Meghan Trainor Has Been Open and Honest About Her Weight Loss Journey! See Her Transformation Photos

‘All About That Bass’

Meghan stepped onto the scene in 2014 with her debut single. She’s since explained how the song was for herself with a focus on her “body insecurities.”

“I was already at a tough place with my body, especially being out in front of all those people and having them judge me,” she told People in September 2021. “A lot of people in the beginning of my career would say stuff to me in person like, ‘Well, you’re much skinnier than I thought you’d be,’ or just weird backhanded comments,” Trainor says. “So I’ve had a very weird relationship with my body for a lot of years, especially because I grew up chubby.”

Embracing Fame

Following the success of “All About That Bass,” Meghan started to understand how her fans felt.

“After the video for ‘All About That Bass’ came out … when I was signing autographs, this girl came up to me bawling and said, ‘You make me feel pretty again. Thank you,’” she recalled to  Seventeen in February 2015. “It really resonated with me that this girl was so gorgeous and she didn’t even know it.”

Unreleased Music

While chatting with USA Today in May 2016, Meghan revealed that she has written an unreleased song titled “Curves.”

Making a Change

In 2016, fans will recall that Meghan went for a darker hair-do.

Her Icon Status

Meghan has walked various red carpets over the years with some pretty memorable outfits!

Dressing for Her Body

When it came to dressing for her body, Meghan said she “wore baggy clothes and leggings” to hide herself.

“I felt insecure and I didn’t know how to dress my body,” the singer told The Guardian in March 2020. “I’m still learning what looks awesome on me – it’s a dangerous game of expensive clothes.”

Becoming a Mom

After welcoming her son, Riley, the musician changed her life.

“I was my heaviest I’ve ever been, I was like over 200 pounds when I C-sectioned him out,” Meghan told ET Canada. “I just wasn’t feeling great. I’ve never had stitches, so to have this C-section scar, I was in a really dark place and I wanted to be in a great place for my son.”

2022

The “Made You Look” singer showed off her trim waist in a pink sequin two-piece pantsuit at the American Music Awards in Los Angeles in November 2022.

“I learned that I do like healthy food and I learned what portions mean,” Meghan explained. “And I learned my brain is so happy when I exercise, so I’m just [feeling] better than ever.”

2022

Meghan looked like a winter wonderland queen on the set of the e.l.f. Cosmetics Holiday Glow Storm shoot in Los Angeles in November 2022.

Baby No. 2

In January 2023, Meghan announced that she was pregnant with her second child. She gave birth to a second baby boy that July.

Back to Work

By November 2023, Meghan was back in the spotlight following the birth of baby No. 2. She attended an event at the Grammy museum and put her post-baby body on display.

Red Carpet Ready

Meghan attended the iHeartRadio Music Awards in April 2024. 

“Body image is always there, but I’m learning to rewire my brain,” she admitted in a previous interview. “And I saw this girl on TikTok sobbing in her car and said, ‘I’m 30 years old and I finally love myself fully, all of me, my body, who I am.’ Sobbing. And she was like, ‘I want you to know you could love yourself someday too. It’ll happen.’ And I was like, ‘I love TikTok.’”

Women In Music

Megan reflected on her weight loss journey after she was honored by Billboard Women in Music as a Hitmaker in March 2025. “What a dream!” she wrote on her Instagram alongside photos from the event. “But it’s a little disheartening that so many of the questions (and comments) were focused on my body instead of my music, my passion, or the decade of hard work that got me here. This is what it’s like to be a woman in the music industry.”

The mom of two continued, “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.”

Megan concluded, “Here’s to celebrating talent, growth, and the power of putting yourself first. Let’s keep shifting the convo to what REALLY matters.”

Hello Hottie!
