Obese adults who increase their dietary calcium while adhering to a diet lose more weight than those on a similar diet who don’t take additional calcium.
Thirty-two obese adults were placed on four different diets for six months: a balanced-deficit diet (500 mg of dietary calcium per day), a standard diet (400 to 500 mg of dietary calcium per day), a high-calcium diet (800 mg of dietary calcium per day) or a high-dairy diet (1,200 to 1,300 mg of dietary calcium per day).
Patients on the high-dairy and high-calcium diets lost the most weight. Total fat loss in the trunk region of the body was also highest in these groups.
