When Meghan Trainor appeared at the 2025 Billboard Awards, fans were left wide-eyed. “Is that really her?” they wondered, as they saw the singer and songwriter, known for her hit “All About That Bass,” flaunting an incredible body transformation. The 60-pound weight loss seemed almost impossible, given her joyful, confident presence on stage, but it was very real.
Let’s rewind a little. Meghan, now 31, found herself in what she described as a “dark place” after giving birth to her first child, Riley, in 2021. The baby weight, the pressure, the feeling of not being quite “herself”—it was overwhelming. She admitted to struggling with body image post-pregnancy, a sentiment shared by many new mothers. “I felt like I wasn’t living up to the hype. I wasn’t the happy, energetic person I once was,” she said in an interview.
Yet, there’s something undeniably compelling about how Meghan has turned it around, and how she openly shares the gritty reality of her weight loss journey. The singer who once advocated for body positivity and embracing your shape now blends that spirit with a dedication to a more balanced, healthy lifestyle. The change wasn’t just about losing weight—it was about gaining confidence, strength, and health.
Meghan Trainor Weight Loss Before and After: The 60-Pound Transformation
Before:
It was hard not to notice that Meghan’s weight had fluctuated over the years, with her most significant shift occurring post-pregnancy. During her pregnancy, like many women, she gained weight, and by the time Riley was born, she found herself at her heaviest.
“I’d always been confident, but after having Riley, I was in this new body. It was a hard adjustment,” she confessed. And like many who deal with the “baby weight,” she struggled to find a balance between self-acceptance and self-improvement.
After:
Flash forward to 2025, and Meghan’s transformation is nothing short of extraordinary. She managed to shed 60 pounds and has kept it off, but not without work. It’s important to note that this wasn’t just about dieting or cardio—it was a holistic approach to her well-being. Whether it was a combination of fitness routines, mindful eating, or even medical intervention, Meghan found a way that worked for her. The change in her demeanor and confidence was palpable.
Her Instagram photos, showing her proudly donning body-hugging outfits, have gone viral. In one post, she shared a mirror selfie with a caption that resonated deeply with her fans: “I am stronger now, in ways I never thought possible.” The physical transformation is undeniable, but it’s the emotional growth that makes her journey so relatable.
The Secrets Behind Meghan’s Weight Loss: What Really Worked?
So, what was the magic formula? How did Meghan Trainor manage to drop the pounds while staying true to herself? It’s a blend of consistent effort, personal growth, and yes, some surprising health interventions. Here’s what we know from Meghan herself and what the experts have noticed:
1. Strength Training Over Cardio
In her interviews, Meghan has repeatedly mentioned how she switched up her workout routine. “I used to do hours of cardio, but then I realized—why not lift heavier weights instead?” Meghan shared. The decision to focus on strength training rather than the typical cardio regimen was a game-changer. It helped her not only lose weight but build muscle mass, particularly in her glutes—a part of her body that has always been a signature feature. Strength training has been shown to increase metabolism and fat-burning potential, making it an essential part of her transformation.
2. Clean Eating with Flexibility
While Meghan isn’t the type to subscribe to a strict, restrictive diet, she made significant changes to her eating habits. “I stopped eating everything that came in a box,” she told a reporter in 2025. She focused on fresh, whole foods—fruits, vegetables, lean proteins, and healthy fats—allowing her to feel more energized and less bloated.
However, Meghan doesn’t live in the land of deprivation. “I still eat pizza, I just don’t eat it every day,” she jokes. She believes in balance, and it’s this mindset that has made her weight loss sustainable. The key, as Meghan suggests, is moderation, not restriction.
3. The Mounjaro Revelation
In a controversial but honest moment, Meghan finally admitted to using the weight-loss drug Mounjaro, a GLP-1 medication that helps regulate blood sugar and suppress appetite. “I’m not ashamed to say that it was part of my weight loss journey. I needed help, and I’m glad it worked for me,” Meghan explained in an interview. This revelation sparked conversations on social media, with some fans applauding her transparency, while others questioned the ethical use of weight-loss drugs. Regardless, it’s clear that the combination of medication, lifestyle changes, and her own hard work played a role in her dramatic transformation.
4. Mental Health and Mindfulness
Meghan has also been vocal about how important her mental health is in her transformation. She admitted to being in a “dark place” after giving birth and struggled with post-pregnancy depression. “It wasn’t just about how I looked, it was how I felt inside,” she shared. Taking care of her mind has been just as crucial as taking care of her body. Meghan has incorporated mindfulness practices, therapy, and journaling into her daily routine, which have helped her stay grounded and focused on long-term wellness.
5. Support From Husband Daryl Sabara
Meghan’s husband, actor Daryl Sabara, has been a huge source of support throughout her journey. The couple, who welcomed their second child, Barry, in 2023, has made fitness a family affair. Daryl has joined Meghan in her workouts, and they’ve supported each other in adopting healthier habits. “It’s nice to have someone by your side who understands what you’re going through,” Meghan said in an interview. The support from loved ones can be just as important as the workout routine itself.
