By definition, a calorie is the amount of energy required to raise the temperature of a gram of water by one degree centigrade.
So, drinking a litre of pleasantly cool water, say, 8 degrees centigrade will cost your body 28000 calories to raise to body temperature of 36 degrees centigrade.
Soon you'll be skinny like a catwalk model. That's the secret! Where's the error?
