Fun Fact

The BMI formula is over 190 years old and was never intended for individual diagnosis, yet it remains one of the most widely used population-level health indicators worldwide.

Body Mass Index was developed in the 1830s by Belgian mathematician Adolphe Quetelet. Long before digital health tools existed, it was designed as a simple statistical measure to understand human body patterns across populations.
