Does drinking ice cold water burn calories?

Answer 1

Does drinking freezing cold water burns Calories?Yes, drinking cold water will burn a small number of Calories. Yes , but how many?If you drink water at body temperature, you will neither gain nor lose calories. However, if you drink cold water, your body will burn calories warming up the water.

First it is important to note the difference between a calorie and a Calorie. By definition a calorie is the amount of heat required to raise the temperature of one gram of water by one degree Celsius at one atmosphere pressure. What we commonly call a Calorie (with a big C) is actually a kilocalorie, or 1000 little calories.

Since body temperature is 37.5 degrees Celsius and there are apx 997 grams of water in a liter, we burn about 37,000 calories (37 Calories) for every liter of almost freezing ice water we drink.

If we drink the recommended 8 cups/2 liters of water per day, 74 calories isn't much compared to a 2000 Calorie a day diet, but over a year that's around 27,000 Calories burned just by drinking your water ice cold instead of warm!
