Meghan Trainor doesn't want any more health treble.
That's why the "All About That Bass" singer embarked on a journey that led her to lose 60 pounds.
"It started with when I was pregnant and I had gestational diabetes," Meghan—who shares sons Riley, 4, and Barry, 2, with husband Daryl Sabara—recently told Los Angeles’ 104.3 MYfm. "I was like, ‘Oh, I’ve got to learn about health and fitness if I want to tour forever. I’ve got to be at my strongest if I want to lift up my kids from their crib and not pull out my back.'"
These days, the 31-year-old—who has also detailed her and the Spy Kids alum’s experience with GLP-1 medication—is admittedly "obsessed" with wellness, often monitoring her hormone levels and gut health.
"I just want to feel good," she explained, "because this job is hard to do if you don't feel good."
But Meghan was "rattled" by the criticism over her body transformation. As she put it, "I got a lot of hate for being thinner."
"It's weird—I'm finally so proud of myself and starting to love myself, and I've never gotten more hate," she continued. "I was confused, lost, really sad and heartbroken that I took care of myself but everyone's angry."
The Grammy winner added, "Everyone was like, ‘Why are you thin now? You’re ‘All About the Bass’ girl.' I was 19 when I came out with that song and I’ve been on a fitness journey since."
So, how does Meghan navigate the negativity? In addition to pouring her feelings into her new single "Still Don't Care," she also talks it through with her support system.
"My therapist is like, 'You give these strangers so much power,'" Meghan shared, explaining how she once cried in bed over a negative online comment about an outfit she wore. "I hate it when she says that because I was like, 'Ew! I don't want to give strangers power. I want to have my own power and not care.'"

Meghan Trainor Details Her Bangin' New Look
Because you know Meghan Trainor is all about those bangs she debuted in an August 2025 TikTok. While the musician's goal was to show off her core strength, balancing atop a set of dumbbells as part of the social media stiletto challenge, it's pretty clear that her followers' eyes were looking higher.
As one fan commented of her sleek high pony and new fringe, "OMG I didn't recognize you."
Why Meghan Trainor and Daryl Sabara Started Taking Mounjaro
Though the singer was more than happy with the boom boom that all the boys chase, she and husband Daryl Sabara embarked on a health journey after welcoming first son Riley in February 2021.
Eager to ensure that every inch of them was perfect from the bottom to the top, "We did 75 Hard," she detailed on an April 2025 episode of their Workin’ On It podcast, name-checking the strict 75-day program, "and, man, did we crush."
But after youngest son Barry joined the party in July 2023, continued Trainor, "We heard more and more of our friends—and even our doctors—were on Mounjaro and Ozempic.”
And after doing some thorough research, the couple decided to give it a shot, opting for Mounjaro because they felt it “had less side effects.”
Starting the journey together, they paired the lowest possible dose with balanced meals and plenty of sweat sessions. "We were like, 'We have to make sure we don't lose muscle, that we worked so hard gaining all those years,'" she added. "And we stay in the gym, we work out, we eat right. And we just noticed that we were less hungry."
These days she knows she looks good in her Versace dress. "I feel amazing," Trainor detailed. "Like this thing is incredible. And I have no shame being on it and talking about it."
Meghan Trainor Shares Why She Got a Boob Job
When Trainor revealed her plans to get breast implants after welcoming two kids, the reaction made her do a double take. "I’m just an open book, so I was like, 'I’m getting my boobs done,' and all the comments were so nice," she told E! News in March 2025, weeks after revealing the results. "All the moms were like, ‘absolutely.'"
Because she wasn't lyin', lyin', lyin' when she shared how much she wanted the boost. "I had two babies, I pumped everything out of me and then I lost a bunch of weight, and my boobs were like ‘we’re not boobs,’ you know," she explained. “I was like, ‘I’m going to get some new ones,’ and that was my dream."
How Meghan Trainor Feels About Her New Breasts
As for whether Trainor regrets going under the knife, that would be a nah to the ah to the no, no, no.
"I got my dream boobs and they are gorgeous,” she told E! in March 2025. "I look so good naked.”
Before, she was always looking at her chest sideways.
"I've always struggled with loving my boobs before I got them done," she admitted on Instagram. "These breast implants are the only ones in the world with smooth silk, a surface designed to minimize inflammation so the tissue around the implant stays soft. Honestly, they look and feel amazing."
Meghan Trainor Reveals She Got Too Much Botox
All about that face: "I got too much Botox and I need help," Trainor revealed on a December 2024 episode of her podcast. Though she'd gotten injections of the wrinkle-reducing neurotoxin to her forehead before, this time she'd paired it with some lip filler.
"Someone convinced me with my little lips that if you did a lip flip, you put filler right above your upper lip, that you could have a beautiful flip on your upper lip," the singer explained. "And I could have one for the first time in my whole 30 years of living, it was not true."
Instead, she detailed, "I cannot smile. My face hurts to smile, to even try."
