Meghan Trainor Reveals the Truth Behind Her 60-Pound Weight Loss: A Journey of Science and Self-Discovery

Meghan Trainor has always been open about her weight loss journey, but her latest transformation has sparked intense speculation and curiosity. Recently, the “All About That Bass” singer revealed the surprising truth behind her physical changes, attributing her success to a combination of science and a series of new lifestyle changes she’s embraced.

“I’m Trying to Biohack My Body,” Meghan Shares Her Health Secrets

At the 2025 Billboard Women in Music event, Meghan Trainor took a moment to speak with Entertainment Tonight, revealing what has truly been behind her impressive weight loss. In an exclusive interview, she shared, “Science is the secret. I love it.” For Trainor, it’s not just about conventional methods like working out—it’s about diving deeper into the science of health and fitness.

Meghan admitted that, for a long time, she had been doing her workouts all wrong. “I was running and doing cardio and my body was inflamed, always,” she confessed. Instead of chasing traditional weight loss methods, she took a more scientific approach to her body and health. And that’s when things started to change. “I’m trying to biohack my body,” Trainor added. Her commitment to better understanding her body has led her down a path of self-discovery that has transformed her life.

NAD Supplements: The Secret Weapon Behind Meghan’s Transformation

One of the key things Meghan has discovered is the power of NAD supplements. She excitedly explained that she’s been learning about these anti-aging supplements and experimenting with them as part of her routine. “I just learned about the NADs. I was like, ‘Make me Hailey Bieber. I’ll do it. I’ll take it,'” she laughed, sharing her enthusiasm for her new approach.

So, what exactly are NADs? Nicotinamide adenine dinucleotide (NAD) is a naturally occurring compound that plays a vital role in energy production within the body. As we age, NAD levels naturally decline, which can affect everything from our energy levels to our ability to repair DNA. Experts explain that NAD+ is central to cell function, immune health, and metabolism. Emma Wedgwood, an advanced nurse practitioner, explained to GQ that NAD is essential for converting food into energy, and its decline as we get older is one reason why some of us struggle to maintain energy levels. For Meghan, it’s all about tapping into this science to help her feel youthful and energized again.

Why Meghan Trainor is All About “Aging Backward”

Meghan Trainor’s approach to health and wellness isn’t just about weight loss; it’s about longevity and aging gracefully. She described her journey as being focused on “aging backward”—a concept that resonates deeply with many people today, especially as wellness and anti-aging trends continue to dominate. By using supplements like NAD and focusing on understanding her body’s deeper needs, Meghan is on a mission to turn back the clock and reclaim her vitality.

From Over 200 Pounds to Feeling Better Than Ever

Meghan’s transformation didn’t happen overnight. The singer, who has always been candid about her weight struggles, previously shared that she was over 200 pounds after giving birth to her first son. “I was my heaviest I’ve ever been,” Meghan recalled during an interview with ET Canada in 2022. “I wasn’t feeling great.”

But instead of rushing into extreme measures, Meghan chose a more patient path to weight loss. She challenged herself to lose the weight gradually, saying, “I was like, ‘If I can survive a C-section, I can do anything!’” She slowly made changes, focusing on healthier eating habits and incorporating exercise into her routine. “I started seeing the pounds come off like one week at a time, one pound…” she shared. This patient approach paid off, and eventually, she lost 60 pounds after giving birth, revealing her dedication to finding a sustainable approach to health.

Learning to Love Healthy Food and Exercise

Through this journey, Meghan learned that she genuinely enjoys healthy food and the benefits of regular exercise. “I learned what portions mean. And I learned my brain is so happy when I exercise, so I’m just feeling better than ever.” These insights have been a crucial part of her transformation. It’s not just about losing weight—it’s about developing a lifelong relationship with food and fitness that brings her joy and energy.

Meghan’s story is an important reminder that weight loss is not always about drastic changes or chasing the latest trends. It’s about finding what works best for you, in your own time, and with an understanding of your body’s needs. And for Meghan, it’s all about blending science, self-love, and a little bit of biohacking to achieve her goals.
