I will also add, that it's impossible to be 220 lbs and 3% unless you are using drugs, which takes into account most professional bodybuilders who are not in natural competition. Furthermore, modern day methods of measuring bodyfat all carry a margin of error. So the chances of an individual saying they are 3% when they are in fact 5-6% are quite high. So truly hitting 3% is generally reserved for hardcore competitors with more than one trick up their sleeves. Anyone who has actually attempted to hit single digit bodyfat will tell you that it is a very, very difficult feat, as your hormones go south and your body fights you tooth and nail. I specifically wanted to know if it was technically possible to inflate muscle mass enough to achieve 2% body fat without death. I read the articles you posted, and I did not find anything to lead me to believe that essential fat, in lbs, increases with body weight. An anorexic guy (A) at 120 lbs who has an obese identical twin (B) at 300lbs. A has an essential body fat percentage of 5% and B has an essential body fat percentage of 2%. They both have essential body fat of 6 lbs, because they have identical insides. Makes sense to me. I didn't ask if you thought it was easy.
