Question:
Where do all those pounds of fat go?
Hi! I am just over 8 months post op and have lost 95 pounds. I was just wondering, where did all the fat go? That's a lot of fat!! How does the body process it and how does it leave the body? Just curious. THANKS!! — Jennifer H. (posted on March 6, 2004)

Much gets burned for fuel. The waste products account for going to the
bathroom even when eating so little.

My husband took it off my hands. Poor guy has gained like 40 pounds since
my surgery last year. But yes, it is eliminated in the "potty".
Also, another good reason for drinking so much water to help flush out your
system.
Best of luck to you and congratulations on your weightloss.

It is gross, but you lose the fat from bowel movements, peeing, sweat,
blowing your nose, not sure on that one, but that gives you a idea. The
previous poster is right, drink alot of water to flush out your system.
BTW, good job on losing the 95 lbs.

it is not as simple as pooing it out. simpplified explanation from my
collge anatomy and physiology book, fat that is not immediately used as
energy is stored in adipose tissue (fat depots) . before the fat molecules
can be utilized as energy it mmust be released from the fat depots and
split into glycerol and fatty acids. the glycerol and fatty acids are
catabolized separately. glycerol through several chemical reactions in the
body is converted to glucose,the chief source of energy in cells. the
glucose is then broken down thru glycolysis, Kreb cycle and electron
transport chain. fatty acids go thru a series of complicated reactions
eventually breaking down into ATP which enters the Kreb Cycle (Rmember
that from High school biology?)to the best of my understanding a simplified
explanation is that the energy from the fat is expended as heat energy ,
and, water and CO2 are produced.
the fat you are seeing in the toilet is from the fat in the meal you
recently ingested and is passing thru your intestinal tract with out having
been absorbed or stored in your adipose tissue due to the malabsorption
factor of the surgery. I would suggest getting a high school or college
biology book and reviewing so you can get actual facts rather than made up
theories.

Wow, Willow! You sound like my anatomy and physiology professor! You
actually remember all that????? Geesh. I remembered it was converted to
fatty acids and eventually glucose and burned as fuel ---much simplified
from your correct explaination *G* I'm impressed, girl! <br>
Folks, Willow is right. Any fat you see in your stool is from food
recently ingested, not burned fat. Remember, any food we eat that is not
used for fuel is stored after it is converted to fat. To get rid of fat,
we have to break it back down and use it up. There is no way for it to get
back into our digestive system as fatty stool!

I must confess... I got out my text book, (being a pack rat has its uses)
and looked it up and condensed 10+ pages into a paragraph. I only
remembered very loosely a little of it til I reviewed.

The easiest way to explain it is actually quite simple when you think about
it (though it still may not be totally understandable). Losing weight is
like gassing up a car. You put the gas in and it disappears, right? Where
does it go? Heck if I know, but it is used by the car for energy, and thus
is broken down and disappears and you have to refuel the car because the
gas is gone. Losing weight is the same thing. Food is basically one
thing...ENERGY for the body to run on (for the heart to pump, the lungs to
breath, the veins and arteries to circulate, the brain to work, the toes to
wiggle....and everything else in between). When you are dieting, your body
still needs a certain amount to run on and if you aren't taking it in in
food, then the body uses the stored fat. Just like gasoline, it is used
and broken down by the body and disappears. Hope this helps.
