Where does the fat go that you lost?

Tami113

ok this may be disgusting so forgive me in advance. When you lose weight where does it go? Do you poop it out? Do you sweat it out? This may sound dumb but i would imagine that someone losing weight does not poo out 50 lbs 100 lbs of stuff. The theory is that you can neither create nor destroy matter so every week that i have been losing 2 lbs where is it going? I don't "go" any more than usual and yet i have lost 9 lbs. 9lbs isn't a lot compared to some of you but in mass, as a physical, tangible thing, 10 lbs is alot of stuff.

It is being chemically changed into energy. It's burned for fuel. You've seen wood broken down by fire into ashes? Well, the heat generated is the energy. The ashes are the byproduct. The byproducts of fat metabolism are metabolites that are carried away through the kidneys and expelled in urine.

And then you poo and pee it out. Let me clarify..then you poo and pee what's left out. I think that is where the water comes into play.

I couldn't have explained it better myself. You are so right about the fat is burned down as fuel and processed through your liver and kidneys and then yes, pooped and urinated out.

Interesting. Never thought of using wood burning as a metaphor but it fits. But in both wood burning and fat loss it still boggles me that the mass before and after are so different. The "ashes" being expelled weighs less than the "wood" being burned. So all of it can't be pooped and peed out? As a science major you would think i would understand but it still confuses me.

Life confuses me, but I still do it.

BlytheW, I love that saying! Did you make it up or what?

Which? What? Thank you.

In wood burning, the ashes left weigh less than the wood that burned; but if you could capture all the smoke from the fire and weigh all the tiny particulates and steam and other components of the smoke, their mass would add up to the difference between the mass of the wood and the mass of the ashes. Combustion scientists have actually done this experiment, and the mass really does balance out.

Okay, I know a lot less about the physiology of weight loss than I know about combustion science, and I just told you most of what I know about combustion science. But don't think I'm going to let that stop me.

Let's say you lost a little over 2 pounds this week, and that exactly 2 pounds of the fat you lost was water, was converted to water in the fat-burning process, or became dissolved in water. Forgive me for going all math-geek on you, but:

Water weighs 8.33 lbs per gallon, so 2 lbs/(8.33 lbs.gal) = 0.24 gal

There are 128 ounces in a gallon, so (0.24 gal)*(128 oz/gal) = 31 oz
(Doncha just love the English system? :huh: )

And seven days in a week 31 oz/week/(7 days/week) = 4.3 oz

Now, if you're drinking eight 8-oz glasses of water a day, you had better be peeing out at least 64 ozs per day. 4.3 oz/64 oz = 0.067 = approx 7%.

Are you really going to notice a 7% increase in the volume of your pee? IDK, but I'd guess that normal non-fat-losing pee volume may vary more than that from day to day anyway.

As long as I'm losing the fat and weight I'm happy! haha! although it is an interesting question never really thought about it either.

IrishMinx32

OH WOW!!! Thats all I can say after that response.

BlueInkDot

aaaaaaaaah That was so interesting! There are geeks here! Awesome! XD

I guess the lesson here is you can't lose weight unless you drink all sorts of water to facilitate urination so you can actually expel it!

SCIENTIFIC PROOF YOU GOTTA DRINK UR WATER Y'ALL.. I love it.

We also express fat as oils in our skin, hair etc... we lose moisture through expiration and perspiration... small amounts but still important to remember.

We need fats for brain function (depression has been linked to reduction in fat cells in the brain - sorry don't have a reference for that) and to absorb certain vital vitamins... e.g. vit k is fat soluble and aids clotting mechanism.

So as well as converting and burning the fat the body uses fat in these ways... and eliminating those byproducts

I've also been told that fat stores various toxins, heavy metals and hormones etc in minute quantities but it sometimes accounts for mood changes and feeling under the weather sometimes and again why drinking the water, to flush those things out, is so important.

When you lose weight it magically appears on my bum. My bum is like a lost fat magnet.
Nothing to do with the cupcakes I may eat.

You are so cool! I love people who understand what is really going on! Brains are so SEXY! OMG!

So, wait, this is why I'm peeing more than I am drinking?

Awesome information everyone! Even had a LOL moment.
