So here’s a question that fans have been asking for months: What’s going on with Meghan Trainor’s weight loss? If you’ve seen recent pics of the “All About That Bass” singer flaunting her sculpted figure in a mini skirt, then yep, you’re not alone—the internet noticed.
But this wasn’t some overnight, red carpet-ready magic. Nope. This was grit, sweat, some science, and one very honest mama.
The Real Talk Begins: “I Was at My Heaviest After Giving Birth”
Let’s rewind to 2021. Meghan had just welcomed her first son, Riley, with husband Daryl Sabara. And like many new moms, she was navigating more than sleepless nights—she was carrying the heaviest weight she’d ever been.
“I was at my heaviest, I didn’t recognize myself,” Meghan told People in a 2023 interview. “I didn’t feel like me.”
She’d always been body positive, yes. She built a career celebrating curves, remember? But something shifted. “I wanted energy again. I wanted to run around with my son without getting winded,” she added.
And that’s when the real work began.
Meghan Trainor Weight Loss: The 60-Pound Journey
Let’s say it loud for the people in the back—Meghan Trainor lost 60 pounds.
Not in 30 days. Not in some crash diet spiral. But slowly, steadily, and very intentionally. As she puts it:
“I did it the healthy way, the long way—the one pound a week way.”
No gimmicks. No starvation. Just a full commitment to her health, with a little help from science (more on that soon).
She started lifting weights. She stuck to nutritious, home-cooked meals. She leaned on her husband, actor Daryl Sabara, who joined her in the wellness push.
“We became gym buddies,” Meghan laughed during a chat on her Workin’ On It podcast. “We’d compete over who could lift more. It became our thing.”
Was Medication Involved? Yes—and She’s Not Hiding It
In April 2025, Meghan confirmed what fans were already buzzing about online—yes, she used Mounjaro (tirzepatide), a medication FDA-approved for weight loss in people with Type 2 diabetes.
“I’m not going to lie about it,” she told People. “I tried the healthy way. I worked hard. And when I plateaued, I got medical help. It’s not shameful—it’s smart.”
It’s that blend of honesty and openness that’s making Meghan such a powerful voice in the body journey conversation right now.
She’s not pretending she did it all on kale and cardio. But she’s also not chalking it all up to a shot. It was both. Effort and support.
Behind the Scenes: What Her Routine Actually Looked Like
Curious what Meghan Trainor’s weight loss routine really involved? Let’s break it down:
-
Strength Training 3–4 times a week “Weights changed my body and my mood,” Meghan revealed to Healthline. She says it boosted her energy and gave her a new sense of power. Literally.
-
Nutritious meals—no starvation She wasn’t eating air and lemon water. Think grilled chicken, veggies, and snacks that fuel.
-
Mindful eating habits Meghan admitted on Facebook that her biggest challenge was “eating out of boredom.” Relatable, right?
-
Mounjaro as a tool, not a crutch Used under medical supervision, she credits it for helping her through stubborn weight plateaus—but not as the starting point.
The Emotional Rollercoaster: “I Cried. A Lot.”
Let’s be real—weight loss isn’t just a physical thing. It’s emotional. Vulnerable. Sometimes raw.
During a tearful Instagram Live, Meghan opened up about a heartbreaking comment from someone close:
“He told me, ‘You’d be real hot if you were 10 pounds lighter.’ And I was like—cool, let me go cry all day.”
That moment hit hard. But instead of spiraling, Meghan used it. “That was the moment I decided to show up for me.”
She’s been called brave. She’s been called fake. But above all, she’s been honest—and fans are here for it.
After the Weight Loss: “I Got a Boob Job Too”
And just in case you thought Meghan was done being candid—think again.
In March 2025, she revealed she underwent a breast lift and augmentation.
“I did it for me. After babies and weight loss, your body changes. I wanted to feel confident in a swimsuit again.”
That confidence? It’s radiating.
