The bathroom scale
Swings with water, salt and last night's dinner
Can't tell fat from muscle
Same weight for 3 months. That doesn't mean nothing changed.
Your scale shows one number. BodyFit breaks it down into fat and muscle, so you can see what your training is actually doing.

- Carnivore
- Sixteen-eight
- Three days a week
- Six days a week
- Cut carbs
- More protein
Nobody is telling you this
Every voice online is certain, and none of them agree. You picked a lane anyway. You trained. You showed up.
Then nothing changed, or nothing you could see. The usual answer is your age, or your metabolism.
You've been flying blind.
How do you actually measure your progress?
Every method you've tried gives you a reading. None of them give you the one that matters.

BMI
Weight divided by height. It can't tell muscle from fat.
Same number, any body
Here's the thing none of those methods could ever tell you
Real progress is your body's actual composition, specifically, whether you're building muscle at the same time you're burning fat. That's the one shift that tells the truth, because muscle only changes in direct response to real, sustained effort.
So here's the actual answer to why it doesn't show: you've been training hard, but you haven't been measuring the one thing your training actually changes.
Regular scale
Feet and legs, the rest is estimated
BodyFit
Current runs through your whole body
The shift the scale can't show you
Fat and muscle moving in opposite directions, the same shift a regular scale misses.

You train hard.
So why doesn't it show?
Real progress is body composition: building muscle while you lose fat.
The scale can't see that shift. So the work is happening, and you have no way to see it.

Average fat loss of 2.25 lbs among 115k Body Scan users over a 90-day period. Individual results vary; outcomes depend on diet, activity, baseline composition, and overall health.

Beyond your weight
40+ biomarkers from one 20-second weigh-in. Here's what else you'll see.
BMR
Your basal metabolic rate shows how many calories your body burns just to keep running, even before you move a muscle
Visceral Fat Index
This tracks the fat stored around your organs, the kind you can't see in the mirror but that matters most for your health
Metabolic Age
Metabolic age compares how efficiently your body burns energy to your actual age, so you can see if the two are lining up
Total Body Water
This shows how hydrated your body actually is, which often explains an energy dip before hunger or tiredness does
Steps
Your daily step count, tracked automatically, so you know how much you're really moving beyond your workouts
BMI
Your body mass index, one more number for the full picture, read together with everything else instead of on its own
Weight Trend
Your weight trend smooths out the daily noise, so you see where you're actually headed, not just today's number
Muscle Mass %
This shows how much of you is muscle, so you can see it holding steady even while your weight moves.
Fat Mass %
This shows how much of you is fat, tracked apart from muscle, so a stalled scale doesn't tell the whole story
Lean Mass
Everything that isn't fat, muscle, organs, water, bone, tracked together so you see the fuller picture of what's changing
Skeletal Muscle Mass
The muscle you can actually build and lose, tracked apart from your organs and everything else
Bone Mass %
Your bone mass, tracked over time, so you know it's holding steady while everything else changes
Trunk Fat
Fat stored around your midsection, read on its own instead of blended into one number for your whole body
Trunk Muscle
Core and torso muscle, tracked apart from your arms and legs, so you see exactly where you're building
Leg Fat
Fat in your legs, read separately from your trunk and arms, so you know exactly where change is happening
Leg Muscle
Leg muscle, tracked on its own, so leg day actually shows up somewhere besides how sore you are
Arm Fat
Fat in your arms, read apart from the rest of your body, for a shape picture no bathroom scale gives you
Arm Muscle
Arm muscle, tracked separately, so you can see it building even when your overall weight barely moves
Vascular Age
Compares the flexibility of your arteries to your actual age, one more number for the years ahead
Standing Heart Rate
Your heart rate the moment you step on, a quick daily check on how your heart is doing
Leg Pulse Wave Velocity
How fast blood moves through your legs, a marker your doctor may already track for heart health
Arm Pulse Wave Velocity
How fast blood moves through your arms, read alongside your legs for a fuller cardiovascular picture
PWV Differential
Compares your legs to your arms, a gap that can say more than either number alone
Nerve Response Score
A read on how your nerves are responding, one more signal for your long term health
What you measure, you can change.
What 66,875 Withings users learned and achieved in 6 months.*
2×
Users who step on their scale daily lose more than twice as much fat as those who weigh in weekly.
1 in 4
Users over 40 discovered a hidden muscle deficit, at least 5% below average for their age.
4 in 10
Withings+ users found their vascular age was older than their real age. Invisible without measuring.
*Based on 66,875 Withings+ users who weighed in daily over 6 months. Individual results vary.
Real people, real progress
I was super grateful for the visual breakdown of metrics for each part of my body and it helped me to immediately understand how I am doing related to my health goals.
Compared to a DEXA it was within 2% on almost all metrics of body composition which I consider pretty good.
Lost 25 lbs and dropped 11% body fat in the first months of use. I had 187lbs and 33% down to 162lbs.

What are BodyFit's main innovations compared to other smart scales?
BodyFit goes far beyond a traditional smart scale. Powered by 8 electrodes and BIS technology across 13 frequencies up to 800 kHz, it delivers a precise, 6-zone segmental view of your body composition, something most scales simply can't offer. A high-resolution color LCD screen makes your key metrics instantly readable, right on the scale, no phone needed.

Why do I need to hold the handle during measurements?
The handle is what makes segmental analysis possible. When you hold it, the electrical current travels through your entire body, arms and torso included, giving BodyFit the data it needs to analyze each segment individually: right arm, left arm, right leg, left leg, and trunk. Without the handle, that full-body picture simply isn't possible.
Can multiple people use BodyFit?
Absolutely. BodyFit automatically recognizes up to 8 different users, each with their own profile and personal data in the Withings App. No manual switching needed.
Is the Withings App free?
All your essential data is available in the Withings App at no cost. If you want to go deeper, Withings+ is an optional premium subscription that unlocks AI-powered daily guidance, exclusive health scores, and richer personalized insights to support your journey.
How accurate is BodyFit compared to a DEXA scan?
BodyFit's fat mass readings show a 99% correlation with clinical DEXA scan results.¹ Individual results may vary, and BodyFit is not a medical device for diagnostic purposes.
I'm losing weight with a GLP-1 medication. Can BodyFit help me?
Yes. If you only track your total weight, you might be celebrating muscle loss. BodyFit tracks your muscle mass percentage daily, so you can see if you're losing muscle along with fat and adjust with your doctor or nutrition plan.
