Celebrity weight-loss transformations seen in drastic before-and-after pictures including Jelly Roll

American rapper and singer Jelly Roll, real name Jason Bradley DeFord, was born in December 1984. The ‘Son of a Sinner’ singer started his journey to weight loss in 2022, weighing 540 lbs. 

Three years later, in April 2025, he had lost almost 200 lbs and was hoping to lose even more. He explained on Jimmy Kimmel Live! that the weight loss was mainly down to a diet of protein, vegetables and lots of walking, motivated by several risky activities the musician wants to try, including skydiving and bull-riding.

Singer Lizzo built a brand on self-acceptance but reportedly felt she had to start her "weight release" journey as conversations around her weight were overshadowing those around her music. She started losing weight in 2023 and has slowly been working towards an unstated goal.

In January 2025, she announced she'd reached her goal, returning to her 2014 weight, and seemed to be happy to leave weight release in the past. She has also been critical of the prevalence of weight loss drugs, writing: "We're in an era where the bigger girls are getting smaller because they're tired of being judged."

The Gladiator actor whose toned physique featured on DVD cases across the world opened up recently about his journey to cutting back the calories by leaving casual drinking behind. 

He said on the Joe Rogan Experience podcast that he dropped 60 lbs in a year by cutting out casual drinks and getting injections to reduce inflammation.

Some celebrities like to keep their weight loss journey to themselves and Kelly Clarkson has been particularly private, though she has mentioned she's taking "something that aids in helping break down the sugar" because her body "doesn’t do it right".

She has explained that, while "everybody thinks it's Ozempic, [...] it's not", her doctor "chased [her] for two years, and I was like, 'No, I'm afraid of it. I already have thyroid problems.'"

Comedian Jonah Hill has been open about his weight and weight loss, losing 40 lbs in 2011. In October 2025, he appeared on the set of Cut Off with a new do to boot. The actor has noted the pressures from "public mockery" doled out by "press and interviewers".

Jonah, who said he hadn't taken his shirt off in a pool until his mid-30s, addressed children who might be going through similar issues with their body image, saying: "It's for the kids who don't take their shirt off at the pool. Have fun. You're wonderful and awesome and perfect. All my love."

It's important to note exercise isn't just a way to lose weight: many people, including celebs, find it a useful way to improve their mental health. Adele was one such case. In 2018, she began working out as a way to manage her anxiety and by 2021 had lost 100 lbs. 

She explained to Vogue that her private weightlifting and circuit training sessions helped to focus her mind. "I realised that when I was working out, I didn't have any anxiety. It was never about losing weight". 

The Oscar-winning Ghost actress discussed Oprah Winfrey’s weight loss medication special on The View, telling the audience that Mounjaro had helped her along the way.

She addressed the emotional nature of weight loss and weight gain, emphasising a sensitive approach. "Maybe the key is to stop judging everybody,” she stated. "My weight has come and gone and up and down, but it's never been an issue for me because I don't listen to what other people say about me".

The Modern Family actor received a diabetes diagnosis when he began filming and said it made him feel ashamed, hiding the evidence of "injectables and pills" from Lindsay Schweitzer at the start of their relationship. 

When his father passed away from leukemia, the actor decided to make some changes. "He passed away from leukemia, but the thing that was most painful for him was his diabetic neuropathy. And I just decided, well, I can't go down that road". Since 2022, he’s been taking Mounjaro and hopes to maintain his new weight going forward.
