Drinking lots of water is commonly espoused in weight loss regimens and is regarded as healthy; however, few systematic studies address this notion. In 14 healthy, normal-weight subjects (seven men and seven women), we assessed the effect of drinking 500 ml of water on energy expenditure and substrate oxidation rates by using whole-room indirect calorimetry. The effect of water drinking on adipose tissue metabolism was assessed with the microdialysis technique. Drinking 500 ml of water increased metabolic rate by 30%. The increase occurred within 10 min and reached a maximum after 30–40 min. The total thermogenic response was about 100 kJ. About 40% of the thermogenic effect originated from warming the water from 22 to 37 C. In men, lipids mainly fueled the increase in metabolic rate. In contrast, in women carbohydrates were mainly used as the energy source. The increase in energy expenditure with water was diminished with systemic ß-adrenoreceptor blockade. Thus, drinking 2 liters of water per day would augment energy expenditure by approximately 400 kJ. Therefore, the thermogenic effect of water should be considered when estimating energy expenditure, particularly during weight loss programs.
Very cool. I've been doing this for a while as well. However, I often wonder about ancient Chinese medicine and it's thought that you shouldn't drink ice water. My father, who has traveled to China frequently over the last three decades - and doesn't believe in naturopathic medicine - once had his pulse taken by a Chinese physician. There is an entire science in every medical tradition BUT modern Western allopathic, of 'reading' the pulse to diagnose the body. The doctor said he could tell right away that my father drank ice water - cold ice water, which is one thing he does frequently. He also indicated that he thought this was one of the causes of his chronic bowel distress, stating that it is not good for the body to drink ice cold drinks.

Yes, the colder the better. The colder the water is, the more your body has to warm it up after ingestion. The more it has to warm it up, the more it is burning kcals.
Interesting story Kaiser. I'll start paying attention now whether or not there is a correlation between drinking ice water and needing to fumigate my home [img]tongue.gif[/img]
I've always chewed my ice, in addition to drinking the water. While it's tacky to do in public, I'm convinced it has helped me remain cavity-free my entire life. Cleans the teeth [img]smile.gif[/img]

Except that chewing ice, if you have fillings, is a sure way to crack your teeth. The filling metal will expand and contract at a different rate than your bone (teeth).... and, oilå, cracked tooth where part of it falls out. 4 out of 5 dentists say that you shouldn't chew ice. The 5th one needs more business...
