Meet Matt.
I'm Matt McCabe. This is the story of how nearly a decade of fighting the scale turned into an obsession with understanding food, fitness, and performance, and why I built Matt's Macros and Mero along the way.
Origin
I've struggled with my weight for most of my life.
Look at almost any old photo of me and chances are, the cheeks were out.
In my family, food has always meant love, connection, and comfort. I leaned into that, and somewhere along the way, I also became a pretty good cook.
While my friends were playing sports or video games, I was the band kid watching YouTube videos about French cooking techniques. I played basketball and always managed to make the team, but rarely saw the court. And, to be fair, that was on me.
As a teenager, I often made dinner for myself and my family. I experimented, screwed things up, tried again, and learned how to cook.
At the same time, I was very aware of my weight.
I spent nearly a decade trying to change my body. I'd lose weight, gain it back, and repeat the cycle. The scale moved constantly. I knew how to lose weight, but I didn't understand how to build a way of eating and training that I could actually sustain.
The platform, chapter one
Matt's Macros
Matt's Macros started in 2022 as a way for me to reclaim ownership over my own body.
What began as counting macros became a lifelong experiment with a much bigger mission: figure out what health and fitness mean to me, then share everything I learn along the way.
The wins. The failures. The experiments that work and the ones that don't.
Tracking macros changed the way I understood food. For the first time, I stopped looking at individual foods as inherently “healthy” or “unhealthy” and started looking at the choices I made in the context of my goals.
And because I already loved to cook, I started applying what I knew about different cuisines, ingredients, and techniques to the way I ate.
The goal wasn't to make “diet food.”
It was to make food that was bold, satisfying, approachable, and capable of supporting what I wanted my body to do.
The shift
From weight loss to performance.
Over time, my definition of fitness changed too. It stopped being exclusively about what I looked like and became much more about what I could do.
- Could I get stronger?
- Could I run farther?
- Could I recover and do it again tomorrow?
- Could I fuel ambitious training without making food and fitness consume my entire life?
That shift eventually took me from someone who spent years fighting the scale to completing my first 50K ultramarathon.
And I'm just getting started.
The philosophy
HungerDriven.
The pursuit of both.
For a long time, food and fitness felt like competing interests. Loving food made it harder to look the way I wanted. Pursuing fitness meant restriction. Progress meant saying no.
Now they reinforce one another.
I can love food and care deeply about my nutrition. I can chase ambitious physical goals without treating eating like a necessary evil.
Food can be:
- Love.
- Connection.
- Comfort.
- Fuel.
And hunger can represent both appetite and ambition.
- Eat with intention.
- Train with purpose.
- Stay hungry for whatever comes next.
The platform
Building something bigger.
In 2025, I began turning Matt's Macros into a platform where I could share what I was learning with other people.
I'm not interested in miracle foods, demonizing ingredients, or pretending there's one perfect diet. My goal is to build practical tools that help people understand their nutrition and figure out what works for them.
Because no two people are exactly the same.
The system
Then came Mero.
Nutrition is easier when you plan before you're hungry.
In 2026, I founded Mero to turn that idea into a system.
Mero takes your goals, nutrition targets, and training demands and turns them into a weekly eating plan. Instead of asking you to spend every day logging what you already ate, Mero helps you decide what you're going to eat before the week begins.
- Plan
- Shop
- Prep
- Cook
- Eat
- Adjust
Whether you're trying to lose a few pounds, build muscle, fuel an endurance goal, or simply stop improvising your nutrition every day, the objective is the same: create a system you can actually execute.
It's an evolution of the same system I've been building for myself since 2022, the one that has helped me reach the best shape of my life, support a rigorous training schedule, and finish my first ultramarathon.
Ongoing
This is an experiment.
I don't have health and fitness completely figured out. That's kind of the point.
Matt's Macros is a record of the process: learning, testing, cooking, training, failing, adjusting, and getting better.
There's no finish line to health and fitness. You keep learning as your body, goals, and life change.
I'm glad you're here.

How I do the work
- Recipe testing
- Every recipe is cooked in my own kitchen at least once before it ships, with macros reconciled from label data on the actual ingredients I used.
- Macro sources
- Ingredient macros come from USDA FoodData Central or the packaged product's nutrition label, not from a generic recipe database.
- Calculator methodology
- Formulas and dose ranges cite the modern sport-nutrition literature (Mifflin-St Jeor for BMR; Burke, Jeukendrup, and the ACSM/AND/DoC 2016 joint position for carb loading).
- Limitations
- I'm not a registered dietitian and this site is not medical advice. If you have a clinical condition or a competitive weight-class goal, work with a qualified professional.
