Ask HN: Why no one has built Body Fat Tester Machine Startup?

The existing methods seem unreliable and not consistent. Why no startup has worked in this field?

Search for DEXA/DXA scan facilities (low dose X-ray exposure). If you're referring to at home testing, devices exist that use electrical current to provide rough measurements (think body fat measurement capability on weight scales), but accuracy is inherently limited. An MRI is the only non radiation high accuracy measurement technique at this time.

Perhaps an opportunity to sell spare MRI time paired with ML for providing this product?
