Does anyone know why we have to drink 8 glasses of water a day? What is the purpose? I always drink water no matter what at the office at least 6 glasses a day, i have always been like that!

But now that i am trying to loose weight, what is the purpose of 8 glasses of water a day when trying to loose weight?

Your body is estimated to be about 60 to 70 percent water. Blood is mostly water, and your muscles, lungs, and brain all contain a lot of water. Your body needs water to regulate body temperature and to provide the means for nutrients to travel to all your organs. Water also transports oxygen to your cells, removes waste, and protects your joints and organs.

How Much Water do You Need to Drink?

A good estimate is to take your body weight in pounds and divide that number in half. That gives you the number of ounces of water per day that you need to drink. For example, if you weigh 160 pounds, you should drink at least 80 ounces of water per day. If you exercise you should drink another eight ounce glass of water for every 20 minutes you are active. If you drink alcohol, you should drink at least an equal amount of water. When you are traveling on an airplane, it is good to drink eight ounces of water for every hour you are on board the plane. If you live in an arid climate, you should add another two servings per day. As you can see, your daily need for water can add up to quite a lot.

Twenty percent of your water need will come from the foods you eat. The rest of your water need should come from the beverages you drink. Water is the best choice. Sodas have a lot of sugar in them, so if you drink sodas, you may take in more calories than you need. Herbal teas that aren't diuretic are fine. Sports drinks contain electrolytes and may be beneficial, just look out for added sugar and calories that you don't need. Juices are good because they have vitamins and nutrients.

Caffeinated beverages will also add to your daily water need. Even though caffeine is a diuretic, if you regularly consume caffeine, your body will regulate itself to that diuretic effect.

Think of water for our bodies as the equivalent of oil for a car. The car can run on low oil, but it tends to cause damage to the engine. We can tenchnically live without enough water in our systems, but our bodies will not be as efficient as they could be, and weight loss will likely be more difficult. If the oil runs out completely, the car is going to die and is very expensive to fix - just ask my brother :laugh: Same thing with water in our bodies - if we get too dehydrated, it can have VERY serious health consequences! Here is a fantastic article about water: http://www.experiencelifemag.com/issues/june-2010/wellness/drink-to-your-health.php

Here is the most important section (in my opinion):

Why Water Matters

Even healthy eaters often underestimate the importance of their water intake and wind up suffering from chronic, low-grade dehydration. Here are just a few reasons good hydration is essential to good health:

Energy: Suboptimal hydration slows the activity of enzymes, including those responsible for producing energy, leading to feelings of fatigue. Even a slight reduction in hydration can lower metabolism and reduce your ability to exercise efficiently.

Digestion: Our bodies produce an average of 7 liters of digestive juices daily. When we don’t drink enough liquid, our secretions are more limited and the digestive process is inhibited. (Note that drinking too much water all at once, particularly with food, can also dilute digestive juices, reducing their efficacy and leading to indigestion.)

Regularity: As partially digested food passes through the colon, the colon absorbs excess liquid and transfers it to the bloodstream so that a stool of normal consistency is formed. When the body is low on water, it extracts too much liquid from the stool, which then becomes hard, dry and difficult to eliminate. Slowed elimination contributes to bodywide toxicity and inflammation.

Blood Pressure: When we are chronically dehydrated, our blood becomes thicker and more viscous. Additionally, in response to reduced overall blood volume, the blood vessels contract. To compensate for the increased vein-wall tension and increased blood viscosity, the body must work harder to push blood through the veins, resulting in elevated blood pressure.

Stomach Health: Under normal circumstances, the stomach secretes a layer of mucus (which is composed of 98 percent water) to prevent its mucus membranes from being destroyed by the highly acidic digestive fluid it produces. Chronic dehydration, though, impedes mucus production and may irritate and produce ulcers in the stomach lining.

Respiration: The moist mucus membranes in the respiratory region are protective; however, in a state of chronic dehydration, they dry out and become vulnerable to attack from substances that might exist in inhaled air, such as dust and pollen.

Acid-Alkaline Balance: Dehydration causes enzymatic slowdown, interrupting important biochemical transformations, with acidifying results at the cellular level. The acidification of the body’s internal cellular environment can be further worsened when excretory organs responsible for eliminating acids (e.g., the skin and kidneys) don’t have enough liquid to do their jobs properly. An overly acidic biochemical environment can give rise to a host of inflammatory health conditions, as well as yeast and fungus growth.

Weight Management: Feelings of thirst can be confused with hunger, both because eating can soothe thirst and also because dehydration-induced fatigue is often misinterpreted as a lack of fuel (e.g., sugar). Both dynamics can lead to false sensations of hunger, triggering overeating and weight gain. Inadequate hydration can also promote the storage of inflammatory toxins, which can also promote weight gain.

Skin Health: Dehydrated skin loses elasticity and has a dry, flaky appearance and texture. But dehydration can also lead to skin irritation and rashes, including conditions like eczema. We need to sweat about 24 ounces a day to properly dilute and transport the toxins being eliminated through our skin. When we are chronically dehydrated, the sweat becomes more concentrated and toxins aren’t removed from our systems as readily, which can lead to skin irritation and inflammation.

Cholesterol: Cholesterol is an essential element in cell membrane construction. When we are in a state of chronic dehydration and too much liquid is removed from within the cell walls, the body tries to stop the loss by producing more cholesterol to shore up the cell membrane. Although the cholesterol protects the cell membrane from being so permeable, the overproduction introduces too much cholesterol into the bloodstream.

Kidney and Urinary Health: When we don’t drink enough liquid, our kidneys struggle to flush water-soluble toxins from our system. When we don’t adequately dilute the toxins in our urine, the toxins irritate the urinary mucus membranes and create a germ- and infection-friendly environment.

Joint Health: Dehydrated cartilage and ligaments are more brittle and prone to damage. Joints can also become painfully inflamed when irritants, usually toxins produced by the body and concentrated in our blood and cellular fluids, attack them, setting the stage for arthritis.

Aging: The normal aging process involves a gradual loss of cell volume and an imbalance of the extracellular and intracellular fluids. This loss of cellular water can be accelerated when we don’t ingest enough liquids, or when our cell membranes aren’t capable of maintaining a proper fluid balance.
