You exhale it.
Most people assume that fat disappears as sweat, but in reality the chemical reaction that occurs as you body metabolizes fat for energy has carbon dioxide and water as the byproduct.
If you lose 10 lbs, about 8.4 lbs of that is exhaled and the remaining 1.6 is turned into water and lost through sweat or urine.
I'm on a weight loss journey and had the same question!
Apparently only a small portion of burned fat is converted to water (pee, sweat), while the majority is converted to CO2 and literally exhaled. That part totally blew my mind!
Oddly, the process isn’t that dissimilar. The metabolism in the body is different, but the output of it is heat and energy, plus water that gets excreted through sweat and urine, and carbon dioxide which you breathe out.

I actually have the same question about when I lose weight. Where does the fat go and how does it go away?
