And women who consistently limit what they eat to avoid gaining weight may undermine the health of their bones, according to a study by ARS researchers in California. (1)

The study looked at the eating behavior of women between the ages of 18 and 50 and found that those classified as "restrained eaters" had significantly lower bone mineral density and bone mineral content (key indicators of overall bone strength and health) than women who said they weren't concerned about what they ate.

"Exercise and eating a well-balanced diet with adequate calcium, are two of the best ways to keep your bones strong and healthy." advise the researchers.

Calcium is not only good for your bones but can help you maintain a healthy, low fat diet too. There has been increasing media coverage about numerous studies showing that a diet rich in calcium helps reduce body fat.

Why is calcium important in weight loss?

Calcium is a fat burner. High-calcium diets seem to favor burning rather than storing fat. Researchers say this is because calcium stored in fat cells plays an important role in fat storage and breakdown.

Calcium changes the efficiency of weight loss . In fact, study after study has shown that the people with the highest calcium intake overall weighed the least, and the people with the lowest calcium intake had the highest percentage of body fat. (2,3,4)

When overall calorie consumption is accounted for, calcium not only helps keep weight in check, but can be associated specifically with decreases in body fat. A low daily calcium intake is associated with greater tendency to gain weight, particularly in women. (5)

Researchers found that adolescent girls who consumed more calcium weighed less and had less body fat than girls who consumed the same amount of calories from other sources. (6)
