To be fair BMI is based on Belgians from the 1850s with all the implications it has. Modern people are much taller (+15 cm for males) and eat a lot more protein.

So the line between normal and overweight is somewhat blurry. e.g. someone who is 6'3" and weighs 200 pounds is overweight. Which might or might not be the case (but you certainly don’t need to a body builder or invest a lot of time to maintain at least reasonably healthy 18-20% body fat ratio).
