your body has to use energy to raise the temprature of the ice cold waterThere's no such thing as negative calorie food/drinks, but I know what you mean
And it was just the thought of someone eating a plate of ice that made me laugh
1pint of 0 degree water = -17.5 calories
probably more than those suposed fat burners actualy do which was the point i was making
if your drinking water anyway you might aswell drink ice cold water
