You know you need to be drinking more water, and for good reason. Water flushes toxins from your system, regulates body temp, acts as an insulator for joints, prevents kidney stones, and supplies the body with a raft of crucial minerals, says Marietta Amatangelo, R.D., of Germantown, Md. "Without water, none of the other super-foods would matter."
Although water helps in every way, it may be at its most powerful when it comes to weight loss. Drinking a glass or two of water a half hour or so before mealtime, for example, can help take the edge off your hunger.
Getting in all that water each day seem like a drag? Try making a half gallon of sugar-free lemonade you can sip throughout the day, or buy a pack of calorie-free flavorings to add to your water bottle at work.
