Whether you realize it or not most of us go through the day dehydrated (75% of Americans are chronically dehydrated). If you're one of those 25% who get enough water, good for you. You probably don't experience some of the daily symptoms of dehydration like hunger, fatigue, dizziness, heart burn, low cognitive performance, headache's and weight gain. Yes, weight gain. Studies have shown that drinking just 2 cups of water, before meals, helped dieters lose an extra 5 pounds yearly and maintain that weight loss.
I recently read a great article that talked about what you experience when your body needs more fluid. Dr. Mercola wrote, "Interestingly, the first sensation you'll experience as your body needs more fluid is hunger. This is why many weight loss experts counsel their clients to drink a glass of water when they think they want to eat, and then wait 20 minutes to see if they still feel hungry.
This helps train you to recognize the differences between feeling "real" hunger and beginning to need more water. The older you get, the more likely it is that you'll start to confuse hunger with thirst. The thirst mechanism in adults becomes weaker and often is confused with feelings of hunger."
If you know you're not getting enough water (6-8 glasses or 67% of your body weight in ounces), try this. Instead of heading straight for the pantry or, even worse, the drive-thru, drink 8-16 ounces of water and wait 20 minutes. Remember, being properly hydrated can also increase your metabolic rate as well as curbing unnecessary overeating.
