When is a pound lost and where does it go?

bumping for laughs later.

you're all wrong. you fart it out and it goes into space. that's how new planets are formed.

I haven't read this whole post yet, but from what I have read some of the answers are ridiculous. There's a TED talk on this very subject. The man in the TED talk claims to have spent a lot of time researching this very question. He says that fat is broken down into H2O and CO2. H2O may be expelled through sweating or urine and CO2 is a bi-product of breathing. I'm not an expert but it makes sense to me. Most people tend to breathe heavier and sweat more when they engage in physical activity, and many people who engage in physical activity are either trying to lose weight or maintain their current weight.

So when you lose weight do you eventually have fewer fat cells, or do you have the same number of cells but smaller in size?

well you can stay at maintainance at burn 500 cals a day n you will lose a pound every week.
2nd ques when you are burning fat look for when thing when you go to toilet to pee you will notice something white in your pee is like chicken fat thats how some of your fat comes out n some as a sweat. because when i did a diet few years back when the white thing came in pee i got scared that its something serious but found out its nothing just fat so a doctor knows best.

Honey, if this were me I would be afraid, on SO many levels. Your doctor sucks.


Thanks for the laughs, I got my ab workout for today!

I'm a bit scared to answer this with so many science experts hanging around on this thread but here goes. It is my understanding that you always have the same number of fat cells, but when you lose weight they shrink. The only way to lose fat cells is to have them removed surgically.

I found mine under the bed where the cat hid it.

This Made me fart laugh when I read it LOL!

Don't be scared! The good news is that more recent studies have found that you actually CAN lose fat cells... but it takes years of maintaining a lower weight before these cells eventually go away.

Also, so glad someone bumped this. I had forgotten all about that classic MFPism on page 1.

There's is no fat breath. You're not exhaling fat, you're exhaling carbon dioxide. You're always exhaling carbon dioxide.

The 3500 calorie thing .. is not really truth.

Here is the real article from a recognized .. medical journal.

By re this thread .. it is converted to carbon dioxide and your body releases it.

Bumpety Bump

I think every pound you lost in December was found by my thighs.

Lmao!!

I went from tired and deflated on this couch, not feeling well, to a laughing hyena.

Best. post. ever!
