Have you ever thought about where the fat goes when we lose weight? What happens to those lost fat cells?
The answer is: You breathe it out!
Of course, it is not about breathing out fatty air. When your body breaks down (burns) fat, a lot of carbon dioxide is generated.
When we lose weight, the body uses the stored fat. During this process, the fat is broken up into fatty acids that the body can use for various purposes. While the fatty acids are broken up, not only energy is generated, but also a lot of carbon-dioxide and a little water.
Triglycerides are comprised of three types of atoms: carbon, hydrogen and oxygen. Triglyceride molecules can be broken down only by unlocking these atoms, through a process known as oxidation.
I have found a British research in which they calculated how many breath ins and outs we need for this process.
To burn 10 kg fat, you need to breathe in about 29 kg of oxygen, and about 28 kg carbon-dioxide is generated. Also, about 11 liters of water is produced as well, that leaves your body with sweating, urinating, etc.
But this does not mean if you start breathing right now like mad, you will burn fat. The process cannot be started contrariwise. But if you start running right know, the CO2 you breathe out will be the result of the fat burning processes.
