GLP-1 & body composition
Just started a GLP-1?
51% of prescribing physicians say muscle loss warrants better follow-up. Here's how to close the gap yourself.
The day our mom got her GLP-1 prescription, the appointment lasted about ten minutes.
We're Henry and Jackson, two brothers from Wyoming, and we were both in the waiting room that morning.
Her doctor checked her dose, walked her through the side effects, and set a refill date four weeks out. The next appointment was twelve weeks away.
She asked one question at the door. "Is there anything else I should be doing?"
"Keep your protein up and stay active," he said. "You're all set."
We don't blame our mom's doctor. He did exactly what the appointment was built to do. The problem is everything the appointment was not built to do.
By the drive home, she had a name for it: The 10-Minute Gap.
You already know a GLP-1 can cost you muscle. Everybody's warned you. Nobody equipped you.
Our mom got the warning too. She bought the protein powder, the meal prep boxes, the electrolytes.
That is not a criticism of the doctors. It is a description of the format. A 2026 review put it plainly: the strength and function checks the medical advisories call for are difficult or impossible to deliver through a telehealth-only visit. Not neglect. Format.
Medscape, 2026.
So the question is: who's tracking your muscle loss?
Every scale on the market can show you a number. None of them hand you a plan to act on it.
For seven months the weight came off. Fast. Every friend, every check-in, every appointment said she was doing amazing.
In month four she got into a pair of jeans she had kept for fifteen years. They fit, and the medication did that.
Those jeans were also the most detailed measurement anybody took of her in seven months.
Then one afternoon she tried to get up off the floor after playing with her grandkids. Her legs wouldn't do it.
She blamed the "dips in energy" everyone talks about on these medications. We blamed age.
It was neither.
She booked a session with the physical therapist she'd seen for hip pain earlier that year, so her old strength numbers were still on file.
He ran the same leg test he'd run in the spring, then stopped and asked her to do it again.
"When did this start?" he asked. She didn't have an answer.
Close to half the strength in her legs, gone.
And here's the scary part: in seven months of check-ins and refills, nobody in the system that prescribed her medication measured it once.
What gets checked
Not one of them tells you.
In the landmark trial that launched the GLP-1 category, researchers measured not just how much weight people lost, but what kind.
Other studies put it closer to 1 in 4 pounds. They disagree on how much. They agree it is a lot.
"For every two parts of fat you lose, you lose one of muscle. It's a fact."
Dr. Andres J. Acosta, Mayo Clinic, 2026.
When muscle goes, the tiredness that follows is the tiredness most people put down to the medication, or in our mom's case, "age."
What she put it down to
What it actually was
Muscle
Muscle burns energy while you rest, which makes it one of the most important parts of your metabolism.
When it drops, your body needs less food to hold the same weight, so the same effort buys you less every month.
The good news is: this works just as powerfully in the other direction.
If your muscle holds, the slowdown is smaller, and the whole thing gets easier from there.
The thing is, none of this was our mom's fault.
There is a specific kind of exhaustion that comes from doing everything right and having no way to know whether any of it is working.
She had that for seven months.
She wasn't failing to take care of herself. The support just didn't extend that far.
And this is the part we'd give anything to go back and change.
Think about the last time somebody in your family came home from a hospital.
They came home with a printed sheet. What to watch for. When to call. What should be getting better.
That sheet works because somebody decided in advance what mattered, and wrote it down before anything went wrong.

With a GLP-1
Leaflet
One of the most powerful medications in modern medicine, and that is everything that came with it.
It is not a mystery what she should have come home with. Four major medical organizations published it in 2025: a protein target, resistance training, and body-composition tracking. The advice exists. The follow-up that turns it into something you can do does not.
Joint Advisory: ACLM, ASN, OMA, TOS, 2025.
Now, maybe you're already taking steps to prevent muscle loss. Extra protein. Extra steps.
It's the right instinct, and it's where almost everybody stops. Fewer than half of people on GLP-1s reach the protein target that supports muscle maintenance, and average intake sits around 77 grams a day. Frontiers in Nutrition, 2025.
Not because they don't care. Because generic protein advice was written for people who can eat, and for the days right after a shot, that isn't the situation you're in.
And in a small 2025 study, the people who ate less protein in the first three months were the ones who lost more muscle. The instruction was right. The delivery wasn't.
Haines et al., ENDO 2025 · J Endocr Soc, 2025.
Without a plan built for a body that can barely eat, "keep your protein up" was never going to be enough.
Being warned is not the same as being equipped.
We couldn't fix it for our mom. So we built it for the next person. For you.
It's called the Orvi Protect & Grow System.
It's the follow-up nobody scheduled.
The Orvi Body Scan reads your whole body through 8 electrodes, measuring your arms, legs, and torso separately.
It's the same segmental configuration used in clinical devices.
You stand on it for ten seconds, and both numbers load on a simple app.
A home scale isn't a lab, and doesn't pretend to be. What it gives you is the honest weekly trend, so you always know which way your body is truly headed.
And if you're thinking you'd feel it happening, our mom didn't. Not for seven months.
The big-brand scale at the electronics store costs a lot more, and puts your own data behind a subscription paywall. And none of their products arrive with training and nutrition plans to protect your muscle.
Every Orvi Body Scan arrives with the follow-up the system never scheduled.
The complete version of the generic protein advice that prescribers float around. A full protein target for your stronger days, and soft, cold, easy protein on your lowest-appetite days. Every recommendation is backed by GLP-1 research, with the sources listed in the back.
The training plan every person on a GLP-1 deserves. It gives your muscle a reason to stay, from your own home, with a progression rule that tells you exactly when to go harder. Three sessions a week, about 30 minutes, bodyweight, band or dumbbell.
Changes what happens at your next appointment. It compiles your trends, your strength, your food and your symptoms into a one-page Clinician Summary you can hand across the desk.
And when your body is ready, the Grow and Power plans are built to help you build muscle back, not just protect it. No other system covers both phases.
Measure, fuel, protect. Then rebuild.
The question our mom asked at the door never really got answered, so she stopped asking it. Seven months later, a physical therapist answered it for her.
She wasn't overreacting. She was under-supported.
The difference between her story and yours isn't the effort. It's the tools.
For less than a single month of most GLP-1s, you can stop waiting for the system to catch up. Your baseline, how to hit your protein target, a training plan, and the trends that show all three working.
Try the whole system for 100 days. If it's not for you, email us and we'll organize a refund. The plans are yours to keep either way.
Nobody offers terms like that on something they have to talk you into.
And if you've read this far, you're not someone who waits to be handed what they need. You go get it. That's exactly who this was built for.
Less than a single month of most GLP-1 prescriptions.
Your prescription came with a dose.
The rest is up to you.
P.S. Our mom's appointments look different now. At her last one she slid a single page across the desk: three months of protein, training, trends and symptoms, all on one sheet. Her doctor read the whole thing, then asked her to email him her trend screenshots too. That page is inside every Progress Workbook.
P.P.S. The first morning takes about two minutes. Two numbers, written down, in your own hands. The tracking that should have been part of the prescription, now yours.
P.P.P.S. The gap doesn't close on its own. Your next appointment will cover your dose, your side effects and your refill date, the same as the last one. Everything after that is still yours.
