The primary way we get rid of excess weight is actually breathing. As we breath out, CO2 is produced. So when we burn more calories than we take in, your body gets rid of the excess carbon in the form of exhaling. Of course other methods of “elimination” in the rest room count too, but the main source of permanent weight loss is still breathing

Believe it or not your body primarily loses weight by breathing it out. The CO2 + water vapour breathed out is heavier than the O2 taken in. CO2 + water are by products of the respiration chemical reaction that occurs in your cells to provide energy.

You pee, poop, sweat, and breathe it out. That’s what happens to everything you consume that doesn’t get stored, and everything stored that you use up.

Usually, a chemical change is involved.

Fat is made of carbon, hydrogen and oxygen, in the same compound.

When we use that as fuel (because we have already spent everything we ate), we break down that compound into some energy, plus CO2 and H2O.

We mostly exhale that CO2. Water, some of it is exhaled, some may go down the drain.

From what others have written. I feel like the energy that were used by our body to perform the motions when we’re exercising is still considered energy use. Like. Is it not basically chemical energy turning into kinetic energy?

This is just a guess though. I’m not exactly a scientist myself lol.
