Want to lose some weight overnight? You definitely can! The catch is that it won’t be fat, but it will be extra water weight that you are holding onto. Water weight can account for several unwanted pounds around your midsection as well as around your entire body. The trick to decreasing this extra water weight is to cut back on your sodium (aka salt) intake. Salt attracts water and so the more salt you have in your body, the more water you are going to hold onto.
