Weight Loss Forum / General Topics / July 2004Drinking Water
There is an intersting article in August's prevention magazine. Researchers in Germany measured the resting metabolism of 14 men and women before and after they drank just over 16 ounces of water. Within 10 minutes, metabolism began to rise. After 40 minutes, the volunteers'average calorie-burning rate was 30% higher, and it stayed elevated for more than an hour. Researchers don't understand why, but they calculate that drinking eight 8-ounce glasses of water a day can burn off 35,000 calories a year, or about 10 pounds.

Let's see. 35000 c/year is 95 calories per day. One calorie is amount of energy required to warm one gram of water by one degree C. What we talk about when we say calorie in the us is in fact a kilocalorie, or 1000 "real" calories. 64 ounces of ice water (say 5 degrees C) would be heated to 37 degrees C. 1792 grams x 32 degrees = 57344 calories, or 57 US calories So, 57 out of those 95 calories is simply thermal effect of warming up the water inside the body. I am surprised at saying that "researchers don't understand why", when at least 60% of the effect is explainable by trivial thermodynamics. Every high school graduate shoule be able to perform this simple calculation. The remaining 38 calories will be, likely, further explained by having kidneys to remove that water from bloodstream, etc. i Interesting, Ig, something I hadn't considered - burning calories to keep warm. In theory, I'd lose more weight in winter by running around outside, nekkid, and drinking ice water! - Dewolla > > There is an intersting article in August's prevention magazine. > > [quoted text clipped - 33 lines] > > i > Interesting, Ig, something I hadn't considered - burning calories to keep > warm.

My conclusion is that I would prefer to just eat less:) i > - Dewolla > [quoted text clipped - 39 lines] >> >> i > > I am surprised at saying that "researchers don't understand why", when > > at least 60% of the effect is explainable by trivial thermodynamics. > > Every high school graduate shoule be able to perform this simple > > calculation. actually the cooling effect doesn't "save" any energy, since the body cools itself via perspiration quite efficiently already. when you drink cold water you just sweat a little less. >> > I am surprised at saying that "researchers don't understand why", when >> > at least 60% of the effect is explainable by trivial thermodynamics.

Most people do not perspire very much, as most of their time is spent in air conditioned environment. i My doctor always stresses to drink room temperature water. When I questioned him, he said it was because the enzyemes in the stomach work best at body temperature, and drinking large quantities of cold water affect them. > >> > I am surprised at saying that "researchers don't understand why", when > >> > at least 60% of the effect is explainable by trivial thermodynamics.

I also prefer room temperature water, unless I am very hot. i >> In article <dd5de929.0407122157.646e6d0d@posting.google.com>, Heywood > Mogroot wrote: [quoted text clipped - 14 lines] >> >> i >Interesting, Ig, something I hadn't considered - burning calories to keep >warm.

Ally 212/172/160 To be serious, 8 glasses of water per day ain't enough. If you have 20 or more pounds to lose, try 8 gallons instead. |
