The triglycerides release fat as carbon dioxide and water atoms during fat metabolism or oxidation. In other words, fat leaves the body as carbon dioxide when you exhale. The fat which becomes water mixes into your circulation until it's lost as urine, tears, sweat and other bodily fluids.
Research shows that 84% of fat loss is exhaled as carbon dioxide. The remaining 16% of fat is excreted as water. During the conversion of energy, carbon dioxide, and water are byproducts of waste. They are excreted via urine, perspiration, and exhalation.
Mostly, losing weight is an internal process. You will first lose hard fat that surrounds your organs like liver, kidneys and then you will start to lose soft fat like waistline and thigh fat. The fat loss from around the organs makes you leaner and stronger.
