How much water should you drink for each pound you are overweight?

No matter how much one weighs (thin, medium or heavy) it's 8 - 8 ounce glasses of water per day. The only time you may need more water is if you are jogging or exerting yourself or become dehydrated by hot weather. Too much water isn't good for you either. Drinking that 8 glasses of water a day is flushing out toxins and fats in the body and keeps the kidneys in good shape.
