InBody sells the scale for the Ozempic era and refuses to pick a favorite drugmaker
US hospitals bought InBody's body-composition scanners at a 60%-plus clip in the first half of 2026, on one analyst's estimate, as obesity clinics add the muscle tracking the drugs demand. Founder Cha Ki-chul is declining exclusive pharma deals to stay the neutral instrument in every clinic.

One scanner, every drugmaker
The obesity drug boom needs something it never budgeted for: a machine that can tell fat from muscle. InBody founder Cha Ki-chul has been selling such machines for 30 years 1. In 1996 he visited one Wonju clinic about 20 times to close a single sale 1; now drugmakers approach him about cooperation, and he is holding off, because a tie-up with one would damage relationships with the others 1.
The muscle the drugs burn
Semaglutide takes off about 15% of body weight on average, tirzepatide about 20%, and some of what goes is lean mass, which is why clinicians pair the drugs with protein targets and resistance training 4. A bathroom scale cannot tell fat from muscle; the machine that can is the opportunity.
The demand base keeps widening. Gallup puts GLP-1 weight-loss use at 11% of US adults in 2026, up from 3% in 2024, and the Korean analyst note lands on the same 11% 25; the class took 14% of US drug spending last year 5. On InBody's own testimonial page, the weight-loss physician Dr. Adrienne Youdim says the scanner "made it possible for me to manage my clients at scale" 8.
Hospitals are now the engine
Korea Investment & Securities analyst Hong Ye-rim estimates InBody's US hospital sales rose more than 60% in the first half of 2026, after 28% growth last year, lifting hospitals from 37% to 44% of US revenue 2. Machines sit in about 2% of roughly 224,000 US medical facilities 23.
Margin tells the same story: the cost of building overseas direct sales squeezed operating margin from 26% down to 16%, and it recovered to 20% in Q2 2026, the first time in nine quarters 2. The brokerage forecasts 288.1 billion won of revenue this year, up 23.1%, and 58.6 billion won of operating profit, up 59.4% 2; Cha expects 280 billion to 300 billion won of sales, and 500 billion within four or five years 1.
One caveat: the 60% figure lives in a single analyst note; InBody has not disclosed hospital-sales growth itself.
GLP-1 use more than tripled, hospitals hit 44% of US revenue, margin recovered to 20%

Data
| Before | After | Change | |
|---|---|---|---|
| GLP-1 use, US adults, 2024 to 2026 | 3% | 11% | +266.7% |
| Hospital share of InBody US revenue, H1 2026 | 37% | 44% | +18.9% |
| InBody operating margin, trough to Q2 2026 | 16% | 20% | +25.0% |
The demand side has a leak
The boom feeding the scanner has a coverage problem. About 14% of US employers have dropped or plan to drop GLP-1 coverage in 2027, and the share of employers covering the drugs fell from 72% in 2025 to 60% in 2026 6. Wegovy lists at $1,349 a month 6.
What no source here shows is the per-scan bill: whether insurers or patients pay for repeated scans, and how often, is not disclosed. InBody hedges the other way regardless: in July it became the official measurement partner of HYROX, the fitness-racing circuit, its old home turf 7.
The re-rating hangs on 2% and a signature
Two readings decide the re-rating: installed machines against that 2% penetration line, and whether Cha signs with any drugmaker at all. Hospitals already generate more than a third of sales and are the fastest-growing segment 1. His 240 million accumulated measurements are worth most while every party still needs him 1. "I don't think InBody has reached its peak yet" 1.
