Country superstar, Jelly Roll, started his weight-loss journey in late 2022 and announced he lost 100 pounds in October 2024.
In December 2025, the “Save Me” singer opened up about his continued weight-loss on “The Joe Rogan Experience,” sharing that he lost 300 pounds. While on the podcast, he shared he “spent most of 2022 between 480 and 560 pounds.”
He explained that he had been trying to lose weight his entire life but started taking it seriously when he turned 39, saying, “I knew my next one was 40 … I don’t think I’ve ever met a 500-pound 40-year-old.”
“I was like, ‘Man, I should really start trying to figure this out’ … I could feel myself dying, Joe,” he said.
Jelly Roll previously opened up about his struggle with “food addiction” in a November 2024 interview with People. He explained his relationship with food had never been “healthy,” but “once you get into that discipline and commitment, it’s like an avalanche,” he said, adding “once that little snowball started rolling, it was on its way.”

Meghan Trainor shocked fans when she walked the red carpet at the Billboard Women in Music event in March 2025 in a skintight strapless black dress which showed off her slimmed-down figure.
Initially, the “Made You Look” singer attributed her weight loss to biohacking, telling Entertainment Tonight at the event that “Science is the secret. I love it,” adding that she learned the best methods to stay healthy for her body.
Just days later, however, the Grammy Award-winning singer admitted on Instagram that she used Mounjaro to help her lose weight, while also encouraging fans to celebrate “talent, growth, and the power of putting yourself first.”
“No, I don’t look like I did 10 years ago. I’ve been on a journey to be the healthiest, strongest version of myself for my kids and for me,” the mom of two added. “I’ve worked with a dietician, made huge lifestyle changes, started exercising with a trainer, and yes, I used science and support (shoutout to Mounjaro!) to help me after my 2nd pregnancy. And I’m so glad I did because I feel great.”

Quinton Aaron, best known for his role in the 2009 movie, “The Blind Side,” shared in October 2025 that he lost over 200 pounds following a near-death experience.
“There’s one day I’m sitting there on the wall, and I’m just listening to the water vibe, and then I wake up underwater,” he told Fox News Digital. “So I literally passed out, fell off the wall, and it was like a 12-foot drop, but the water was only three feet deep. I didn’t know that at the time. Well, thank God it was three feet deep, because I can’t swim.”
He described feeling excruciating pain as he tried to stand up, later learning his fall may have been caused by diabetic ketoacidosis, a complication from extremely high blood sugar levels.

Aaron described learning about his condition as a “come-to-Jesus kind of moment,” after which he began intermittent fasting, stopped overeating and “cut out sugars, and so with just those three things, the weight just started dropping off tremendously.”
“It wasn’t an overnight process,” Aaron said. “It definitely took some work, but my mindset was at that point where it was like, I got a lot of things I want to live for. At the time, I was single. I’ve always wanted to be married and have kids. And I’m like, ‘What condition am I gonna be in if I had kids? I gotta make these changes.’”

“Mike & Molly” star, Billy Gardell opened up about his dramatic 170-pound weight-loss journey during a December 2025 interview with People.
“I was medicating my emotions and my fears with food, and I was also celebrating my victories with food,” Gardell, told the outlet. “You’re eating to deflect your feelings when they’re bad or enhance them when they’re good, and both of those things are poison pills.”
He added that he “had gotten so big and so stationary that it hurt to stand up.”
Gardell shared that in 2020 he weighed 370 pounds and in 2021 felt he had no choice but to undergo bariatric surgery out of “desperation.” He now says he fluctuated between 210 and 215 pounds.

“You have to learn to love yourself,” he said. “You have to look at why you react the way you do to food and heal that, and then love yourself enough to do something good for yourself.”
