FAT burning lies in your lungs

The research conducted by a team at UNSW Science in Sydney calculated exactly what happens to our fat when we shed kilos, and revealed that doctor's leading theories are wrong - we don’t convert our missing mass into heat or energy, we breathe it out.

Their results, published in the British Medical Journal, reveal that 10 kg of fat turns into 8.4 kg of carbon dioxide, which is exhaled when we breathe, and 1.6 kg of water, which we then excrete through our urine, tears, sweat and other bodily fluids.

At the UNSW School of Biotechnology and Biomolecular Sciences,  the team started calculating the biomolecular reactions that result in weight loss. They put on weight when excess carbohydrates and proteins that we've eaten are converted into triglycerides (compounds made up of carbon, hydrogen and oxygen) and are then stored in lipid droplets inside fat cells. To lose weight, you need to break down those triglycerides to access their carbon.

The results showed that in order to completely breakdown 10kg of human fat, we need to inhale 29 kg of oxygen (and somewhere along the way, burn 94,000 calories). This reaction produces 28 kg of CO2 and 11 kg of water.

“Our calculations show that the lungs are the primary excretory organ for fat,” the team writes in the paper.

However, they couldn’t work out exactly what was happening to the fat cells in this reaction. After months of research, Brown discovered a formula from a paper published in 1949 that solved the problem - it showed that oxygen atoms are shared between the carbon and hydrogen in fat at a ratio of 2:1 (forming carbon dioxide and water)

This allowed them to come up with the final figure of 84 percent of a fat molecule’s atoms being exhaled as carbon dioxide, and the remaining 16 percent ending up as water.

But unfortunately this doesn’t mean that simply breathing deeply will help us lose weight - we still need to do the exercise to unlock the carbon and break down the fat in the first place.

"You can only breathe so many times a day; on a day of rest, you breathe around 12 times a minute so 17,280 times you'll breathe in a day and each one takes 10 milligrams of carbon with it, roughly," Meerman told ABC Science. "So there's your limit on how much you're going to lose in a day with no exercise."

Below is a video made a few months ago on how an athlete can use foods to boost their performance. Now when I write this article it strikes me on WHY ATHLETES tend to have the SIX PACKS faster than anybody else. Its in the lung.
