Right, im aware of how fat leaves the body - breaking down through osmosis and suchlike yada yada till eventually it makes its way out with your urine.

The thing i would like to know is just how long this process takes ie;how long from exercise to flush does it take, that is as long as you are drinking plenty of water.

Anybody got any ideas? (im looking at you steve:D
 
Your question is a tad hard to answer...
Though, to answer simply. Once a fatty acid molecule(for example) has been placed into the correct metabolic pathway, such as B-oxidation > CaCycle for the production of ATP. Whats left is Carbon dioxide and that is exported from the body through exhalation fairly soon after complete oxidation.

The urinal system is used as another means to help "carry" some left over molecules from lipolysis and so on. Obviously, you pee when you pee. So, can't quite give you an idea how long this would take.

Last but not least, given energy conversion isn't running at 100% efficiency. It would be safe to assume some "fat" is lost through the generation of body heat from this inefficiency in energy conversion.

So to answer your question directly, Overall, its fairly instant...

Yea, you're asking about a very complex process.
