When we do exercise to burn fat, where does the fat go to, I know it is made into energy but I don’t understand how it just disappears from our body.
In: 8
Short answer: We breathe it out.
Most of the fat that we burn gets converted to CO2, which we exhale. There are some really cool articles on that very subject here on reddit, but that’s about the long and short of it.
The calorie burning process results in energy + heat + carbon dioxide + water. So we mostly breathe it out, then we release some heat and water.

CO2 and water, and useful energy. All your metabolic processes generate CO2 and water. Water is excreted mostly (some evaporates or is lost though breathing) and CO2 is picked up by the red blood cells, carried to lungs and exhaled.
to keep you alive it takes energy, when you move you ise more energy, exercise takes a lot of energy. that’s why when you go to sleep yiu check your weight and the next morning you loose like 1kg
CO2 and water, the products of combustion. The CO2 gets exhaled and the water is both lost from breathing it out and from urination.
Same this that happens to all other hydrocarbon fuel (oil, alcohol, gas, fat) during oxidation (burning).
hydrocarbon (fat) + O2 -> CO2 + H2O + energy
You breathe and pee it out.
You have the right answer already, which is that your breath is lighter breathing in, than breathing out. But an interesting twist on this is that plants do the opposite. They breathe “in”, their metabolism pulls the carbon out and uses it to grow, and then breathe “out” air with less carbon in it.
think of a log burning in a fire place.
an hour of heat and light.
and that heavy solid chunk of wood is now a half cup of dust.
proteins are converted into tools, sugars are broken into smaller units.
what’s left is filtered out by your kidney, liver
