Meghan Trainor — the “All About That Bass” singer known for her body positivity message — made headlines in 2025 after revealing a dramatic physical transformation. She lost approximately 60 pounds using a combination of Mounjaro (a GLP-1 medication), a dietician-guided high-protein diet, and weight training three times a week.
What made her story unique: she and her husband Daryl Sabara did it together — both taking the lowest dose of Mounjaro simultaneously while working out and eating right.
Here’s exactly what she did, what she eats, and the recipes that align with her approach.

Meghan Trainor’s Weight Loss Story
After the first pregnancy (2021)
After welcoming her first son Riley in 2021, Meghan lost 60 pounds the traditional way — through diet, exercise, and consistency. “I did it the healthy way, the long way, the one pound a week way. And it’s a proud accomplishment that I never thought I could ever do,” she told People in 2023.
At her heaviest during that period, she weighed around 200 pounds. “I was my heaviest I’d ever been. I just wasn’t feeling great.”
After the second pregnancy (2023)
After her second son Barry was born in July 2023, she gained weight again — and this time also received a gestational diabetes diagnosis during the pregnancy. That health scare became a motivating factor for taking a more medically supervised approach.
“I was in a really dark place, and I wanted to be in a great place for my son,” she said.
The Mounjaro revelation (March 2025)
After being honored at the 2025 Billboard Women in Music Awards, Meghan was frustrated that most questions focused on her body transformation rather than her decade of musical work. She took to Instagram to set the record straight — and to be fully transparent.
“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.”
The couple approach
What sets Meghan’s story apart: she and her husband Daryl Sabara started the journey together. During an April 2025 episode of their joint podcast “Workin’ On It,” both confirmed they were taking Mounjaro at the lowest possible dose.
“We stay in the gym, we work out, we eat right, and we just noticed that we were less hungry,” they shared. “Daryl and I both do everything together.”
How Meghan Trainor Lost the Weight — The 4-Part Method
1. Mounjaro (lowest dose, medically supervised) After researching GLP-1 options with her doctor, Meghan chose Mounjaro over Ozempic because she felt it “had less side effects.” She emphasized it was a supplement to her lifestyle changes, not a replacement.
2. Dietician-guided high-protein meals She worked with a professional dietician to restructure her eating habits. Her diet consists of protein and carb-balanced meals, often from meal delivery services that make healthy eating sustainable on a busy schedule.
3. Weight lifting 3x per week Meghan credits weight training as the key to changing her body composition — not just the number on the scale. “I’ve never been so fit,” she said in January 2025. Her sons even watch her work out and have their own toy weights.
4. Mindset shift — health over appearance “I want to run and keep up with my kid. I want to be able to put on a bathing suit and run out there and not be in my head about it.” Her motivation was health and energy for her children, not aesthetics.

|---|---|
| General approach | High-protein + balanced carbs |
| Meal prep | Meal delivery services for structure on busy days |

Recipes That Fit Meghan Trainor’s High-Protein Approach
Recipe 1 — Pre-Meal Appetite Control Gelatin Drink
The same GLP-1 mechanism that makes Mounjaro effective can be naturally stimulated through diet. Glycine — the dominant amino acid in gelatin — triggers natural GLP-1 production in the gut. This drink taken before meals supports the same appetite-suppression Meghan gets from Mounjaro, at a natural level.
Ingredients:
- 1 packet (7g) unflavored gelatin
- 1 scoop unflavored collagen powder
- 1 cup warm water
- Juice of ½ lemon
- 1 pinch pink salt
Instructions: Bloom gelatin 2 min → stir until dissolved → add collagen + lemon + salt → drink 20 min before meals.

Instructions:
- Cook brown rice according to package

The Body Positivity Paradox
There’s an irony not lost on Meghan’s fans: the woman who sang “All About That Bass” — one of the most iconic body positivity anthems of the 2010s — is now publicly discussing her weight loss journey and medication use.
Meghan has addressed this directly. Her position is nuanced: body positivity means accepting yourself AND pursuing health on your own terms. “I don’t want them to hear me ever being mean to my body,” she said of her sons. “I don’t want them to do that to themselves.”
Her frustration at the Billboard Awards was precisely this point — that even in 2025, a woman being honored for a decade of musical achievement is still primarily asked about her body.
