On the average, a person should drink eight 8-ounce glasses every day. That s about 2 quarts. However, the overweight person needs one additional glass for every 25 pounds of excess weight. The amount you drink also should be increased if you exercise briskly or if the weather is hot and dry. Water preferably should be cold it s absorbed into the system more quickly than warm water.
Some evidence suggests that drinking cold water actually can help burn calories.
Ideally a person drinks a glass or two of water at a time. Space these drinks out over morning, noon, and evening. When the body gets the water it needs to function optimally, its fluids are perfectly balanced. When this happens you have reached the breakthrough point. More fat is used as fuel because the liver is free to metabolize stored fat.
