Just looking at this got me thinking. The average guy carries around 50% more LBM than the average girl.
An average woman might be 80 lbs of LBM, at 120 lbs at 33% bf.
An average man might then be 180 at 33% and thus carry 120 lbs of LBM.
A 220 lb lifter at 18% carries around 180 lbs of LBM.
So he is as different to any average skinnyfat guy as the guy is to a skinnyfat girl.
The next level up would have to be like a 330 lb NFL players at 20% who carries around 270 lbs of LBM. So he would be to your 200 lb lifter as an average guy is to an average girl.
