Water Helps Metabolize Fat
Without enough water, the kidneys can't function properly. When this happens, some of the load is transferred to the liver. The liver metabolizes stored fat for energy. If the liver is doing some of the kidneys' work, it burns less fat. In addition, water can actually reduce feelings of hunger.
If you are struggling to get enough water in to your lose weight dies, I recommend mixing two scoops of Scivation - Xtend with 500ml of water, as it greatly increases the taste, and doubles the benefits. You'll be getting water and BCAA.
