This is the stupidest thing ive heard imy life, i'm an excraft butcher, what the fuck do you think your skin is? Fat you dumb shit, to be 0%. Fuck me pure fatless beef with no skin is around 1-2% body fat, thats the leanest muscle possible, and your trying to say a human body with no trimming of the muscle fibres and skin still attached is even close to this.
If you took even the leanest body builder and did an accuate break down of his fat levels slaughter house style he'd be over 3% easily
