For anyone trying to lose weight, this question is an exciting one! Does drinking cold liquids burn more calories than drinking warm liquids?  The answer is a big resounding YES.  If you want to know if drinking cold beverages can help you lose weight the answer is also a YES, assuming the drink doesn’t contain calories, such as water.

There are two types of calories, (small “c” or gram calorie) calories  and (Big “C” or kilogram) Calories . The (Big “C”) Calories are the ones used to describe the amount of energy contained in foods. The (small “c”) calories are defined as the amount of energy it takes to raise the temperature of 1 gram of water 1 degree Celsius.

It takes one calorie to raise the temperature of 1 kilogram of water 1 degree Celsius. For example when you consume a 140-Calorie drink, you are actually ingesting 140,000 calories. Don’t panic about the 140,000, the conversion from Calories to calories applies across the board. When you burn 100 (Big “C”) Calories, jogging or cycling or whatever, you are burning 100,000 (small “c”) calories.

The definition of a calorie is based on raising the temperature of water, so it is safe to say that as your body warms up the liquid, it’s burning calories to do so.

Here is an example of what a typical person might burn when they 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 to be around 36-38 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 somewhere between 36-38 Celsius. So in this example lets assume that the body’s normal state is around 37 Celsius, so the body would burn roughly 17,508 calories or 17.5 Calories to warm the liquid up.

Now 17.5 Calories doesn’t seem that significant, but if you drink more cold liquid beverages, you will of course burn more calories.  If you were to drink 4 16 oz of ice cold water daily, which turns out to be the recommended daily intake of water (8 8 oz of water), you would be burning an extra 70 Calories.
