It's long been known that human fat cells are composed of carbon, hydrogen, and oxygen atoms. What's just been discovered by Australian scientists is that when we "burn" fat, almost all the broken-down fat molecules are exhaled through the lungs as carbon dioxide.

The research team, led by Ruben Meerman and Andrew Brown of the University of New South Wales, discovered that when 1kg (2.2lb) of fat is fully oxidized ("burnt"), 0.84kg (1.9lb) departs via the lungs as carbon dioxide. The remaining 0.16kg (0.3lb) becomes water which may be excreted in the urine, feces, sweat, breath, or tears.

The analysis shows that the inhaled oxygen required for this metabolic process weighs nearly three times more than the fat being lost.
