- garrettgjb, on 10/12/2007, -1/+96Want to exercise today? Nah I drank some ice water earlier.
- inactive, on 10/12/2007, -8/+93Thanks for giving us a completely unrelated factoid in a desperate attempt to sound smart.
And for the record, you dont "metabolize" water, you *****. - CatalystDM, on 10/12/2007, -6/+71^dugg for *****
- Roger, on 10/12/2007, -3/+52"*****" is the word of the day.
(everyone scream!) - PlasmaSnk, on 10/12/2007, -2/+39Peeing burns calories too right? I mean you have to get up and go to the bathroom... so it's like super exercise.
- calebhawk, on 10/12/2007, -21/+50drinking ice water = shrink calorie count
sitting in ice water = shrink male parts - Roger, on 10/12/2007, -1/+21Why?
Calories are a unit of energy. And it takes energy to heat ice water to body temperature.
Hence you burn calories. - DreKor, on 10/12/2007, -1/+20Your body doesn't NEED to do anything to the water before it uses it. Thermodynamics says that that it's just going to warm up because you're already warm.
- CatalystDM, on 10/12/2007, -0/+19yeah, I took high school physics too!
- fordhamwt, on 10/12/2007, -0/+13@Lumiras --The girls in bikinis were skinny to begin with...the bikinis did not make them thin.
Now isn't that the ultimate chicken/egg dilemma. - frant1c, on 10/12/2007, -2/+14I have no idea what "*****" means.
But I love it. - CatalystDM, on 10/12/2007, -2/+14I think it was a joke.
- Roger, on 10/12/2007, -0/+10Actually water can exist at 0C and still not be ice.
- saska, on 10/12/2007, -1/+10So if I drink 60 8-oz glasses of water I can burn off that Quarter Pounder with Cheese!
...Could I, like, die from this? - Lumiras, on 10/12/2007, -5/+14you're wrong, sorry.
The girls in bikinis were skinny to begin with...the bikinis did not make them thin.
Besides, there are plenty of girls on the beach wearing bikinis that really shouldn't be - coder316, on 10/12/2007, -0/+6i just drank a lot of iced-water and now i have a stomach ache :-(
aww *****! - Nitelite, on 10/12/2007, -1/+6Jumping on the ***** bandwagon now. Tomorrow it'll be old news. =(
- sacherjj, on 10/12/2007, -0/+5You sweat as a by product of aerobic respiration. It also evaporated to help you cool. The only disadvantage of drinking cold water is if it causes cramping. Otherwise, basic thermodynamics would explain how it helps cool your body that is being warmed up by activity and aerobic (or anaerobic) respiration.
- calebhawk, on 10/12/2007, -1/+5pooping is the fastest way to lose weight
- krazytom, on 10/12/2007, -1/+5People with a college degree probably(hopefully) realize the fact that your body heating up the water uses calories.
But I don't think it's obvious you could be burning 70 calories/day. Which is about a .6/lb of fat burned a month if you drink 64 ounces of ICE cold water every day. - wilf_brim, on 10/12/2007, -0/+4This article overlooks one very important fact. The human body produces waste heat. We are fairly inefficient at turning food energy into electrical or mechanical energy. Most of the excess is given off as heat. Some is necessary to maintain normothermia, but most of more than we need, and is given off either by respiration or through the skin (perspiration or direct radiant heat).
Drinking cold water just means that more of that energy that would otherwise been radiated will go to bringing the liquid to body temperature. Sorry folks, exercise and cutting down on the food is still the only way to go. - jlunski, on 10/12/2007, -0/+4Time to start banning/blocking all these "will it blend" idiots.
- lazyrussian, on 10/12/2007, -3/+7Yup he is right. Q = mcdT
Q = Heat (measured in Calories/kCal)
m = mass of water
c = specific heat of water
dT = Change Temperature (Say from 98.6 F to 32 F // 310 Kelvin to 273 Kelvin)
Since your body is at 98.6 Fahrenheit usually, it will take quite a bit of energy to heat the water so that it will be equibvalent to your body temperature. - noamsml, on 10/12/2007, -0/+4No, it doesn't.
- starm69, on 10/12/2007, -0/+4As long as you don't dress warmer to offset the coldness of the water. The key thing here is that being cold makes you burn calories. You could achieve the same effect by lowering the temperature of your room and making your body work to produce heat. And you'd be saving energy, money and the environment!
- Roger, on 10/12/2007, -1/+5We should just blend them.
- Roger, on 10/12/2007, -0/+3@asimo8
Thats true, but more importantly you need to remove energy from 0C water to make it 0C ice.
Its not just because of impurities. - bmartin, on 10/12/2007, -2/+5I did the math: It turns out that if you drink 8 glasses of 0 C water for an entire year, assuming it's all heated up to body temperature, you'll burn about 7.1 lbs (assuming fat is metabolized, 3600 Calories per lb). You're much better off sitting in a pool for an hour a day.
- Nitelite, on 10/12/2007, -0/+2This sounds crazy, but I'm trying this right now.
.. your reply didn't include where to put the "excess", now I have to go home from work to change. - markp93, on 10/12/2007, -0/+2odd image FTA:
"And unless your urine is coming out ice cold, your body must be raising the temperature of the water." - rjmatm, on 10/12/2007, -0/+2@lazyrussian

dT = Change Temperature (Say from 98.6 F to 32 F // 310 Kelvin to 273 Kelvin)
You didn't do the problem so you don't see what it really means.
Using temp. in Celcius (0 to 37).
To burn 454g of fat (approx. 1lb.) would require about 3500x(10^3) cal transfered to the ice water.
Reconfigure the equation to this:
m=(Q)/(c*dT)
You will see that to burn 454g of fat (approx. 1lb) you will need to drink about 94.6gx(10^3)g of water or 94.6 Liters of water.
When you look at the conversions that comes to about 24.97 gallons of water to burn 1 pound of fat.
Not a very realistic diet plan. - stoppedcode12, on 10/12/2007, -0/+2Not more than what you are taking in.
- dustyshadow, on 10/12/2007, -1/+364 ounces of ice water a day is actually way more than most people drink. It seems like a lot of work to burn very few calories. you are probably better off just getting up and walking around the room for 5 minutes twice a day.
- listrophy, on 10/12/2007, -0/+2Actually, (pure or slightly impure) water need not freeze at 0C at ambient pressure. See supercooling water: http://en.wikipedia.org/wiki/Supercooling
Basically, water needs a seed crystal to build the ice structure. According to the article, you can supercool water below -40 degrees without forming ice. It's really hard to do that without very clean conditions, but a few degrees below freezing should be perfectly achievable in a cold garage. Introduction of a mechanical perturbation or seed ice crystal results in rapid crystalization. - jordan314, on 10/12/2007, -0/+2So if you go out in the cold and stand around, does your body burn calories warming itself back up?
- MrSunshine, on 10/12/2007, -1/+3But don't forget that drinking too much water can kill you. Or maybe you're already frozen before that.
- soogy, on 10/12/2007, -0/+2"Wooosh!"
Whoa! What was that? - KloroFormd, on 10/12/2007, -0/+2asimo8: Correction, pure water will freeze at 0c if it's at sea level. Under pressure, it has to be colder.

"While (I thought obviously) the "observe the beach" part was a joke - the other part isn't.
Less insulation == heat leaving the system == more calories needed to maintain body temperature.
Before modding it down, can anyone explain why they'd think it isn't true?"
It's not true because a body that is trying to cool itself down is not using any calories to stay warm
Less insulation == heat leaving the system == less work by the system to stay cool - mckinnej, on 10/12/2007, -0/+2That's pretty much the same thing I was thinking. The real test would be to see if the body actually throws some more coal on the fire to heat the water or if the water is just heated with energy that would have otherwise been radiated into the atmosphere. If there isn't some sort of physiological signal indicating an increased energy burn after drinking the water, then the water is being heated by what would have been excess (waste) heat.
- jlunski, on 10/12/2007, -0/+2So if I want to help lose weight am I better off drinking hot green tea or ice cold water?
- jlunski, on 10/12/2007, -0/+1It's just you.
- commiecat, on 10/12/2007, -0/+1What's all this talk about water? 80-proof alcohol runs about 64.5 calories per ounce. So you're taking in 516 calories for 8oz. of, say, gin.
Get that gin ice cold. 0 degrees Celsius cold. Google tells me that 8 ounces is about 226 grams. Now you have to take those 226 grams and raise them 37 degrees Celsius.
You consume 516 calories of gin. You burn 8362 calories bringing it up to body temperature - not even including the calories you'd burn bringing any ice/water up as well. Get wasted AND lose weight!
Yes I know the whole big/little "C" thing make a huge difference. This makes weight loss so much more appealing, though. :) - wvdavis, on 10/12/2007, -0/+1Etymology - A humorous misspelling of *****.
Noun - *****
1. (slang) An isolated or backward location.

http://en.wiktionary.org/wiki/***** - ubuwalker31, on 10/12/2007, -1/+2I tried explaining this to a secretary where I work, and she refused to believe it. She is always going on about the latest fad diet, and has no understanding of how the body works. Or a grasp of physics. There is a combination of effects going on when you drink water. Stating "your body must raise the temperature of 473.18 grams of water from zero to 37 degrees C" vastly simplifies what happens, but is basically correct. The water "robs" your insides of energy which your body must replace. Eventually, the water reaches body temperature. This energy comes from your body and the environment. You probably burn less than 60 kcals warming up 8 cups of ice water, but not much less.

"you're wrong, sorry.
The girls in bikinis were skinny to begin with...the bikinis did not make them thin. "
Did the cluetrain left you at the station Mr. Obvious? - argblat, on 10/12/2007, -0/+1A great piece of advice that I once received that is along the same lines as this concept:
If you are ever cold (especially your feet or hands), take a pee.
Because your body has to maintain 98 degrees Fahrenheit, it wastes excess energy keeping all that useless waste warm inside your bladder.
The second you remove it from the equation your body can re-route the energy to keeping your extremities warm ... such as your feet and hands. - squirrelza, on 10/12/2007, -0/+1I might be slightly wrong, but it does reduce fat and clear the digestive system.
- TheConsigliere, on 10/12/2007, -0/+1roger's statement is accurate regardless of altitude (although altitude and pressure do determine the temperature at which phase change occurs). Even at sea level we could cool the water down to 0 degree C and it would not suddenly turn to ice. Changing liquid water to ice requires further transfer of energy out. The graph at the URL below gives the typical temperature profile of water when energy is constantly transfered into it.

I had always knew that drinking ice water burned calories, but I thought the amount was marginal. On the other hand, 70 calories a day isn't an insignificant amount for something that's so easy to do
