We do take in some liquid in our food; sometimes quite a substantial amount. You will usually get about 3 1/2 cups of fluid from what you eat during the day. Your body also generates about 1/2 a cup of fluid as part of your metabolic processes.
Since we lose ten cups of water a day and only get four cups from food and metabolism, it is obvious that we need to drink at least six cups per day just to equal it out. You’re better off if you can drink the recommended eight glasses of water.
All of the liquid that you drink doesn’t have to be in the form of water. You can drink skim milk, unsweetened juices or other non-caffeinated beverages.
Heat, exercise and diet can all make a difference as to how much liquid your body actually needs. You’ll need to take in more fluids if you eat potato chips for a snack rather than an orange
Getting your full quota of liquids does more than conserve the energy your body uses. It also burns fat. Added benefits are the increased ability for your body to fight tension and fatigue.
Sometimes we think we are hungry when we are really thirsty. That’s when we are more likely to eat high-fat snacks. A good way to tell whether you are hungry or thirsty is to drink a glass of ice-cold water when you feel hungry. Wait a few minutes to see if your "hunger pangs" have been satisfied.
Drinking water has been shown to eliminate food cravings and reduce appetite. When you drink plenty of liquids throughout the day, it takes up space in your stomach, helps you feel full and reduces your desire to eat.
