Meghan Trainor has always been the face of "loving yourself exactly as you are." When she hit the scene with All About That Bass, she basically became the patron saint of body positivity for a whole generation. So, when the Meghan Trainor weight loss before and after photos started circulating recently, it sparked a massive, messy conversation. People were confused. Some felt betrayed, like she’d abandoned the "bass" for the "treble."
But if you actually listen to her, the story isn't about fitting into a sample size or caves to Hollywood pressure. It was about survival. Honestly, she was in a dark place after her first C-section in 2021. She’s been super open about hitting 200 pounds and just... not feeling like herself. Her brain was foggy, her body felt "angry and inflamed," and she was struggling with the physical toll of motherhood.
The 60-Pound Shift: It Wasn't Overnight
Everyone wants a magic pill, but for Meghan, it started with a literal medical wake-up call. During her pregnancy, she was diagnosed with gestational diabetes. That changed everything. Suddenly, she wasn't just eating for cravings; she had to track her blood sugar four times a day. It was like a crash course in how food actually affects the human body.

"I had to learn about health and fitness," she told ET Canada. She wasn't trying to be "skinny." She wanted to be able to lift her kids out of their cribs without her back giving out. That's a "why" that actually sticks.
The Truth About the Medication
Let’s address the elephant in the room. In 2025, Meghan got incredibly real about using Mounjaro (a GLP-1 medication similar to Ozempic). She didn't hide it behind "drinking more water" or "just walking." She admitted she used it as a tool after her second child, Barry, was born.
However, her trainer and Meghan herself have been adamant: the meds weren't a "get out of jail free" card. She used them to help manage her hunger and metabolic health while she did the actual, grueling work in the gym. It was a "support," not the whole story.
Trading the Treadmill for the Squat Rack
For years, Meghan did what most of us do: endless cardio. She ran and ran, and she ended up feeling "swollen."
Everything changed when she started lifting.
She began working out with her husband, Daryl Sabara (yes, the Spy Kids guy), three times a week. They focused on strength training. We're talking squats, deadlifts, and heavy weights.
Why? Because muscle is metabolic gold.
By building lean muscle, she increased her basal metabolic rate. This meant she was burning more calories just sitting on her couch than she used to. Plus, her "brain is so happy when I exercise." She actually credits the lifting for pulling her out of her postpartum slump.
What Her Daily Meals Actually Look Like
She’s a creature of habit. Kinda relatable, right? She doesn't do "chef-prepared" 12-course salads.
- Breakfast: Almost always two eggs and organic turkey bacon. Simple.
- Lunch/Dinner: Usually "power bowls" or meal delivery kits that focus on a mix of lean protein and complex carbs like quinoa.
- The Protein Goal: Her trainer pushed her to hit 100 grams of protein a day.
Getting that much protein is a full-time job. She’s mentioned that she and her managers literally text each other when they hit their protein goals for the day. It’s a total mindset shift from "eating less" to "fueling more."
Dealing With the "Backlash"
It’s weird, right? You get healthy, you feel great, and then the internet attacks you for not being the "old" you.
Meghan has faced a ton of heat from people saying she’s "too thin" or that she’s no longer the body-positive icon she used to be. Her response? It’s basically: I’m 31 now, not 19. My body has been through two C-sections and two kids. I’m allowed to evolve.
She’s even using her music to process it. Her song "Still Don't Care" is basically a middle finger to the people who think they own her silhouette. She’s pointed out that she’s taking care of her health at the highest level for the first time in her life. If people have a problem with her being strong enough to tour and play with her kids, that’s on them.
Actionable Insights from Meghan’s Journey
You don't need a pop star's budget to take some of these lessons to heart.
- Prioritize Protein: Stop focusing on what to "cut out" and focus on hitting a protein goal (aim for 25-30g per meal). It keeps you full and protects your muscle.
- Lift the Heavy Things: If cardio makes you feel "inflamed" or exhausted, try switching to resistance training three days a week. It changes your body composition in a way walking never will.
- Find Your "Why": Losing weight to "look better" usually fails. Losing weight so you can "lift your kids" or "have more energy for work" is a sustainable motivator.
- Be Transparent with Professionals: If you're struggling with metabolic issues, talk to a doctor. Whether it’s therapy for the mental side or medical support for the physical side, there’s no shame in using the tools available in 2026.
- Audit Your "Silent Calories": Meghan cut out the sugary lattes and sodas. Those 300-500 extra calories a day add up fast without ever making you feel full.
The "before" Meghan was a queen, and the "after" Meghan is a queen. The only difference is that now, she’s a queen who can pull a 200-pound sled and doesn't wake up in pain. That’s not a betrayal of body positivity—it’s the ultimate version of it.
