How much water have you had today? The eight glasses a day theory has come under scrutiny, but we still need to stay hydrated, especially if we exercise and/or live in a hot, dry climate.
But there's another reason you want to keep hydrated; studies have found that folks who stay on top of their water intake actually consume fewer calories. This could be because sometimes we can confuse the feeling of dehydration with the feeling of hunger. So, in an effort to stay hydrated and keep your calories down, think about drinking a glass of water before your meals. You may find that you feel fuller faster, and if nothing else, it's a good way to guarantee you'll be drinking a few glasses of water a day.
