Here's a Snopes article about the water myth. They're the site that busts urban legends.
http://www.snopes.com/toxins/water.htm
Eating a low carb diet you do carry around a lot less water load, and I was always thirsty while on Induction. So I drank a fair amount of liquid. But generally, I trust my body to tell me when it needs more water. But I'm usually sipping on something all day long simply from habit.

Kidney specialists do agree on one thing, however: that the 8-by-8 rule is a gross overestimate of any required minimum. To replace daily losses of water, an average-sized adult with healthy kidneys sitting in a temperate climate needs no more than one liter of fluid, according to Jurgen Schnermann, a kidney physiologist at the National Institutes of Health.

Quote:
Doctors from a wide range of specialties agree: By all evidence, we are a well-hydrated nation. Furthermore, they say, the current infatuation with water as an all-purpose health potion — tonic for the skin, key to weight loss — is a blend of fashion and fiction and very little science.
Regular coffee and tea drinkers become accustomed to caffeine and lose little, if any, fluid. In a study published in the October issue of the Journal of the American College of Nutrition, researchers at the Center for Human Nutrition in Omaha measured how different combinations of water, coffee and caffeinated sodas affected the hydration status of 18 healthy adults who drink caffeinated beverages routinely.
"We found no significant differences at all," says nutritionist Ann Grandjean, the study's lead author. "The purpose of the study was to find out if caffeine is dehydrating in healthy people who are drinking normal amounts of it. It is not."
The same goes for tea, juice, milk and caffeinated sodas: One glass provides about the same amount of hydrating fluid as a glass of water. The only common drinks that produce a net loss of fluids are those containing alcohol — and usually it takes more than one of those to cause noticeable dehydration, doctors say.
The best general advice (keeping in mind that there are always exceptions) is to rely upon your normal senses. If you feel thirsty, drink — if you don't feel thirsty, don't drink unless you want to. The exhortation that we all need to satisfy an arbitrarily rigid rule about how much water we must drink every day was aptly skewered in a letter by a Los Angeles Times reader:
Although not trained in medicine or nutrition, I intuitively knew that the advice to drink eight glasses of water per day was nonsense. The advice fully meets three important criteria for being an American health urban legend: excess, public virtue, and the search for a cheap "magic bullet."

Another article with a reference:
Quote:
New research from Dr. H. Valtin of Dartmouth Medical School indicates there is little scientific evidence to support the theory that a human should consume at least eight cups of water a day under normal circumstances.
In fact, drinking too much water can cause a serious condition characterized by a lack of salt in the blood, leading to water imbalance and water build-up in the brain. Hyponatraemia actually means low (hypo) sodium (natr) levels in the body.
