“You should drink 8 glasses of water (64 oz.) a day” that’s what all the healthy people say. Pop and coffee doesn't count. (Damn!) well why is this?
  1. It will help you get fit: water suppresses the appetite and helps you to metabolise stored fat.
  2. You are always running out of it: About 60 percent of your body is water, and you must constantly replenish the supply or your body will retain water making you feel bloated.
  3. It may make you smarter: if you’ve lost 2 percent of your body weight in water, your brain power and performance level may start to weaken.
    1. If you eat a lot of fruit and vegetables you may not need a full 8 glasses . . . but it can’t hurt:
      Bob Condor, Chicago Tribune, May 16, 1994
      A suitable allowance of water for adults is 2.5 liters (83 ounces) daily in most instances, the book states. An ordinary standard for diverse people is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods.

      Somehow, the final sentence was lost in the translation. Most doctors and nutritionists say people don't need to drink every one of those eight glasses of water if they eat the proper foods.
