Does drinking cold burn more calories than warm water?

yes, you burn calories to warm the water up to body temperature.

Let's figure out exactly what you're burning when you drink a 16-ounce (0.5 liter) glass of ice water:

* The temperature of ice water can be estimated at zero degrees Celsius.
* Body temperature can be estimated at 37 degrees Celsius.
* It takes 1 calorie to raise 1 gram of water 1 degree Celsius.
* There are 473.18 grams in 16 fluid ounces of water.

So in the case of a 16-ounce glass of ice water, your body must raise the temperature of 473.18 grams of water from zero to 37 degrees C. In doing so, your body burns 17,508 calories. But that's calories with a little "c." Your body only burns 17.5 Calories, and in the grand scheme of a 2,000-Calorie diet, that 17.5 isn't very significant.

But let's say you adhere to the "eight 8-ounce glasses of water a day" nutritional recommendation. In 64 ounces of water, there are 1,892.72 grams. So to warm up all that water in the course of a day, your body burns 70,030 calories, or 70 Calories. And over time, that 70 Calories a day adds up. So, while you definitely shouldn't depend on ice water consumption to replace exercise or a healthy diet, drinking cold water instead of warm water does, in fact, burn some extra Calories!

Answer 2

Agreed.....nope..

Answer 3

the theory is that if you drink cold water (perhaps preferably ice cold) your metabolism speeds up in order to keep you warm. That's what they say anyway, you might want to look it up:)

Answer 4

It does, hence the old joke of the scotch diet, but it's a trivial difference.
If you don't know about the scotch diet, here it is:
Every book with Calorie counts shows a drink has about 100 Calories. Simple physics will tell you that a scotch on the rocks, at 0 degrees Celsius, will have to be heated to 37 degrees (body temperature) when you drink it, so if you drink 50 ml, you'll use 1850 calories just heating it up to body temperature, the definition of a calorie being the heat it takes to warm one ml by one degree. So you're going to lose 1750 calories every time you drink a scotch on the rocks.
The joke, of course, is that a calorie in physics is a thousandth of a kilocalorie, which is also known as a Calorie (with a capital C), but most writers and editors are sloppy about the difference, if they're aware of the difference at all.
