A recent study from researchers at the Massachusetts General Hospital, and published in the American Journal of Clinical Nutrition, has found that taking daily supplements of calcium plus vitamin D might help you lose fat around your waist.
The researchers conducted a pair of double-blind clinical trials that ran simultaneously with each other for 16 weeks. During both the studies, participants were asked to drink 3 full 8-oz. glasses of orange juice every day.
In one of these twi trials, though--let's call it the standard trial--all the participants (whether in the treatment group or the control group) drank standard orange juice, with "standard" here meaning juice from which none of the calories has been removed.
In the other trial--let's call it the lite trial--all participants were given a reduced-calorie (lite) orange juice--the kind that's had some of the calories removed during processing.
The crucial thing to know is that the people in the treatment arms of both these studies received orange juice that had been fortified with calcium and vitamin D. Those in the control groups of both studies, however, drank juice that had not been fortified.
The fortified juices used in both the studies--whether regular juice or lite--provided a total daily dose of 1,050 milligrams (mg) of calcium and 900 International Units (IUs) of vitamin D. (To put this into perspective, the recommended daily allowance (RDA) for calcium for adults aged 19-50 is 1,000 mg per day, and 600 IUs per day of vitamin D.)
Because in both the standard trial and the lite trial, the participants who drank the fortified juice (those in the 2 treatment arms) experienced significant reductions in the volume of their visceral fat deposits. In contrast, those in both the control arms, who didn't get fortified juice, lost only minimal or no appreciable amounts of visceral fat.
And these results are important was well because, if you are overweight, losing visceral fat from around your middle is a wonderful thing to do for your health. Unlike the subcutaneous fat that's found just below the skin's surface, your visceral fat is deposited deeper inside the body, around the internal organs, and many studies have linked it to a significantly higher risk of heart disease and metabolic problems
