I’ve heard you literally poo and wee it out
In: Biology
A lot of if you will excrete, yes, but that’s mostly excess you get through food. What you have in the fat stores on your body gets broken down into calories when you consume a caloric deficit, then used for energy to feed your organs, brain, muscles etc. The excess from that is also excreted out, like all other nutrients.
This TED talk explains it in detail. Math is fun!
You breathe it out as co2.
Co2 and water is the end product of cellular breakdown for energy.
Sort of. Fat is basically just a chain of carbon, hydrogen and oxygen atoms. When you break it down for energy, these compounds break down. Some of the carbon does leave your body as waste. Some forms CO2 which you exhale. Some forms water which you either sweat, death or pee out. The short answer is it ceases to look like fat and it leaves your body in different ways. Imagine a log of wood burning. Some of it turns to ash. Most of it disappears into the atmosphere
Most of it is breathed out. Most of your “material” is carbon. Carbon is breathed out in the form of co2
