Did you know that drinking cold water versus room temperature water can help you lose weight?
A couple of facts:
- Your body burns calories warming up the water in your body
- A calorie is defined as the amount of energy it takes to raise the temperature of 1 gram of water 1 degree Celsius.
- A Calorie, or kilocalorie, are what we normally think are calories (so whatever number you’re thinking, divide by 1000)
According to Discovery Health, 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 remember, we have to divide by 1000, so that’s only 17.5 additional Calories burned by drinking ice water versus room temperature water.
Multiply that by the 8 glasses of water you should be drinking a day and over time, 70 additional Calories burned a day adds up. If you drink ice water for one year instead of room-temperature water, you can lose up to 9 pounds of fat alone. 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!
