Where does the fat we lose when losing weight go?
As you know, if you want to lose weight, you have to stop eating after 6:00 p.m. well, jokes aside! After all, everyone knows that it is a question of caloric intake and activity. But one thing is not a joke, on the contrary, it is a pure fact. If we try to lose weight, we lose fat. But have you ever wondered where all the fat we lose goes? Whether you have thought about it or it has only come to your mind now, read an interesting study that dealt with exactly how it is with this fat and where it travels.
The UNSW Science in Sydney team found out what happens to fat when we lose some pounds. It turned out that the theories of doctors were wrong. We cannot convert lost matter into heat or energy, we exhale it. The results, published in the British Medical Journal, show that 10 kg of fat is converted into 8.4 kg of carbon dioxide, which we exhale when we breathe, and 1.6 kg of water, which we excrete through urine, tears, then and other body fluids. "The correct answer is that we exhale most of the matter as carbon dioxide. It just goes up in the air, ”said research author R. Meerman.
He first became interested in biochemistry in weight loss after losing 15 kg and asking doctors where this lost weight was going, they couldn't tell him. After a survey of 150 doctors, dietitians and personal trainers, he found that more than half of them thought that fat had been converted into heat or energy. But as a physicist, Meerman knew it would be against the law of conservation of matter. To find out exactly how it all works, he worked with A. Brown, head of the UNSW School of Biomolecular Sciences, and began counting on the biomolecular reactions that led to weight loss. Excess carbohydrates, proteins are converted to triglycerides (compounds made from carbon, hydrogen and oxygen) and then stored in lipid droplets inside fat cells. If they lose weight, these triglycerides need to be broken down to gain access to carbon. The results showed that with a complete decomposition of 10 kg of human fat, we need to inhale 29 kg of oxygen. 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," they say.
However, they could not figure out exactly what was happening to the fat cells in this reaction. After months of research, they discovered a formula published in a 1949 study that solved their problem - they found that oxygen atoms are shared between carbon and hydrogen in fat in a ratio of 2: 1 (forming carbon dioxide and water). This allowed them to come up with the final sum that 84 percent of the fat molecules are excreted as carbon dioxide and the remaining 16 percent will end up as water.
Unfortunately, this does not mean that we take several deep breaths and this will help us lose extra pounds. It is necessary to exercise, due to the reactions of carbon and the breakdown of fats.
“You can breathe a certain number of times during the day. During the days we rest, we breathe about 12 times a minute, so 17280 times a day, and each one takes 10 milligrams of carbon. That means you have a limit that says how much you will lose weight in one day without exercise, ”says Meerman.
The funny thing about it all is that according to the following video, we would not only lose fat when we breathe, but if we were a closed system, we would actually become trees. (I'm great!). In any case, a very interesting topic that we wanted to share with you.
