Meghan Trainor’s stunning weight loss: The truth behind her transformation |

Meghan Trainor recently made headlines at the 2025 Billboard Women in Music event with her dramatic makeover, which left both fans and critics in shock. The singer clarified the scientific techniques she used to get her new appearance, denying the rumors that Ozempic was the cause of her extraordinary weight loss.
The Secret? Science and Biohacking!
In response to the ongoing rumors, Trainor openly talked about biohacking, a method that focuses on enhancing the body’s capabilities scientifically. It was a major influence on her fitness path. She acknowledged that she had made significant lifestyle adjustments, including changing the way she worked out and implementing modern health techniques.
She stated to Entertainment Tonight, “I was working out so incorrectly for so long; I was like running and doing cardio, and my body was always inflamed; I hated it.” She continued, “I switched things up and started weightlifting and exploring biohacking techniques. Now, I’m all about anything that helps me age backwards!”
NAD (nicotinamide adenine dinucleotide), an enzyme that is essential for energy metabolism and ageing, is one of the main components of her new routine. She joked, “I was like, ‘Make me Hailey Bieber—I’ll take it!'” after learning about NADs.
Fighting back against Ozempic rumors
Many social media users were suspicious and confused about Trainor’s transformation despite her honesty, with some accusing her of using Ozempic, a diabetes drug that is frequently used to aid with weight loss. In reference to her 2014 single that praised body positivity, comments like “Girl, just say Ozempic” and “So it’s no longer all about that bass?” were all over social media.
Trainor immediately responded to the rumors with a strong statement. She shared pictures from the occasion and mentioned that people always focus on her weight instead of her music.
“It’s disheartening that so many questions revolve around my body instead of my decade of hard work in the music industry,” she wrote. “No, I don’t look like I did 10 years ago. I’ve been on a mission to be the healthiest and strongest version of myself, not just for me, but for my kids.”
For embracing a healthier lifestyle
The singer also revealed that she received medical assistance and coordinated closely with a trainer and dietitian. “Yes, I’m quite happy that I used Mounjaro following my second pregnancy. I feel fantastic.”
In embracing a healthier lifestyle and prioritizing her well-being, Meghan Trainor stands as a testament to the power of personal transformation through science and dedication, inspiring others to focus on their own journeys rather than comparisons.
