Meghan Trainor’s ‘Too Thin’ Backlash Proves We Missed the Point

The Moment

Meghan Trainor is once again explaining why her body is nobody’s group project.

In a recent chat with radio host Kayla Thomas on iHeartRadio’s KIIS FM, the 31-year-old singer said a health scare during pregnancy – gestational diabetes – is what pushed her into a serious health and fitness journey. That journey eventually included strength training, hormone and gut-health work, and the prescription medication Mounjaro as part of her weight-loss plan.

She says the backlash has been brutal. Online commenters are apparently demanding to know why the woman who sang the body-positive smash “All About That Bass” is now visibly slimmer. As Meghan put it, people keep asking, “Why are you thin now? You were ‘All About That Bass’ girl.”

Her answer: she got scared when she developed gestational diabetes while pregnant, and she wanted to be strong enough to tour, work, and literally pick up her kids without throwing out her back. According to a recent entertainment report, she’s lost a significant amount of weight, used Mounjaro under medical care, and later had a breast augmentation and lift.

Now she’s turning the noise into music. Her new track, “Still Don’t Care,” calls out the exact whiplash she’s been living: once “too thick,” now “too thin,” never just right for the internet jury.

The Take

I’m just going to say the quiet part out loud: a lot of people never wanted Meghan Trainor, the person, to evolve. They wanted Meghan Trainor, the brand – the curvy, cutesy “All About That Bass” cartoon character who would stay the same size forever so we could all feel better about ours.

Once she changed her body for her own reasons, some fans treated it like a betrayal, not a medical and personal decision. That isn’t body positivity. That’s body possession.

What Meghan is describing is the classic female-celebrity trap: you are marketed as an idea, then punished when you grow out of it. If she had stayed bigger, there would have always been trolls calling her unhealthy. Now that she’s smaller, the same energy is back, just wearing a different outfit.

It’s like hiring an actress to play a role in your favorite TV show and then getting mad 10 years later that she changed her hair, had kids, and doesn’t wear the same jeans. Fans got attached to a moment in time and forgot she was a human being in a body with hormones, pregnancies, and lab results.

Let’s also clock the generational piece. Meghan was only about 19 when “All About That Bass” dropped. A teen wrote a catchy pop song about feeling good in her skin – she did not sign a lifetime contract to be the inspirational poster child for every stranger’s body image journey.

There are fair conversations to have around celebrity weight-loss drugs. Mounjaro and its cousins are serious medications, not gummy vitamins, and they are rightly controversial when it comes to supply, long-term health, and diet culture. But that is a system conversation – about doctors, drug companies, and Hollywood pressure – not an excuse to dogpile one working mom who got scared when her blood sugar spiked.

And the lyrics to “Still Don’t Care” hit harder when you see the context. She sings about being told she was too thick, then way too thin, and trying to stand out but wanting to fit in. That’s not a clapback from a smug diet ad. That’s someone realizing there is no safe size if you let the internet hold the measuring tape.

Here’s my take: if body positivity only works when a woman’s measurements stay exactly where you liked them, it was never positivity. It was control dressed up as empowerment.

Receipts

Confirmed

• In her KIIS FM interview with Kayla Thomas (shared on YouTube in November 2025), Meghan Trainor said she developed gestational diabetes during pregnancy and that it kicked off her serious focus on fitness and health.
• In that same interview, she described getting “a lot of hate” for being thin, and quoted people asking why she isn’t the “All About That Bass” girl anymore.
• She said she now strength trains three times a week and is focused on her hormones and gut health so she can feel good enough to do her job and care for her kids.
• According to a November 21, 2025 celebrity report summarizing her comments and recent public appearances, Trainor has talked about using the prescription drug Mounjaro as part of her wellness and weight-loss journey, and later having a breast augmentation and lift.
• Her new single “Still Don’t Care” includes lyrics about being called too thick and then too thin, and about people saying she’s “hard to like,” matching the themes she’s brought up in interviews.
• MedlinePlus, a U.S. National Library of Medicine resource, describes gestational diabetes as a type of diabetes that develops during pregnancy when the body cannot make enough insulin to manage pregnancy hormones, leading to high blood sugar.

Unverified / Needs Context

• Some coverage mentions a specific number of pounds lost; that exact figure does not clearly appear as a direct quote from Meghan in the material available.
• Descriptions of fans being “shocked” by her new look are interpretations based on social media reactions, not measurable facts.
• One write-up appears to list her sons’ birth years as 2001 and 2003, which would be impossible given her age; widely reported timelines place their births in the early 2020s.

Backstory (For Casual Readers)

If you lost track of her after the radio era, Meghan Trainor burst onto the scene in 2014 with “All About That Bass,” a retro-pop earworm that became a sort of unofficial body-acceptance anthem. She went on to win a Grammy for Best New Artist, marry actor Daryl Sabara (best known from the “Spy Kids” movies), and have two children. Over the years she’s spoken openly about anxiety, childbirth, and her changing body, which is part of why fans feel so connected – and also why they sometimes forget where the boundaries should be.

What’s Next

In the short term, expect more of Meghan doing what she does best: talking and singing about the stuff most pop stars try to hide. “Still Don’t Care” is clearly designed as both a comeback single and a line in the sand about what she will and won’t explain.

It wouldn’t be surprising if she addresses the Mounjaro conversation more directly in future interviews, especially as Hollywood’s injectable-weight-loss era keeps dominating talk shows and red carpets. There is a real need for honest, medically grounded information – and also for a reminder that no one online is your doctor.

For fans, the next step might be quieter: deciding whether we actually mean it when we say women’s bodies are their own. If Meghan Trainor can move from “All About That Bass” to “Still Don’t Care” and survive the comments section, maybe that’s growth for all of us.

One question for you: when an artist becomes famous on a body-positive message, do you feel let down when they dramatically change their body later, or do you see it as them living the very autonomy they preached?
