weight lossEver wondered where exactly fat goes when weight is lost? It seems to just disappear, but how is that possible?

The most common misconception amidst the health and fitness industry is that the fat is converted to heat or energy. A study by researchers at the University of New South Wales, Australia, looked at this process and found that is not the case. Physicist Ruben Meerman, the head author of the study, says that most of the lost mass is breathed out as carbon dioxide.

The study, which is published in the British Medical Journal shows that a 10 kg (22 lb.) requires 29 kg (64 lb.) of oxygen to be inhaled and that this process creates 28kg (62 lb.) of carbon-dioxide and 11kg (24 lb.) of water. If you ‘follow,’ so to speak, the atoms of the 22 pounds of fat loss, 19 of them are exhaled, while the remainder is excreted as fluid.

When the authors of the study announced their findings, one of the most common questions that they then received was: does breathing more mean I’ll experience increased fat loss? Unfortunately for those looking for an easy fat loss solution, the answer is no.

    Seems to me that the fat is still the fuel source for energy at the cellular level and the carbon dioxide that is exhaled is a result of cellular metabolism. it is important to note that CO2 is a waste or by product of cellular metabolism. As we excercise our body becomes acidic ( increase in co2 and hydrogen ions) and one way we balance this PH change is by blowing or breathing off the excess CO2. Which again is a byproduct of cellular metabolism that is being fuelled by the fat. Other fuels our bodies use are carbohydrates and proteins which also go through the same cellular process and have our bodies produce Carbon dioxide as a by product.

    Not a very good article or study in my opinion. The process is just not that simple as the article would have you believe.
