I've heard this one before, several times. And this is what they claim (which, oddly, if you think about it makes sense):
When you drink really cold water, your body has to work a little harder to 'metabolize' it to bring it back down to normal body temperature. This is why they say to drink a glass of ice water [approx. 1/2 hour] before meals because your metabolism will already be in high gear from working to 'warm up' the ice cold water; therefore more of your calories from the meal will be burned up in the process.
Now, this is what they claim. Whether or not it's true or whether or not I believe it is something else entirely. Honestly, I've never really given it much thought.
