The OP is about how much buoyancy is left after you empty your lungs. Approximately all of our normal buoyancy comes from the lungs.

Yes, that's what I'm saying - unless you are quite obese, your body fat will not be so huge a factor that it will cause you to float with your lungs empty. You might not sink quite as far but still.
