Example of what people mean when they throw doubt on BMI scale.
Daniel Ryan Cormier
Olympic wrestler & UFC Champion
Born: March 20, 1979 (age 40 years), Lafayette, LA
Height: 5′ 11″
Weight: 235 lbs
Body mass index (BMI)
A measure of body fat in adults
32.8 = Obese BMI
(I'm a little taller and about 10 pounds lighter than dude above ...and I would still be considered "Obese")
Now obviously most people are not Olympic caliber athletes but you have to define normal by who's standard and body type?
Cause Obese doesn't automatically mean the following either.
The important thing also is lets say a subset of "obese" people have health problems. You have little way to know what type of "obese" a person is just by BMI alone. It reminds me of when people go to Impoverished African Americans and try to use whatever data/metric they pull from that analysis as a means to characterize all African Americans even though overwhelming majority of African Americans are not impoverished.
I.E. you don't know what fitness level a person of a given BMI falls in just like you don't know what income level a person of a given racial group falls in. You can't take the worst case scenario and use that to go on a triad without being questioned and looked at sideways.
With that BMI issue out the way and addressed I will say the two major health issues for African Americans from my perspective is....
- Lack of sun exposure to convert cholesterol into vitamin d (cholesterol build up and vitamin d deficiency are rampant and cause a wide array of cascading issues)
- There is nothing embedded in the culture that pushes physical activity after say ...high school.
As a kid you play street ball, football, etc. as an adult those things fall off and people have to make a conscious decision to engage in activity; where when young going outside in the sun and playing sports was simply part of childhood culture. And that's even though that kid spent the same 9-5 sitting on their ass in school that adults spent on their ass at work.
This abandoning of physical activity "cause you grown" or whatever, is often magnified for women.
