I had a DEXAscan (not a medical one - those just tell you your bone density - this was one that also gives you your body composition. You can get them at commercial places like DEXAFit, or some universities have them in sports labs for their athletes - and sometimes the public can get them there for a decent price). I weighed 146 lbs at the time and thought I had a good 15 or so lbs to go. The technician said after the scan, "no - you're done losing". She said my body fat was 22%, which is considered lean for a female. I about flipped. All that "fat" was actually loose skin. So yea - I get it!
