Who Is Meghan Trainor?

Before we explore her transformation, let's appreciate the woman behind the headlines. Meghan Elizabeth Trainor was born on December 22, 1993, in Nantucket, Massachusetts. She burst onto the music scene in 2014 with her debut single "All About That Bass"—a catchy, upbeat anthem that celebrated body positivity and self-acceptance. The song topped the Billboard Hot 100 and made Trainor a household name. Since then, she's released multiple albums, won a Grammy Award for Best New Artist, and become a pop culture icon. She's married to actor Daryl Sabara (best known for Spy Kids), and together they have two sons: Riley, born in 2021, and Barry, born in 2023. But behind the success was a private battle with body image, health issues, and the physical toll of pregnancy and motherhood. Her recent transformation is the result of finally addressing these challenges head-on.

How Much Weight Did Meghan Trainor Lose?

This is one of the most common questions—and the answer is impressive. Meghan Trainor has lost approximately 60 pounds. At her heaviest, she weighed "over 200 pounds". Today, it's estimated that she weighs around 140 to 145 pounds (approximately 63.5 to 65.8 kilograms). Her transformation has been so dramatic that it made headlines around the world. She first debuted her new look on the red carpet at Billboard's 2025 Women in Music Awards in March 2025, stunning in a sleek black dress that showed off her noticeably slimmer frame. But as Trainor herself would tell you, this transformation isn't just about the number on the scale—it's about feeling healthy, strong, and confident for the first time in her life.

How Did Meghan Trainor Lose So Much Weight?

This is the question everyone wants answered—and the answer is a combination of medication, diet, exercise, and a complete lifestyle overhaul. Here's the breakdown of how she did it.

The Health Scare That Started It All

The catalyst for Meghan's weight loss journey came during her second pregnancy. "It started with when I was pregnant and I had gestational diabetes," she told Los Angeles' 104.3 MYfm. "I was like, 'Oh, I've got to learn about health and fitness if I want to tour forever. I've got to be at my strongest if I want to lift up my kids from their crib and not pull out my back." The gestational diabetes diagnosis was a wake-up call. It forced her to confront the reality that her health wasn't just about her—it was about being there for her children and sustaining a demanding career. "I've been on a fitness journey since I got healthy," she explained.

Mounjaro: The Medication That Helped

In March 2025, Meghan addressed online speculation about her weight loss and revealed on Instagram that she decided to take Mounjaro, a GLP-1 medication. Mounjaro is the brand name for tirzepatide—a prescription medication typically used to treat type 2 diabetes. It's often prescribed off-label for weight loss due to its ability to reduce appetite and slow down digestion. Meghan and her husband Daryl both decided to try Mounjaro because research found that it had fewer side effects than other weight loss drugs like Ozempic and Wegovy. She had "no shame" in using the medication. She shared on Instagram: "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." It's worth noting that both Meghan and Daryl took the medication together. They made sure to keep up with their gym routines and diet plans so they didn't "lose muscle that we worked so hard gaining all those years".

Diet: 100 Grams of Protein and Clean Eating

Meghan's dietary approach has been disciplined but sustainable. She revealed to Women's Health that she has a goal of eating 100 grams of protein a day. To achieve this, she often eats: Two eggs and organic turkey bacon for breakfast Recipes from meal delivery services for lunches and dinners Meghan also went gluten-free and dairy-free for five months with the oversight of a nutritionist. She admitted this "has fixed so many things". She explained that she had a "leaky gut" as well as irritable bowel syndrome (IBS), which made it difficult for her body to process certain foods. She told Entertainment Tonight: "Learning how to eat healthy is a science. If everyone knew how to do it, everyone would do it. It is so hard." Her focus on protein-heavy items helped her recover quicker in the gym. She and Daryl were "always looking" for food-prep companies with high-protein options.

Exercise: Strength Training Three Times a Week

Meghan's approach to exercise has evolved significantly. She used to do "hard cardio" and try to be a runner, which left her body "always just angry and inflamed".

Then she discovered strength training—and everything changed. "I know now that my body enjoys lifting weights and it doesn't make you big and bulky," she told Women's Health. Today, Meghan and her husband Daryl hit the gym three times a week at 9 a.m.. She typically lifts weights during these sessions. The results were immediate: "On tour, I lost even more weight and I got stronger, so I could do the show and it was easier at the end," she says. "I could still wake up at 7am and chase after my kids all day at a park while we were traveling. I definitely saw the benefits." If she doesn't have time for a formal workout, she'll use an Apple Watch to track her steps and get some movement in while cleaning her house.

The "Booty Gains" Goal

One of Meghan's current fitness goals is refreshingly honest: she's trying to grow her butt back. "I'm trying to grow my butt back, because I lost so much weight that my booty is looking different," she says. "I was like, 'Wait. I'm the 'Bass' girl with a big butt!'" To achieve this, she's been trying to "lift heavier and do glute activities".

Breast Augmentation: "The Best Choice I Ever Made"

In addition to her weight loss, Meghan also underwent a breast augmentation and lift at the beginning of 2025. She explained the decision candidly: "I had two babies, I pumped everything out of me and then I lost a bunch of weight, and my boobs were like 'we're not boobs,' you know?" She hailed the procedure as "the best choice I ever made" in an interview with USA TODAY and told E! News: "I got my dream boobs and they are gorgeous."

Why Did Meghan Trainor Lose So Much Weight?

The short answer: For her health, her children, and her career. Meghan's weight loss journey began after being diagnosed with gestational diabetes during her second pregnancy. The diagnosis forced her to take her health seriously. She explained: "I was like, 'I've got to learn about health and fitness. If I want to tour forever, I've got to be at my strongest – [also] if I want to lift my kids from their crib and not pull my back.'" She told People that after giving birth to her first son, Riley, she "was in a really dark place" and wanted to be in a great place for her son. Today, Meghan is "obsessed" with wellness and often monitors her hormone levels and gut health. "I just want to feel good because this job is hard to do if you don't feel good," she explained. She's also been clear that her transformation was about strength and health, not just appearance. "I've never been more comfortable in my body," she told PEOPLE in March 2025. "I've been working with a therapist for a long time, trying to rewire my brain to love myself more. It's always a work in progress."

What Is Meghan Trainor Using for Weight Loss?

Meghan has been very open about using Mounjaro (tirzepatide), a GLP-1 medication, as part of her weight loss journey. She confirmed this in a March 2025 Instagram post after facing speculation about her transformation. She also discussed it on her podcast, Workin' On It, with her husband Daryl Sabara.

Why Mounjaro Over Ozempic?

Meghan and Daryl chose Mounjaro because research found that it had fewer side effects than other weight loss drugs like Ozempic and Wegovy. Both Meghan and her husband took the medication together. She told Us Weekly about how she and her family used the weight loss drug together and even paid for her family to use GLP-1s.

The Importance of Lifestyle Changes

It's crucial to note that Meghan didn't rely solely on the medication. She told her fans: "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." Her trainer has insisted that her progress was fueled mostly by discipline and consistency. Meghan is proof that using a GLP-1 alone isn't enough for results—exercise and diet are essential.

The Public Backlash: "I've Never Felt Better and I Look Incredible"

One of the most heartbreaking aspects of Meghan's journey has been the public backlash. Instead of celebrating her health transformation, many online critics have attacked her for being "too thin" or "unrecognizable". She told Entertainment Tonight: "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. I feel great. And that's when people attack me." She admitted that the criticism "confused me and rattled me". She told Extra that she "cried so much" over the harsh comments. "My page is usually a friendly, happy, mom-loving place, but it took a dark turn," she said. "People started commenting about my body, saying I'm too thin, and that they don't recognize me anymore. And I was like, 'Oh, I've just been focusing so hard on my health and my fitness that I've never felt better.'"

The "Walking Nose" Comment

One particularly cruel comment called her "a walking nose". Meghan shared: "Just like, 'Ew, I don't recognize you, you're just a walking nose.' Just crazy stuff, like mean." She tried to tell herself that it doesn't "affect" her, but admitted that "it did".

Kris Jenner's Advice

Meghan found support in reality TV "momager" Kris Jenner, who helped her navigate the horrific online abuse. Her Response: "Still Don't Care" Meghan channeled her frustration into her music. She released the single "Still Don't Care," the lead single from her upcoming album Toy With Me. The song's lyrics address the criticism head-on: "Said I was too thick, then I got way too thin / And I try to stand out, but I wanna fit in." She explained: "I liked the idea of... 'Let me think about it one more time. Nope, I still don't care.' And I know that when I start singing it, it'll be my therapy, my exposure therapy."

Her Message to Critics

Despite the hate, Meghan remains steadfast: "I'm taking care of myself. I have to find a way to not be affected by that." "I've never felt better and I look incredible. I feel great." "I'm finally so proud of myself and starting to love myself, and I've never gotten more hate."
