Water and milk are essential fluids for good health, but they can also help with shedding pounds.

The body needs water to keep properly hydrated and individuals vary widely in how much water they need. Joints need it to stay in motion, and vital organs such as the heart, brain, kidney, and liver need it to work properly.

If you don't get enough water, the body goes into emergency mode, and clings to every single water molecule it can find, reports the University of Minnesota Water Resources Center. The stored molecules appear as extra weight. The weight is only released once the body gets enough water.

The calcium in dairy, on the other hand, is known to be important for strong bones and teeth. Studies have also shown it can help prevent high blood pressure, kidney stones, heart disease, and colon cancer.

In the weight loss arena, three 8-ounce glasses of low-fat or fat-free milk appear to encourage body fat loss while maintaining muscle mass, according to the ADA. The dairy consumption must be part of a balanced reduced-calorie meal plan.
