Where does fat go?

LeonaLunaLioness

Does it melt into your sweat? And if it does would it make sense to get the sweat off you asap so it doesn't absorb back into your body?


Does it pass into your waste to leave your body in the form of poop or pee?

Or does it just magically just disappear?

I mean if you think about the whole scientific thing "Matter cannot be created or destroyed," then where does the fat go?

I could probably google the answer but idk, it's just a thought that might be nice to wrap your brain around.

I'm pretty sure its exhaled, technically. Adipose cells don't really disappear, they just get smaller.

Around 84% exhaled as carbon dioxide, the rest leaves as water (urine or sweat, mostly, but some water also exhaled as moisture, or is lost via other bodily fluids).

The "burning" idea is pretty literal: It leaves as CO2, and H2O.

Fat is converted to energy and used. Which leaves waste products exiting through the exhaust just like when your car burns petrol. Only our exhausts are our lungs, and to a lesser extend our kidneys and sweat glands.

Burning is candle is a decent analogy.

When you burn the candle you get energy (heat & light in the case of the candle) and the solid candle is converted to gas.

When we lose weight, where does it go?

"If you lose 10kg of fat, precisely 8.4kg comes out through your lungs and the remaining 1.6kg turns into water. In other words, nearly all the weight we lose is exhaled."

Fat doesn't "melt" as so many visuals of lard melting in a pan are seen by many at one time or another. Chemical reaction converts it to energy for the body to use and it's mostly exhaled.

Anyone else been around long enough for the fat in your pee answer?

Someone believed you literally peed it out and it looked like chicken fat. While there were some medical concerns expressed if they were actually seeing this, the follow up comments where entertaining.

Wow!

I knew that the fat stores in our body were converted to energy to use, but I've never thought about it further than that. This is very helpful, and also totally crazy.

Bodies are amazing.

I don’t care where the fat goes as long as it doesn’t come back!

Doesn't melt. It is used as fuel, and like your car, when fuel is used it creates emissions from your tail pipe. Most of it is exhaled in the form of CO2. Some is expelled as water. Your actual fat cells remain, but they're like deflated balloons.
