GLP-1 & body composition
About to start a GLP-1?
We watched our mom lose 32 lbs. Then found out what she'd really lost.
If you're about to start, you still have it all ahead of you. Here's how to do it right.
Before your first dose of GLP-1, we need to tell you about our mom.
We're Henry and Jackson, two brothers from Wyoming.
This is the story of the seven months we spent celebrating the wrong number.
Seven months of winning
Our mom started on Wegovy at 56.
After twenty years of diets that never held, the weight finally came off. Fast.
Every friend, every doctor, every check-in said she was doing amazing.
The scale kept dropping. We all kept cheering it on.
7 months in. 32 lbs down.
She started to feel different. Tired. A little weaker. The stairs in her own house left her breathless.
One afternoon she tried to get up off the floor after playing with her grandkids. Her legs wouldn't do it.
"Just give me a minute," she said, and made it sound like a joke. She needed the couch to pull herself up.
She blamed the "dips in energy" everyone talks about on GLP-1s. We blamed age.
It was neither.
The one thing nobody was measuring
She booked a session with her physical therapist. The one she'd seen for hip pain earlier that year, so her old strength numbers were still on file.
He ran the same simple leg test he'd run in the spring. Then he stopped, and ran it again.
"Are you feeling okay today?" he asked. "Just tired," she replied.
He set the two results side by side.
She had lost close to half of the strength in her legs.
Half. In seven months. While every number she tracked told her she was winning.
The scale had cheered her on the whole way. It only ever knew one thing: that she weighed less.
She had no idea a huge share of what she'd lost wasn't fat at all.
It was muscle.
You might be thinking it's too early to worry about this. You haven't even started.
That's exactly why now is the moment.
The people who keep their muscle are the ones who started protecting it before they lost any.
We read everything
We read every study we could find on GLP-1 muscle loss.
Here's what we wish our mom knew before she filled that first prescription.
This isn't rare. It's common.
The medication switches off your appetite. You eat far less. Your body hunts for energy.
Muscle is energy. So your body breaks down what you spent your whole life building.
By the time you notice, it could have been happening for months.
The medication does exactly what it promised. It takes the weight off.
It's up to you to protect your muscle.
And maybe you're already planning to. Extra protein. Some walking. Our mom's doctor mentioned protein too.
Without a way to see her muscle, "eat more protein" wasn't enough.
Fat and muscle don't do the same thing
Here's the part that made it all click.
A pound of fat and a pound of muscle weigh exactly the same. Your scale just adds them together and shows you one number.
But fat and muscle could not be more different.
Fat mostly just sits there. Stored energy, waiting.
Muscle is the active part. It's what your body runs on. It keeps you strong, steady on your feet, able to get up off the floor without thinking.
It runs your metabolism, and it's the reason the weight stays off later.
Fat loss is the goal.
Muscle loss is the part you need to measure the most.
Lose too much of it and you don't just get smaller. You get softer. Weaker.
You can hit your goal weight and still feel worse than the day you started.
And when you stop the medication, the weight is likely to come back, as fat.
Here's the good news.
None of that is fixed. It comes down to the signals you send your body from the start.
None of this was her fault
Her whole life, when something went wrong with her body, she blamed herself. Not enough willpower. Not enough discipline.
This was not that.
You can't protect what you can't see.
Nobody ever gave her a way to see it. Her scale couldn't. And her check-ins didn't cover body composition.
That's not a personal failing. It's a gap in the system.
The one advantage our mom never had
You've probably already seen the warnings about muscle.
Knowing the risk isn't the same as being able to see it. Or act on it.
You only get one chance to start this right.
Our mom started blind. By the time anyone measured, seven months were already gone.
You get to see it from the very first morning. With a plan to protect your muscle.
We built what we wish she'd had
We couldn't fix it for her. So we built it for the next person. For you.
It's called the Orvi Protection System.
It does the one thing her scale never could. And it gives you the tools to protect your muscle.
It shows you exactly what kind of weight you're losing, at home, every single morning.
Not a guess. Not a clinical scan you schedule twice a year. Not a cheap scale that reads your legs and guesses the rest.
The Orvi Body Scan reads your whole body through 8 electrodes, measuring your arms, legs, and torso separately. It's the same 8-electrode configuration used by clinical InBody devices.
You stand on it for ten seconds each morning. Fat and muscle, side by side, in a simple app.
It was never about a perfect lab number. A scale at home isn't a lab, and doesn't pretend to be.
What it gives you is the honest trend. Fat moving one way, muscle the other, so you always know which way your body is truly headed.
But seeing it isn't enough
Knowing your muscle could slip doesn't protect it.
So every Orvi Body Scan arrives with the plan our mom was never given.
The Orvi Fuel Plan sets your protein target from your goal weight, then breaks it into three daily protein anchors you can actually hit. Built for GLP-1 appetite from page one: soft, cold, no-cook protein for the hard days, your full target on the good ones.
The Orvi Protect Plan is 12 weeks of resistance training built to give your muscle a reason to stay. Three home sessions a week, about 30 minutes. Every exercise has a bodyweight, band, and dumbbell version, and there's a 20-minute short session for your hardest days.
And the Orvi Progress Workbook starts where you are: a ten-minute baseline of your weight, fat, muscle, and strength, written down before your first dose. From day one, every trend you see compares against it.
Measure, fuel, protect. That's the Orvi Protection System, and the workbook is where it all adds up.
You could try to assemble this yourself. A scale from one place. A protein plan from another. A workout off YouTube.
We tried, for our mom. Nothing was built to work together for a body on a GLP-1. Nothing starts you with a baseline, a protein target, and a training plan that already knows what shot weeks feel like.
So we built it as one system. Only Orvi puts all of it in your hands before your first dose.
It's also where the science points: eat more protein, train with resistance, protect your muscle.
Picture your own month seven.
The weight is coming off, and you know exactly what's leaving. Fat down. Muscle holding.
No guessing. No quiet worry about what the scale isn't telling you. No surprise waiting at a physical therapist's office.
Just the calm of knowing you did this right, from the first morning.
You're reading this in time
If we could go back, we'd have set our mom up with this on day one. Not seven months later, after the damage was done.
Before the first dose, while everything was still ahead of her.
She uses the system herself now. Every morning, ten seconds.
At her last check-in, she put her phone on the desk and showed her doctor three months of trends. Fat one line, muscle the other, with her workbook log to back it up.
He looked at it for a long moment. Then he asked her to email him the screenshots.
The appointment that never checked her muscle now asks for her numbers.
You have something she didn't. You're reading this before you start.
You're joining 31 million Americans on these medications.
You get to be one of the few who do this right from the start. Not the easy way. The smart way.
There's no shame in using every tool you can to protect your body.
For less than a single month of your medication, you start with what our mom never had: your baseline, your protein target, your training plan, and the trend that shows all three working.
Try the whole system for 365 days.
