It's true, in theory that cold water would have a "negative" calorie balance because you'd have to burn additional calories to maintain body temperature, but I remember in college a human biology professor had us calculate how much weight you could lose (in theory) just with this change. I don't remember the specific results, but it was something ridiculously low like 3-4 lb per year (assuming 1 gallon of ice water consumed per day).
He went on to further debunk, talking about ways in which the "real math" was probably even less (such as the reduction in body temperature, could increase hunger.... stuff like that).
I always knew it was ridiculously small, if even any effect, but shoot...even if it's half a pound every 5 years, I"ll take it!! Originally Posted by kaplods
