Meghan Trainor was motivated to start her weight loss journey after developing gestational diabetes.
Speaking to Kayla Thomas on iHeartRadio’s KIISFM, the singer explained the inspiration behind her new song, “Still Don’t Care.”
“I’m getting a lot of hate online just posting who I am, and everyone’s like ‘Why are you thin now? You were ‘All About That Bass’ girl.’ And I was like 19 when I came out with that and I’ve been in a fitness journey since I got healthy — and it started when I was pregnant and I had gestational diabetes.”
This type of diabetes, per Medline Plus, is diagnosed during pregnancy when the body can’t make enough insulin to handle pregnancy hormones, leading to high blood pressure.
She went on to say that she wanted to be her strongest to be able to tour and lift her children “out of their cribs without pulling [my] back.”
“Now I’m strength training three times a week in the gym and I am so focused on health and now I’m obsessed with my hormones, my gut,” she explained.
“I just want to feel good because this job is hard if you don’t feel good. But I got a lot of hate for being thin so it confused me and rattled me.”
Trainor, 31, welcomed son Riley in 2021 and Barry Bruce in 2023 with husband Daryl Sabara.
After welcoming her second son, Trainor began to look increasingly slimmer and shocked fans with her weight loss in early 2025.
Shortly after, she admitted that she had started a wellness journey that included using Mounjaro to lose weight.
The “Dear Future Husband” singer later underwent a breast augmentation and lift.
Since then, she has been flaunting her fit physique on stage and on red carpets, including Kris Jenner’s 70th birthday bash.
Last week, Trainor was forced to clap back at her critics who “attacked” her over her 60-pound weight loss.
“I’m literally for the first time ever, after having babies, taking care of my health to the highest level and I’ve never felt better and I look incredible,” she told “Entertainment Tonight.”
“I feel great and that’s when people attack me,” she added, noting that her critics are “getting louder” and “meaner.”
“I’m taking care of myself,” she reiterated. “I have to find a way to not be affected by that.”
