“Water helps cleanse your liver and kidneys, allowing your body to excrete hormones efficiently,” says Warner. “It also tames cravings – a craving is often a sign of dehydration, not a cry for food.” Warner says drinking two to three liters of water a day burns 50 to 75 additional calories and speeds up your metabolism.
Water has even more weight loss power when you drink it in place of other higher calorie beverages like soda or sports drinks. And, some studies show that gulping down two glasses just before a meal may even help you eat less.
Your daily game plan: Drink 2-3 liters (about 8-10 cups) of water a day, and sub in water for at least one 8-ounce can of soda or juice a day (about 150 calories) to drop a pound this month.
