Okay, it’s not as simple as the title makes it appear to be. However, How Stuff Works gives some scientific proof to answer the question, “Does drinking ice water burn calories?” I’ll cut right to the good stuff:
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.
