Meghan Trainor is celebrating feeling stronger and healthier than ever, but she’s found that her personal health journey has landed her in the center of a public debate. The “All About That Bass” singer has been open about losing 60 pounds after the birth of her second child, a transformation achieved through a strict fitness regimen, significant dietary changes, and the use of the weight-loss medication Mounjaro. Despite her focus on well-being, Trainor has faced a wave of criticism and confusion from fans and online commentators who have questioned why the once body-positive icon has dramatically changed her appearance.
The conversation around her body is one Trainor is tired of having. She feels the intense focus on her physique overshadows her music and hard work. In response to the online “attack,” she channeled her feelings into her new song, “Still Don’t Care,” directly addressing the critics who once said she was “too thick” and now say she’s “way too thin.” For Trainor, this journey isn’t about fitting a new mold; it’s about being strong enough to tour and, most importantly, to lift her young children without hurting her back.
How She Transformed Her Health and Body
Meghan Trainor’s path to weight loss was multifaceted, sparked by a serious health wake-up call. During her pregnancy, she was diagnosed with gestational diabetes, which motivated her to learn more about her health and fitness. She realized that to be the active mom and performer she wanted to be, she needed to get stronger.

Her approach was comprehensive. She began strength training three times a week with a trainer, focusing on building muscle. She also worked with a dietitian and made major lifestyle changes, which included cutting out gluten and dairy after being diagnosed with a leaky gut and irritable bowel syndrome. She has been vocal about how these dietary shifts have “fixed so many things” for her.
A key part of her journey, and the one that has attracted the most attention, was her decision to use the medication Mounjaro after her second pregnancy. Mounjaro, which is in the same class of drugs as Ozempic, is a GLP-1 injection traditionally used to manage type 2 diabetes but is also prescribed for weight loss. Trainor did her research, consulted her doctor, and opted for Mounjaro because she felt it had fewer side effects.
She and her husband, Daryl Sabara, even started the treatment together, doing the journey as a team. Trainor has been unashamedly open about this choice, stating, “I have no shame being on it and talking about it.” Her trainer, Bella Maher, emphasized that the medication was a “support, not the reason for her results,” crediting Trainor’s own dedication for the transformation.
In 2025, Trainor also underwent breast augmentation surgery, which she hailed as “the best choice I ever made.” After breastfeeding two children and losing weight, she explained her breasts felt “empty,” and the procedure was something she did for her own confidence.
Navigating the Public’s Reaction and Staying True to Herself
The response to Meghan Trainor’s 60-pound weight loss has been mixed, creating a complex situation for the singer. She has found it confusing that as she began taking the “highest level” of care of her health, the online criticism grew “louder” and “meaner.” This backlash highlights a difficult paradox many public figures face: they are often praised for promoting body positivity but then scrutinized or shamed when their own bodies change.

Some of the criticism stems from her early-career identity. As the 19-year-old who sang “I’m bringin’ booty back” in her hit “All About That Bass,” she was seen as an anthem for body acceptance. When she recently changed the lyrics during a performance to “I got some new boobs,” it sparked backlash from fans who felt she was being hypocritical. Online, people commented that it felt like a betrayal of the song’s original message, with one social media user noting, “Big is beautiful until you’re rich enough to change it.”

Trainor has directly addressed this tension. She reminded everyone that she was a teenager when she wrote “All About That Bass” and has even admitted, “I didn’t believe that when I wrote it.” She sees her current journey as a natural evolution focused on health, not appearance. Her primary motivations are her family and career longevity: to be strong for her kids and to have the stamina to “tour forever.”
Ultimately, Meghan Trainor’s story is a personal one about health and self-care that became a public talking point. She is using her music and her voice to push back against the noise, insisting that her worth is not defined by her dress size. Her experience underlines a broader cultural conversation about why a woman’s personal health choices are so often treated as public property.
