I drink 1.5 gallons of ice cold water per day approx. Numerous studies show that if you drink very cold water versus warmer water you burn more calories over time...can't remember the reason maybe lowering core body temp for a short time and the body reacts??

Uh, no, its a lot more simple than that, and can be illustrated with a question: has your urine ever been cold? I'm betting that the answer is "no" and that's because the body brings all food and drink you consume to body temperature. 1 1/2 gallons of very cold water would have to be heated up from maybe 40 degrees to 98.6 - and that takes a lot of energy. THAT is why you burn more calories over time.

By my calculation, raising 1.5 gallons of water 60 degrees F uses about 190 Calories.

That's not huge, but I suppose over time it would add up--provided you did not change the amount you eat to compensate.

Anybody want to check my arithmetic?

Conversion factors:

1 Calorie = 1000 calories
1 degree C = 1.8 degrees F
1 gallon (water) = 8.33 lb
1 lb = 454 gm
