Research is mixed. Some studies have not found a relationship between calcium intake and weight loss. However “there have been several studies that have shown benefits from three daily servings of low-fat dairy foods including weight loss� says Toby Smithson RD national spokesman for the American Dietetic Association. Those studies “showed more weight loss from low-fat dairy foods combined with a reduced-calorie diet than from calcium supplements� Smithson notes. That''s not to say calcium supplements might not help you in your weight loss efforts.
