Meghan Trainor Opens Up About Her Weight Loss

Pop star Meghan Trainor’s career took off in 2014 when her debut body-positive single “All About That Bass” topped the Billboard Hot 100 and sold millions of copies worldwide. Since then, Trainor has been in the public eye for a variety of reasons, from her many other hits to her personal life and appearances.

But 11 years later, Trainor’s body is being inspected under the microscope as she admits she has gone through a “fitness and health journey” that has led to her weight loss. While her music helped foster a movement toward self-acceptance, the same listeners who celebrated her message have recently criticized her appearance. That’s why the singer has come out with her latest single, “Still Don’t Care” to combat the “haters” she’s been receiving this year due to her weight loss.

“I’m getting a lot of hate online for posting who I am. Everyone’s saying, ‘Why are you skinny now? Like, you were the ‘All About That Bass’ girl,” Trainor recently shared in a radio interview with 102.7 Kiss FM. “I was 19 when I came out with that song, and I’ve been on a fitness journey ever since.”

The trainer explains that a diagnosis caused him to change his health goals, which led to his weight loss.

“It started when I was pregnant, I had gestational diabetes,” explains Trainor. “And I was like, ‘Oh, I want to learn about health and fitness, and I want to tour forever, I want to be my strongest.’

Having developed gestational diabetes when she was pregnant, the trainer has since prioritized nutrition and exercise in her lifestyle and says she incorporates strength training into her routine three times a week. She also hints that her eating habits revolve around gut-healthy ingredients, and the health of her hormones is essential to her goals.

“I just want to feel good, because it’s hard to do this work if you don’t feel good,” she said. “But I got a lot of hate for being thin, which left me confused and upset.”

With a diagnosis of gestational diabetes, the trainer was more likely to develop type 2 diabetes. So in the April 2025 episode of her family podcast working on itThe trainer revealed that she takes the GLP-1 drug Monzaro, which helped her lose weight rapidly. But it’s clear that the trainer is also taking measures to promote muscle growth and implement a nutrient-rich diet into her everyday life.

Throughout all this, Trainor is unapologetic about her choices, and says she uses songs like “All About That Bass” and “Still Don’t Care” to “reveal what I think about in the future.” It’s never okay to make inappropriate comments about someone’s weight, and Trainer’s message is a reminder that we should value character over appearance.
