Where Does Fat Go When You Lose Weight?
Andrew Brown from the University of New South Wales and Australian TV personality (slash former physicist) Ruben Meerman say that when you lose weight, you emit your fat. “There is surprising ignorance and confusion about the metabolic process of weight loss,” Brown says in a news release. “The correct answer is that most of the mass is breathed out as carbon dioxide,” Meerman adds. “It goes into thin air.” Extra carbs and proteins are turned into triglycerides and are then put in the lipid droplets of fat cells.
When you lose weight, you have to metabolize the triglycerides. This unlocks the carbon that’s in your fat cells. Losing 10 kl of fat requires the consumption of 29 kl of oxygen. This produces 28 kl of carbon dioxide and 11 kl of water. The pair then calculated the proportion of the fat that leaves as the carbon dioxide and as water when we lose weight. They discovered that 8.4 of those kl let out as carbon dioxide by tracing the pathway of the atoms leaving. Our lungs are the main excretory organ weight loss. The rest of the kl become water then it is turned in to urine, feces, sweat, breath, tears, and other body fluids.
