While calcium’s bone-protective benefits have been long-established, calcium’s obesity-protective benefit has only recently been identified. For the past decade, studies have established that high calcium intake can reduce the risk of obesity and assist in making weight loss regimens more effective.  In 2003, a researcher estimated that with each 300 mg increment in regular calcium intake there is an associated image chart1 kg less body fat in children and 2.5–3.0 kg lower body weight in adults .  
Nonetheless, calcium’s role in maintaining healthy body weight remains controversial.  Consider the recent study conclusions:

  1. A diet rich in dairy calcium enhances weight reduction in Type 2 diabetics.
  2. Calcium plus cholecalciferol supplementation has a small effect on the prevention of weight gain - observed primarily in women who reported inadequate calcium intakes.
  3. Weight and fat weight loss resulting from 9 months of moderate intensity exercise may be improved by increased calcium consumption in men, but the same was not observed in women.
  4. Calcium and vitamin D consumption during weight-loss intervention enhanced the beneficial effect of body weight loss on the lipid and lipoprotein profile in overweight or obese women with usual low daily calcium intake.
  5. Results showed that among 1,306 young adult male and female blacks and whites aged 19 to 38, eating higher amounts of calcium-rich foods—including low-fat dairy foods—was inversely associated with abdominal fat for young white males only.

According to a recent USDA survey, average calcium intake by women aged 20 and older was only 771 milligrams per day, and the intake by men aged 50 and older was less than 866 milligrams per day.   Clearly, as compared to the U.S. Recommended Daily Allowance (“RDA”), many Americans are not getting adequate calcium intake through diet alone or with supplements. 

Over 33% of the U.S. adult population is obese, and the statistics are worsening.  While appetite, exercise, heredity, food availability, social setting and other factors influence body weight, improving calcium intake through diet or supplementation is a strategy to consider.  For the average American woman, an improvement of 200 – 500 mg of calcium per day is recommended.
