Meghan Trainor looked nearly unrecognizable as she showed off her jaw-dropping weight loss at the Baby2Baby Gala in Los Angeles. The 31-year-old singer dazzled in a princess-style white corset gown from Alin Le Kal at the Pacific Design Center, paired with satin opera gloves and a sequined peplum corset, revealing a slimmer, striking figure that left fans questioning her shocking transformation.

Trainor styled her honey blonde tresses in a chic updo with bangs, while husband Daryl Sabara, 33, joined her on the red carpet. The transformation comes after a dramatic weight loss journey reportedly aided by the use of the drug Mounjaro and breast augmentation surgery (via Daily Mail).
After welcoming her youngest son in 2023, Trainor openly shared her journey toward wellness and self-care.
How Did Meghan Trainor Transform Her Body? Singer Revealed She Took Weight Loss Drugs
Meghan Trainor’s lips are movin’ with her latest reveal. She and her husband, Daryl Sabara, admitted they took the weight loss drug Mounjaro together, an FDA-approved prescription medication for type 2 diabetes that also aids in weight loss. Sabara said on their Working On It podcast:
We did 75 Hard after [our son] Riley was born and, man, did we crush.
Trainor added that they
Heard more and more of our friends — and even our doctors — were on Mounjaro and Ozempic.
She further explained that she had done her research and felt safe, saying, “I did it, too,” while Sabara chimed in, “Daryl and I both do everything together.” The couple stuck to the lowest dose, worked out regularly, and maintained balanced meals. Trainor noted:
We were like, ‘We have to make sure we don’t lose muscle, that we worked so hard gaining all those years.’ And we stay in the gym, we work out, we eat right. And we just noticed that we were less hungry.
“I feel amazing,” Trainor gushed. “Like this thing is incredible. And I have no shame being on it and talking about it.” In March, she took to her Instagram and addressed speculation about weight loss drugs after winning the Hitmaker Award at Billboard’s 2025 Women in Music:
No, I don’t look like I did 10 years ago. I’ve been on a journey to be the healthiest, strongest version of myself for my kids and for me. I’ve worked with a dietician, made huge lifestyle changes, started exercising with a trainer, and yes, I used science and support (shoutout to Mounjaro!) to help me after my 2nd pregnancy. And I’m so glad I did because I feel great.
Speaking to Entertainment Tonight, Trainor credited science for her figure:
Science is the secret. I love it… I was working out so incorrectly wrong for so long. I was running and doing cardio and my body was inflamed, always. I’m trying to bio-hack my body. So anything that’ll help me age backward, I’m into it.
Well, Meghan Trainor’s dramatic transformation sparks both admiration and debate.
Meghan Trainor Revealed Secrets That Made Her Fitter, Healthier, and Happier in 2025
2024 was monumental for Meghan Trainor. To keep up with the demands, she overhauled her workout routine, focusing on strength training instead of cardio. “I just look at all the years that I wasted doing hard cardio… My body was always just angry and inflamed. I was like, ‘What’s wrong with me? Why can’t I do this?’” She told Women’s Health in January 2025.
I know now that my body enjoys lifting weights and it doesn’t make you big and bulky.
The results were immediate: touring helped her shed additional weight, gain strength, and maintain the energy to chase her sons. Trainor and her husband train together three times a week at 9 a.m., while the nanny watches the kids, who sometimes lift pretend kid weights alongside them.
One of her key goals is rebuilding her glutes after weight loss:
I’m trying to grow my butt back, because I lost so much weight that my booty is looking different. I was like, ‘Wait. I’m the ‘Bass’ girl with a big butt!’
Her approach includes heavier lifting and glute-focused workouts, carefully balancing flexibility with sciatic concerns developed during pregnancy. Diet plays a major role: She said she consumes around 100 grams of protein daily, including breakfast staples like eggs and turkey bacon, while relying on meal delivery services for balanced nutrition. “We’re always looking for a new one,” she shared.
Sleep and mental health remain priorities. Trainor ensures she and Daryl Sabara get 7–8 hours of rest and has long worked with mental health professionals, especially through postpartum challenges.
