Waltzing Away the Pounds! Stars Who Had Major Weight Loss Transformations on ‘DWTS’

Joey Graziadei

The season 33 champ admitted, “I definitely got a little too thin quickly,” while appearing on the “Lightweights Podcast” with Joe Vulpis in November 2024.

“Initially you’re doing steps like the jive. We lost so much weight during that week because we were just kicking and flicking and doing so much,” he recalled, referring to partner Jenna Johnson. “Same thing in the samba. You have to move so much in those dances.”

“I’m losing a lot of weight and my size 32 pants, I need a 30 all of a sudden it feels like, ‘cause I’m having to buckle it up so tight,” The Bachelor alum added.

Alyson Hannigan

“I mean it’s insane,” the How I Met Your Mother alum gushed to Entertainment Tonight over the change in her physique, as she lost 20 pounds competing in season 32.

Alyson credited her pro partner, Sasha Farber ,with her new figure. “I can’t even believe — he keeps saying ‘Body by Sasha,’” she shared. The Russia native added, “Contact me on social media to make you look like this,” about Alyson’s sleek physique.

Mauricio Umansky

Despite getting eliminated in week 6 of season 32, the Real Housewives of Beverly Hills star lost a whopping 20 pounds.

AJ McLean

The Backstreet Boys member got ripped after competing on season 29, revealing he lost “a pound a week” since he started rehearsing for the show. “I am eating, but it’s almost like I’m fasting,” he told Us Weekly of the number of calories he was burning.

Lauren Alaina

The American Idol alum revealed she’d lost plenty of weight after being cast on season 28. “I’ve lost, like, 25 pounds since July,” the country singer told Us in October 2019. “None of my clothes fit.” Her pro partner, Gleb Savchenko, sweetly snarked, “You’re welcome.”

Drew Scott

The Property Brothers star dropped 30 pounds from the start of rehearsals through the first five weeks of 2017’s season 25.

“I’m seeing my abs like I’ve never seen them before,” he gushed to Us Weekly at the time. “I have not been a 32 waist since I was in grade eight. I was still active [before], but I just haven’t done cardio like this since I was a teenager.”

Ricki Lake

The former talk show host’s grueling rehearsals with partner Derek Hough helped her shed weight during season 13 of DWTS.

“I didn’t weigh myself at the beginning. I’m definitely a size 6 now. I’ll probably be a size 4 by the end of it,” she told The Huffington Post in 2017 while competing. “It’s come to the point where it doesn’t matter. I no longer wear Spanx. I don’t have lumps where I used to. I will weigh myself at the end. I really like where my body is going. My waist has never been smaller.”

Kirstie Alley

Between being on a Jenny Craig diet and competing on season 12 of DWTS, the late actress lost so much weight fans thought she underwent a weight loss procedure. “NO surgery, NO flippin lasers, NO barfing, NO starving…Jeez…my products, organic food, dance,” she tweeted after finishing in second place during her run on the show.

Kelly Osbourne

The former Fashion Police cohost’s time on DWTS in season 9 saw her lose 42 pounds and change her views on diet and exercise.

“[Partner Louis van Amstel] made me eat turkey burgers and salads and explained to me that a high-protein, low-carb diet would keep me energized,” she told Shape in 2009. “Then I started losing weight and realized, ‘Oh, it’s true what they say: Diet and exercise really work!'”

Marie Osmond

The legendary entertainer lost so much weight during season 5 of DWTS that she landed a gig with Nutrisystem to help keep the pounds off following her third-place finish.

“I’m down 31 pounds so far,” she told OK! magazine while competing in 2007. “I’ve lost about five inches off my hips and five inches off my waist. I’ve added muscle mass and I am much more toned. It’s incredible. The show should be called ‘Dancing With the Starved’!”

Jennie Garth

The Beverly Hills, 90210 alum completely transformed her body when she made it to the semifinals of season 5 in 2007.

“It’s not as much weight as it is inches for me,” Jennie told Us at the time. “We rehearse a lot … I’ve lost inches and dropped a few dress sizes.”
