¹Combined overweight (BMI 25.0–29.9) and obesity (BMI ≥30) prevalence among US adults 20+. CDC NCHS, NHANES 2017–2018 (most recent published combined data). 42.5% obesity + 31.1% overweight = 73.6%, reported as ~74%.
As Seen In
They're fighting a system designed to beat them.
Every time you eat less, your body slows down to match. The deficit that worked in week one produces half the result by week six. Your plan never had a chance.
Calorie restriction raises ghrelin - making you hungrier - while lowering leptin, making satisfaction harder to reach. You are not imagining it. It is biology.
Every failed attempt reinforces the pattern. You try harder, your body adapts harder, the scale doesn't move, you stop. Then you start again from a worse position.
Without a signal that it's working, even the most determined person eventually stops. Not from weakness. From silence.
BodyFit turns invisible momentum into something visible every morning. The data was always missing. Now it isn't.
Daily scale users lose 2x more fat than weekly scale users
*Based on 164,000 Withings users over 90 days. Daily weigh-ins (≥65 of 90 days) averaged 4.8 lbs of fat loss; weekly (8–18 days) averaged 2.1 lbs. Observational; individual results vary.
Weight fluctuates daily. Measuring it alone is like judging a race by the starting gun.
BodyFit separates muscle gain from fat loss, so every morning shows exactly what's changing. This is the process that makes quitting impossible.
Half of women "stuck" on the scale were actually losing fat. Their scale just didn't show it.
*Based on 115,000 Withings users over 90 days. Among women whose total weight changed less than 1 lb, 53% measured fat loss averaging 2.25 lbs.
Advice without data isn't medicine. It's guessing.
BodyFit generates data so precise the next doctor's appointment becomes a conversation worth having. Walk into your next appointment with data your doctor can use.
1.6 million people share their data with their doctor
* Based on all Withings app users who triggered health report features.
Important: BodyFit is a wellness device, not a medical device. The data is for self-tracking and is not a substitute for clinical measurement, medical advice, or diagnosis.
Every generic programme is built for a fictional average person. A person who does not exist.
BodyFit recalibrates to actual body composition every single morning. For the first time, the plan fits the person.
8 in 10 people who lose weight also lose muscle
*Based on 542,000 Withings users over 90 days. Among users who lost at least 2 lbs of total weight, 82% also lost muscle (averaging 3.55 lbs of muscle loss).
Without a map of what's happening inside, every result feels random. And random results drive anyone insane.
BodyFit's full-body map shows exact fat distribution, region by region, updated every morning. Once the inside is visible, the guessing stops.
1 in 3 scale users discover they actually carry more body fat than WHO recommended.
*Based on 766,000 Withings users in their first month. Thresholds applied: 25% for men, 35% for women - commonly referenced statistical thresholds, not WHO standards.
Every tool tracked the outside. They focus on activity, food, and movement. None of them could see in.
BodyFit focuses on body composition.
1 in 2 Apple Watch users whose weight barely moved lost 3.3 lbs of fat and gained muscle.
*Based on 3,900 Withings+ users over 180 days. Among Apple Watch users whose total weight changed less than 1.5 lbs in their first 90 days, 53% lost an average of 3.66 lbs of fat in the next 90 days, with small muscle gains alongside it.
No one can say what's working without seeing inside the body. Now something can.
Withings Health Assistant reads your personal data to know what's working for your body. Ask it anything and get answers that actually apply to you - not generic advice pulled from the internet.
Every weigh-in becomes a conversation worth having - with your data, your app, and your doctor.
Users who stayed consistent on weekends lost twice as much fat as those who skipped.
*Based on 1.3 million Withings users over 90 days. Weekend-consistent users (≥18 of 26 weekend days) lost an average of 4.0 lbs of fat; those who skipped weekend weigh-ins lost about 2.0 lbs.
But they're flying blind…
And for most Americans, none of it is working.

Real measurements*
* Based on 66,875 Withings users who weighed in daily over 6 months. Individual results vary; outcomes depend on diet, activity, baseline composition, and overall health.
Most scales measure one thing: how hard gravity is pulling on you. BodyFit measures 40+ signals across your entire body - arms, legs, and torso separately - and turns them into a single honest picture of what's actually changing.
Validated against the imaging standard used in clinical research.
Arms, legs, and torso measured separately. Because where matters as much as how much.
Step on. Hold the handle. Done.
Fifteen years of medical engineering in your bathroom.
No phone needed during the scan.
*Internal comparative study between Withings BodyFit measurements and DEXA scan results. 99% correlation observed on fat mass results. Individual results may vary. BodyFit is not a medical device for diagnostic purposes.
BodyFit doesn't just read your body. It tells you what to do next.
BMI, lean mass, visceral fat, and skeletal mass in a single honest signal.
Your vascular age and standing heart rate, every morning, no wearable needed.
Tracks the metrics that matter most on medication-assisted weight loss.
Goes beyond BMI to show what your body is truly made of.
Every weigh-in automatically generates a body composition report you can bring to your next appointment - fat mass, muscle mass, visceral fat, Vascular Age, and cardiovascular indicators, tracked daily. Not a screenshot. Not a number you typed into Notes. A complete report, from a device used by over 1 million people who actively share their data with their healthcare providers.*
Walk in with months of body composition data. Walk out with a conversation grounded in what's actually been happening - instead of a best guess based on how you felt in the waiting room.
1.6 million Withings users already share their data with their healthcare provider
*Based on all Withings app users who triggered the in-app health report feature. BodyFit data is for self-tracking and is not a substitute for clinical examination, laboratory tests, or medical advice.
Most scales tell you one number. That number doesn't tell you if you're losing fat or muscle, whether your cardiovascular signals are changing, or whether anything you're doing is actually working. BodyFit does all of that. Before breakfast.

OUR STORY
Most health technology companies are built by investors looking for an exit. Withings was built by an engineer who couldn't stop caring about the problem.
In 2009, Eric Carreel built the world's first connected scale.
He saw a device that hadn't changed in a hundred years - step on, get a number, step off - and decided that wasn't good enough.
So he built something better. And in doing so, invented the entire category.
In 2016, Nokia bought the company.
In 2018, Eric bought it back.
Not because it was a smart financial decision. Because the work wasn't finished. Because ten million devices in real homes, and over a million people who actively share their data with healthcare providers, deserved a company still run by someone who cared what happened to them.
BodyFit is the most personal product he's ever built. Designed for the people deserving to see what's actually changing. That's who this was always for.
REAL REVIEWS
A renowned San Francisco aquarium biologist was mortified to discover he weighed the same as his 6-foot-tall magician friend Penn Jillette, despite being nearly a foot shorter.
The Withings scale created automatic daily accountability by emailing his weight to Penn and two other friends, making it nearly impossible to slack off.
A competitive cyclist in Austin had hit a frustrating plateau despite riding regularly, realizing that performance gains on the bike were inseparable from his weight. Daily weigh-ins on his Withings scale gave him frictionless data tracking that made the connection between food choices and on-bike performance undeniable.
A tech-loving Honolulu transplant raised on West Virginia "country cooking" stepped on a scale he'd bought as a gift for his wife and was so shocked by the number that he overhauled his entire life.
The Withings scale became the catalyst and ongoing tracker for an 87-pound weight loss, a near-halving of his resting heart rate, and a completed marathon.
Struggling to breathe after bending over to tie his shoes without a chair, Abdon had a visceral moment of realization that his health had quietly slipped beyond a point he could ignore.
The Withings Health Mate app gave him a place to document goals and see measurable progress, providing the focus and accountability that kept him on track.
A Family Guy voice actor and world-famous karaoke host had let weight creep up unnoticed — then a colon cancer diagnosis, caught early because the ACA required him to get his first checkup in a decade, made health non-negotiable.
The Withings scale turned daily weigh-ins into a game-like feedback loop — a dropping graph line gave him the same motivational rush as a high score.
A tech-loving, globally-minded cook who'd struggled with his weight since age 12 hit a wall at 220 pounds where no amount of exercise was moving the needle.
Combining his Withings scale with the Lose It! app finally surfaced the 80% food variable he'd been missing, unlocking real weight loss and eventually a grueling obstacle race.
A former serviceman turned homeless veterans advocate watched his weight climb to 250 pounds under the stress of a sedentary, high-pressure job — and hated the person he saw in the mirror.
The Withings scale's integration with Lose It! gave him the honest daily data and routine that matched his disciplined personality, and his transformation now gives him credibility when encouraging the vets he serves.
Tom was pre-diabetic with high cholesterol and a needed hip replacement; Alisa was a smoker who could barely pedal a stationary bike — and they decided together that pills and deterioration weren't the path forward.
Tom gave Alisa a Withings scale for Christmas, and the combination of the scale and Lose It! became the shared accountability system that helped them collectively drop 120 pounds and rack up millions of lifetime steps.

We’ve only had it two days so it’s hard to give great feedback but I love seeing the #DATA. I’m not sure what I expected by. I expected it to do more. Have more data and more info. Like when it says it tracks over 40 biomarkers or something like that I feel like I see five things in the app.

Looks good, feels solid and well built. Time will tell accuracy and effectiveness which is most important for me however first impressions are good.

The device is heavier than our other Withings Scale (Body+), feels like it is more solidly built, and I like that it is USB-C rechargeable and that the reset button has moved to the side.

Seems to be a quality piece of equipment. I’m looking forward to using it.

It's awesome not having to doubt the fat percentage number anymore. My old scale the number varied more than my weight so it was hard to get a real feeling of where I'm at and how I'm trending - in less time than my old scale too.

I love the clarity of the numbers on the scale. Easy to read and doesn’t take much space.

This scale checked exactly all of the boxes I was looking for. Rechargeable with quality hardware and featuring segmental body composition measurement. Being my first with this feature, 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.

Everyone's body responds differently, and individual results will vary based on factors like your starting point, lifestyle, and goals. That said, most people begin to notice measurable changes in body composition - such as shifts in fat mass, muscle mass, or weight - within a few weeks of consistent tracking combined with healthy habits. BodyFit's 6-zone segmental analysis gives you a precise, ongoing picture of how your body is changing over time, so you can spot progress that a standard scale would miss. Note: BodyFit is not a medical device and this does not constitute medical advice.
The Withings app lets you generate and download a tailored health report PDF that you can share directly with your healthcare provider. You're always in control of your data - you can select a specific time frame of data to share with your healthcare provider, and you decide which third-party apps, if any, can access your information.

BodyFit is built with technology that goes far beyond a standard bathroom scale. It uses 8 electrodes and Multi-Frequency Bioimpedance Spectroscopy across 13 frequencies up to 800 kHz to deliver independent body composition readings for six body segments - your arms, legs, torso, and abdomen - measurements that have been validated at 99% correlation with DEXA scan results¹. It also tracks over 40 biomarkers, provides metabolic assessment data including Visceral Fat Index and Basal Metabolic Rate, and offers cardiovascular insights like Vascular Age and Pulse Wave Velocity. Most consumer scales measure total weight only. BodyFit gives you clinical-grade precision at home - which is what the price reflects.
