Depending on who you ask, we’re supposed to be drinking two to three liters of water each day (67-100 oz.). That means you’re still not drinking enough! (Your daily two quarts = 64 oz.) We also get water as a byproduct of metabolism, so you’re probably OK at two quarts, unless you do a lot of caffeine.
What that tells me is you have been running dry for way too long, and I would guess that since you’ve decided to start hydrating yourself properly, your body is operating much more efficiently now. You’re not experiencing a “buzz”, you’re just just not feeling run down from dehydration any more.
A dehydrated body isn’t happy. And it draws from other places to compensate for not having enough elsewhere. Water is taken mostly from inside your cells. Some is taken from outside the cells of your body, and 8% is taken from your blood volume. This causes your body to close some smaller vessels, called capillaries, and makes your blood thicker and harder to pump around your body. This has implications in hypertension, high cholesterol, and heart disease. Lack of water is also linked to, and currently being studied for, its role in headaches, arthritis, and heartburn.
A dehydrated state has clearly been linked to obesity. Without water your body cannot degrade a triglyceride (visualize lard) into usable forms for energy. Since a dehydrated state first pulls water from inside your body’s cells to compensate elsewhere, you have less water in your fat cells to liberate fat for energy, and so use less.
Water is also a natural appetite suppressant. When your stomach is full of anything it sends signals to the brain saying, “Woah there fellow, we’re full.” Overweight people need to drink more water than thinner people do. This is due to an increased metabolic load.
There is a lot more fat to be metabolized, and drinking enough water will make the kidneys’ job easier. In a dehydrated body the liver is forced to do some of the kidneys’ work and so can’t metabolize fat or cholesterol as efficiently. If you are trying to decrease the amount of fat on your body, you must drink water liberally, between two and three quarts a day.
