Weight / Fat loss

And as for Bothwell's example, I'd guess she forgot to count the 5 pints of lager and/or the bottle of wine that accompanied the gammon :), or the ice cream, we know she loves ice cream too. And I'd wager by the time that gammon had worked its way through it was converted into the amount of pooh someone on D-wing planning a dirty protest would dream of producing. Sorry that is clearly too much pooh talk, draw your own collisions >>>>>>>

This is all bollocks apart from maybe the poo bit which I can't remember as I blocked most of the Gammon Incident from my memory. The magic ingredient was the 8.8 grams of salt that the gammon contained which led to massive water retention.

It's easy to think of the body as a rubber bag, where you put materials in and you get materials out. The bit that's being forgotten here is that the precise materials that you put into the rubber bag interact with each other and the bag itself so you get different amounts of materials out depending on what you put in. (By "out" I don't just mean "waste products", I also mean "heat", "energy", "fat reserves", "glycogen reserves" etc etc).

If you ate two mars bars and I ate the equivalent weight in lettuce leaves, who do you think would store more calories in the form of fat?
