Does drinking ice water burn calories?
If you are trying to lose weight the title of this post is an exciting one! If you simply want to know if your body burns calories and warms the water you drink the answer is YES. How about drinking ice water ? I think ice water is more efficient in weight loss.
Do not believe me. Lets do some calculations to authenticate my point of view.
First of all, calories are case-sensitive. There are calories and then there are CALORIES. CALORIES are the ones used to describe the amount of energy contained in food. A calorie (written in lower case) is defined as the amount of energy it takes to raise the temperature of 1 gram of water through 1 degree Celsius.
CALORIE (contained in food) is actually a kilo-calorie: It takes one CALORIE to raise the temperature of 1 kilogram of water through 1 degree Celsius. So when you drink a 140-Calorie can of cola, you are ingesting 140,000 calories. There is no need to be scared, because the conversion applies across the board. When you burn 100 CALORIES jogging a mile, you are burning 100,000 calories.
So, considering that the definition of a calorie is based on raising the temperature of water, it is safe to say that YOUR BODY BURNS CALORIES when it has to raise the temperature of ice water to your body temperature. And YOUR URINE IS NOT COMING ICE-COLD, so your body must be raising the temperature of the water. So calories are being burned (by ice-cold water).
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 or 98.6 degree Fahrenheit
- It takes 1 calorie to raise 1 gram of water through 1 degree Celsius.
- There are 473.18 grams in 16 fluid ounces of water. (1 fluid ounce = 29.5735 grams)
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. 473.18 multiplied by 37 = 17,508 calories
But that’s calories not CALORIES. Your body only burns 17.5 CALORIES, and in the whole day diet of a 2,000-Calorie, that 17.5 isn’t a very significant figure.
Now let us go to a real-life picture- an 8×8 rule in case of drinking water. Although 8×8 rule does not have a hard evidence but it is still very common because it is easy to remember. It is recommended that we should take 8-ounce glass of water at least 8 times in a 16 hour day,excluding 7-8 hours of sleep time.
64 fluid ounces of water equals 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!
Lets do some more calculations to understand this question of losing weight.
1 Kilogram is equal to 2.2 pounds which is equal to roughly 7716 cals. So if 70 calories are lost in one day, 25550 cals are lost in a year which is almost 7 pounds. 7 pounds weight loss a year just by drinking ice-cold water can save a lot in terms of expenses like gym,weight loss pills and so on. Although these calculations are not accurate to the decimal points,7-8 pounds a year is a good estimate in terms of weight loss.
SO GO AHEAD: CONGRATULATIONS : LOSE WEIGHT BY DRINKING ICE-COLD WATER,OFF COURSE WITH DIET CONTROL, EXERCISE ETC.
