Weight loss facts What actually happens to the fat that you burn?

When it comes to exercise and losing weight, one often speaks of fat burning. But hardly anyone knows what happens to the burned fat in the body, after all, the love handles don’t go up in flames while jogging. It is true that 80 percent of what we work out dissolves in the air – as carbon dioxide through our breath.

The chemistry of burning fat

Researchers at the University of New South Wales discovered what actually happens when the human body breaks down fat. The process is actually similar to that of an incineration, in which substances are converted. Our fat molecules are made up of oxygen (O2) and carbon (C). When we move around and “burn fat”, they combine to form carbon dioxide (CO2). The blood transports the CO2 into the lungs and from there into the air. And so 84 percent of the burned fat evaporates in the air when you exhale. The rest is water, which we also excrete with the air we breathe, but also with sweat, urine and tears.

Your new turbo metabolism against fat deposits

29 kg of oxygen for 10 kg of fat burning

Although the basic processes of lipid metabolism were already known, no one had ever thought of calculating the amount of oxygen involved in the metabolism. The authors of the study call the process of excreting fat as CO2 via the air we breathe, oxidation. And for this we need a lot of oxygen from the air we breathe. To burn ten kilograms of fat, our lungs have to absorb 29 kilograms of oxygen. The result of this metabolic process is 28 kilograms of CO2 and eleven kilograms of water.

Get rid of love handles permanently

But what can these numbers tell us about losing weight? A person weighing 70 kilograms inhales and exhales around 17,280 times a day and loses around 200 grams of fat in the process. An additional 40 grams of fat is burned after an hour of running. If you don’t want to feed yourself the calories again, you should be careful with sweet and fatty foods, the experts advise. An example: a muffin weighing 100 grams already covers 20 percent of the daily energy requirement of an average person. In order to lose weight in the long term, only one thing helps – exercise more and eat less.
