How Are Fats Burned in the Body Excreted?
When losing weight, most people wonder through which pathways and how the fats burned in the body are excreted. Does fat turn into heat? The conversion of fat into heat is not possible as it contradicts the law of conservation of mass. Matter can only be converted into energy as a result of fusion reactions. When your energy intake decreases, your body uses as much fat from your fat stores as it needs to meet the energy deficit. This used fat is excreted from the body as a result of metabolic processes. Fat from the food consumed is stored in the body in adipocyte cells in the form of triglycerides. Triglycerides are composed of three types of atoms: carbon, hydrogen, and oxygen. When triglycerides break down, about 20% of the molecular part turns into water, and the rest turns into carbon dioxide. While water is excreted from the skin as sweat and tears, it is excreted from the body through the urinary system. As carbon dioxide, it is expelled from the lungs through breathing. According to observations by researchers, to lose 10 kg of fat, 8.4 kg is converted into carbon dioxide and expelled from the lungs, while the remaining 1.6 kg is eliminated through bodily fluids. It is known that the lungs are the primary excretory organ for weight loss, with fat being oxidized and expelled as water through feces, urine, breath, and other bodily fluids. For an adult individual to breathe in and out a total of 18,000 times a day means expelling at least 2,000 grams of carbon dioxide. This corresponds to almost one-third of weight loss.

The Contribution of Exercise to the Excretion of Fats from the Body
A one-hour moderate-paced run or cycling exercise, instead of resting, results in the excretion of more carbon atoms from the body. Therefore, to achieve your weight loss goal, you need to create a balance between what you eat and what you burn, and you need to incorporate regular exercise into your life. Since fats burn slowly, you need to adjust the intensity of your exercise accordingly. The exercise must be sustained for 15-20 minutes without interruption for fat burning to begin.
Fats That Cannot Return to the Digestive System
Fats, muscles, and similar substances stored in our body and used outside the digestive system cannot return to the digestive system. The fats you burn are excreted from the body as carbon dioxide and water. In this regard, the main organ responsible for the excretion of burned fats from the body is the lungs.
