Emmitt Smith was around 5’7” and 220 lbs. when he played. BMI is BS.
muscle is much denser than fat, so for athletes the BMI is not accurate at all. But lets be honest here, the people that are pushing this are not athletes, they are morbidly obese with no muscle mass, but simply want to not be told they are what they are.
Its a pofential indicator. By itself it doesn’t provide enough context. Its just a heith to weight ratio so it really can be a useless number for certain body types or people with chronic conditions.
Ie it would say a sick person who’s underweight is healthier than an athlete that says hes obese.
It would say a person who not overweight but doesn’t exercise is healthier than a person who exercises but muscle pushes them to a “overweight” bmi number.
It would say a fat person who doesnt exercise could be equal in hezlth to a fat person who does exercise.
It could say a person with a chronic illness could be healthier that a person who is called fat by their bmi number but who exercises.
That number alone doesn’t provide a full picture and often provides an inaccurate picture. More context is required.
