You Lost 20 Lbs. But How Much Was Muscle? About to Start a GLP-1? Set Your Baseline First. Your Scale Sees the Weight Loss. Not the Muscle Loss.
Clinical trials show: up to 40% can be muscle. Your scale shows one number. It can't tell the difference.
Your bathroom scale misses everything that matters on GLP-1.
Set your baseline before you start.
Up to 40% of GLP-1 weight loss is muscle, not fat. Your scale doesn't track it. Now you can.

What the Scale Can't Show You
Ted Lost 20 Lbs on Wegovy.
He was thrilled. The scale kept dropping. Then he got a DEXA scan.
He'd gotten one just before he started, 2 months earlier, and had some baseline measurements.
Only 8 of those 20 lbs were fat. The other 12 were lean mass. Even his doctor was shocked.
Ted's story isn't rare. The clinical evidence says it's the norm.
40%
of weight lost may be muscle.

"I've treated dozens of women who lost muscle just as fast as Ted did. One of them only found out when their knees went."

You feel it before you see it.
Weakness. Fatigue. Softer arms.
If you catch it early, you have a chance to stop it. If you don't, rebuilding can take years.
We built Orvi so nobody has to go through what Ted did.
The Scale Problem
The Scale Doesn’t Show You.
Lighter on the scale.
Softer in the mirror.
Weaker on the stairs.
Your bathroom scale tells you the only thing it can: total weight. Fat, muscle, bone - everything - in one number.
How much do I weigh?
... is the wrong question.
You should be asking:
What kind of weight am I losing?
"I'm softer, not leaner."
"I feel deflated and emptied out."
"I can feel my muscle going."
"I don't know if I'm losing muscle."

Rapid weight loss can also change facial fullness. In a 2024 Clinical Case Series article, doctors noted:
"Muscle loss in the face is particularly concerning as it is nearly impossible to regain naturally."

"I kept seeing people say to track body composition from the start, so I ordered the Orvi body scan 2 weeks before my 1st shot. Best decision ever. It showed me that I was losing more muscle than fat about 3 weeks in so I upped my protein and went harder on my workouts. 11 weeks in now and everything's going great!!"

Why Not Just Get DEXA Scans?
There are four ways to track weight loss on GLP-1s. Only one gives you daily fat and muscle trends at home.
| Bathroom Scale | Generic Smart Scale | DEXA Scan | Orvi | |
|---|---|---|---|---|
| See fat vs muscle | ✗ | ✓ | ✓ | ✓ |
| Every day, at home | ✓ | ✓ | ✗ | ✓ |
| Easy trend tracking | ✗ | ✓ | ✗ | ✓ |
| Made for GLP-1 journeys | ✗ | ✗ | ✗ | ✓ |
| Cost | $20–30 | $30–250 | $45–$150/visit | $149 once |
To be honest: We’ll never claim to match DEXA for a single reading. No home scale can. We deliver reliable trend data. Fat and muscle trends over 90 days tell you more than quarterly scans ever could. DEXA gives you a snapshot. Orvi gives you the full picture.

What People Are Saying About Orvi

"I lost 30 pounds and looked fluffy, not toned. My hair started falling out. Turns out I was losing the wrong kind of weight."

Personally on Mounjaro
I'm 56 and not a tech person AT ALL, so I got my daughter to set the app up for me. I've been on Ozempic since Jan and didn't even know muscle loss was a big deal until I saw this scale mentioned in my support group. In the first week the app showed my muscle was dropping and I nearly cried. Luckily me and my doc made a plan to keep what I have and it's working!! Now the scale just gives me peace of mind.

I was skeptical about Orvi since body comp scales can be inaccurate.. but my husband pointed out that the trends are what matter. Been using it for 3 months and it caught my muscle dropping a few weeks ago so I started working out more and it's already turning around. Really feel in control.

6 weeks on Zepbound and the scale barely moved this week. I would have spiralled before, but this showed me my fat is still going down and my muscle is holding. It's amazing how much easier it is when you can see what's actually happening in the app!

Lisa Walsh Stall weeks are so much easier now. When the scale stops I just check the fat trend vs muscle and it's still reassuring

Why We Built This
31 million Americans are on GLP-1s. Most of them are lacking the tools they really need.
We're Henry and Jackson. We run a small team in Wyoming. We started Orvi because our Mom lost 32 lbs on Wegovy, and was told by everyone she saw that she was "doing brilliantly." Then - eight months in - her new physiotherapist told her she'd lost nearly half her lower-body strength.
She was 57 at the time. Her scale had been telling her she was succeeding the entire time. Her doctor had been telling her the same thing. Nobody was measuring what actually mattered.
She wasn't a clinical rarity. She was an average GLP-1 patient, losing fat and muscle, with no one tracking her body composition, and no tool at home to track it either.
So we built one for her, and the 31 million other people on these medications right now who deserve to know what they're actually losing - while there's still time to do something about it.
This isn't a generic fitness scale. It's the tool we wish our Mom had from day one.

Common Questions
I haven't started my
GLP-1 yet. Should I wait?
GLP-1 yet. Should I wait?
No. The opposite. Your most valuable baseline reading is the morning of your first shot. Once your body composition starts changing, you can never go back and measure that day-zero reference point.
What app does Orvi use?
Orvi connects through the Unique Health app, our trusted partner app for body composition trend tracking. It is available on iOS and Android and can sync with Apple Health and Google Fit.
How accurate is Orvi compared to DEXA?
No home scale matches DEXA for a single reading, and we'll never claim otherwise. What Orvi gives you is consistent trend data. The direction your fat and muscle are moving over weeks matters more than one isolated reading.
What about facial changes after rapid weight loss?
We cannot diagnose, treat, or reverse facial changes. What we can do is show you how quickly you're losing fat and muscle. Then, with protein, resistance training, and help from your doctor, you can make the adjustments to protect your muscle.
Is this the same as a cheap Amazon scale?
No. Orvi uses an 8-electrode configuration with a handheld bar. It measures across your arms, legs, and trunk, instead of estimating everything from foot-to-foot readings. It is also backed by a lifetime hardware warranty.
I already have a bathroom scale. Why do I need this?
Your bathroom scale shows one number: total weight. Orvi helps you see whether the weight you are losing is trending from fat or muscle. On a medication that can cost hundreds or thousands of dollars, that distinction matters.
I'm already months in. Is it too late?
No. Your current body composition becomes your new baseline, and every reading from this point forward tells you the direction you are moving. The best time to start was day one. The second best time is now.
Is there a subscription?
No. You pay $149 once for the scale, and the Unique Health app is free, forever. No monthly charges.
What if I decide it's not for me?
We provide a 365-day guarantee on every order. If Orvi has not told you more than any scale ever has, email us. Full refund to your original payment method. No restocking fee.
What if I stop taking my GLP-1?
Tracking body composition still matters during maintenance. If weight comes back, you want to see whether the trend is mostly fat, muscle, or both, while there is still time to act.
When will my scale arrive?
7 to 14 days from order. Free shipping across the US. You'll receive a tracking link the moment your order ships.
