Ask a stupid question: can you lose weight drinking cold water?

[martin_wisse]

So a co-worker remarked that drinking cold water made you lose weight, as you burned calories heating it up to body temperature when you drink it. Myself, I said I couldn't see it, as just the normal loss of heat in your mouth and elsewhere will heat it up anyway. Does anybody got any idea either way?

not that I'm that desparate to lose weight; I got the body of a Greek god, if that god is Dionysus.
