NZThe article explains the scientific process of weight loss, focusing on where the lost weight actually goes. It states that losing weight involves creating a calorie deficit, which triggers the body to burn stored fat. Fat is broken down into fatty acids through digestion and stored as triglycerides in fat cells. During weight loss, these triglycerides undergo lipolysis, breaking down into fatty acids that enter mitochondria for energy production via beta-oxidation. This process produces carbon dioxide and acetyl-CoA, with the carbon dioxide being exhaled. While some weight is lost as water through sweat, the majority is expelled as carbon dioxide through breathing. Researchers suggest approximately 84% of fat is exhaled as CO2 and 16% is excreted as water, though precise measurements remain challenging.
