A 6 feet bodybuilder could pass 100kg with flying colors and no body fat to speak about.

Is BMI really the same for males/females? I always assumed that what is obese/overweight for a 5'9 woman would be different than a 5'9 man.

Bmi is mostly bullshit. Much better indicators for overall health is the amount of belly fat and the fat around the internals organs. Having a lot of fat on the butt/thighs is much less damning than lets say fatty lever.

Thanks. I am curious about "lever." Was that a typo or a english-locale dependent noun? I am not trying to be a typo jerk, I produce them constantly, I am just curious what the word is.

Its liver ...

Thanks for following up. I dont know why liver did not occur to me and I stared at the keyboard before replying.

There have been suggestions that slight differences should be allowed depending on one's race and age, too:

good work. Keep at it and branch out. Try and ignore the negative comments here. The IT industry is full of big egos.
