Hydration, maybe; weight loss, doubtful

Does drinking ice water burn more calories than drinking room-temp water?



It’s true that when you drink ice water, your body uses energy (calories) to raise the liquid’s temperature to body temperature. But not very much. Roger Clemens, DrPH (doctor of public health) in nutrition and biological chemistry, and associate director of regulatory science at the USC School of Pharmacy, walked us through the math. For the sake of simplicity, he didn’t take thermodynamics into account, which would change the numbers very slightly.

You have an 8-ounce glass of ice-cold water in front of you. That’s about 240 grams of water.

When you drink the ice water, which is roughly 4 degrees Celsius, your body will expend calories to bring it to body temperature, which is about 37.5 degrees Celsius; that’s a difference of 33.5 degrees. To raise 1 gram of water 1 degree Celsius, 1 calorie is expended. (This is a “little” calorie—what scientists use to measure small units of energy. The calories we refer to colloquially are actually 1,000 of these and are known as kilocalories in the science world.)

Raising 240 grams of water by 33.5 degrees Celsius will take 33.5 calories x 240 grams of water, which equals 8,040 little calories.

Dividing 8,040 by 1,000 gives us 8.04 food calories (kilocalories). Therefore, you’ll burn about 8 calories for each glass of iced calorie-free beverage you drink. That’s equal to about one Life Saver: not exactly a weight-loss miracle.

Using Clemens’s figures, it would take about 435 8-ounce glasses of ice water to lose a pound.

And do we have to tell you? Consuming large quantities of cold water can have serious health effects, such as an overall lowering of body temperature, a decrease in the functionality of the gastrointestinal tract, and, in extreme cases, anemia. Drinking a lot of water can also lead to water intoxication.

I have heard and read that drinking warm water aids in digestion and keeps the digestive system active...Chinese do the same in order to keep themselves healthy..Because, apparantly, if your digestiver system is working fine, your metabolism would be in good shape and thus, you would burn the fat faster...However, cold/iced water actually slows down the process of digestion which leads to slow metabolism rate..Conclusion? No, drinking iced/cold water doesn't help at all...I hope it would help ya!

v should adopt da habbit of drinking hot or warm water

The energy consumed in going to the source e.g water cooler, pouring into water and then bringing the glass of water to your mouth and the the energy consumed in drinking it , should also be accounted for. It will easy mean that you can burn at least 50 calories in the effort to get and then drink the water. No ?

no ice water is simply trash...slows down the digestion..it doesnt help at all and wud in turn increase the size of ur belly simply...water at room temp is the best ..warm water is also good..here in jeddah no mater how hot the weather is i always drink room temp water..means warm water and it really satisfies..bcz u cant drink cold water alot..after a few seconds u wud feel some shivering..even cold milkshakes r not good..they induce constipation...ice-creams r also not a good idea..they make u bulky as well as its 85% air! so u r consuming the calories but its of no use at all!
what the hell !
