A human being can live without food for more than a month, but no one can stay alive for more than a week without water! All living things need water for their bodies to function. When you take in food, water helps to dissolve it and, along with certain chemicals in your body, it turns this food into energy for you to grow. These chemicals can work only in water.
Also, water is needed to carry the wastes out of your body as well. Since you lose water as you breathe and sweat, you have to have about 21/2 quarts of water a day to stay healthy. This can come from drinking water or other beverages, and from water contained in the food you eat. Human being's body contains 65% water.
Now since we know we need water to survive does it help with weight loss? The answer is yes and no! Since we know we need 2.5 quarts of water a day, will you lose more weight if you drink more water? No, but it does help flush your system, and if your drinking water which is zero calories in place of any other drinks that do ....weight loss! Two full glasses of soda EVERY day helps you pack on an extra 24 lbs per year!
The benefit of drinking more water that really can aid in your healthy journey is simply this: Water does keep you hydrated, and might help you snack less. Sometimes thirst can be mistaken for hunger; if you're thirsty you may snack more. So the next time you think you might be hungry.....drink some water!
