Meghan Trainor recently left fans divided after she changed a lyric in one of her most popular songs following her medicated weight loss.

The 31-year-old singer has been candid about losing weight via medical intervention, using the drug Mounjaro - which has traditionally been used to treat Type 2 diabetes - as a weight management tool. The drug has also been recently tested for efficiency in weight loss compared to its competitor Wegovy, and the results crowned one clear winner.

Sharing details of her weight loss journey on Instagram, Meghan revealed that she wanted to become a healthier version of herself for her children's sake. Posting a selfie last month, Trainor opened up about using Mounjaro.

She wrote: "Feeling so honoured to be recognised by @billboard Women in Music as a Hitmaker - what a dream!

"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."

Meghan, who's mum to Riley, four, and Barry, 21 months, added: "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. Here’s to celebrating talent, growth, and the power of putting yourself first. Let’s keep shifting the convo to what REALLY matters. With love."

Well, her new look is likely the reason she changed one of the lyrics while performing her 2014 body positivity anthem 'All About That Bass' most recently, and it's left fans divided.

During her performance at iHeartRadio’s Wango Tango, she changed a notable line from 'It’s pretty clear, I ain’t no size two' to 'It’s pretty clear, I got some new boobs'.

And it's left people torn.

One person wrote online: "I can only imagine how hard it would be for people who connected with her early in her career because she was body positive to see her succumb to Ozempic."

And another wrote: "As someone who was not a size 2 when I first heard this song when I was like 13, for her to change the lyrics just feels hypocritical to me? Like I’m glad she feels good in her body and you know taking ozempic helped her do that but like…man idk."

It's important to note that while Ozempic and Mounjaro have both been used by celebs for weight loss, only one of them is actually prescribed for weight loss.

Alongside Ozempic, a type 2 diabetes drug, Mounjaro is often used to aid weight loss.

Mounjaro contains tirzepatide, which is a little different from Ozempic as it's a medication which has been recently approved for weight loss management as well as diabetes as it helps lower blood sugar levels. So, unlike Ozempic, this one is actually approved to aid weight loss.

A key difference between Mounjaro and Ozempic is that Mounjaro targets both the GLP-1 and GIP receptors, instead of just the GLP-1 receptor, which are two appetite-regulating hormones.

So, it’s basically a dual action drug which also improves blood sugar control and supports weight loss.

Amy Schumer, Gemma Collins, and Jeremy Clarkson have all opened up about using Mounjaro.
