Calcium is found to be good at helping weight loss.  It is good at reducing hunger and studies have shown that calcium stored in fat cells in the body play an important role in regulating how fat is stored and broken down by the body. More calcium in a fat cells means more fat will be burned.  It is also assumed that when a person is calcium deficient, the brain detects this and compensates by telling your body that it needs food, which works against someone who is trying to lose weight.  A research found that when women who were calcium-deficient took a supplement, they lost 4 times more weight than women who didn't take a calcium supplement.  Foods that are rich in calcium include low-fat yogurt, milk, beans, and dark leafy greens.
