three regain control, and on a December 20 outing in Beverly Hills, the 5-foot-11 Kardashians star revealed he’s shed dozens of pounds.

“He lost all the weight and then some,” says the insider. “He feels better than he has in a long time.”
