Women who consumed less than 1200 mg of calcium per day and who were given a 1000 mg calcium supplement per day were 11 percent less likely to gain either a small amount of weight, defined as 2-7 pounds, or more moderate weight gain, defined as greater than 7 pounds according to a study from Kaiser Permanente of Northern California. Subjects
Subjects: 36,282 women, 50-79 years-old
The study was a randomized, double-blinded, placebo-controlled study performed with 36,282 postmenopausal women, aged 50 to 79 years, who were already enrolled in the dietary modification and/or hormone therapy arms of the Women’s Health Initiative clinical trial.
Dose: 1000 mg of calcium plus 400 mg of vitamin D
The women were given either 1000 mg of calcium plus 400 mg of vitamin D per day or a placebo.
Time: Weight change after 7 years
Change in body weight was determined after 7 years.
Conclusion: Calcium slightly reduces weight gain in women with inadequate calcium intake
“Calcium plus [vitamin D] supplementation has a small effect on the prevention of weight gain, which was observed primarily in women who reported inadequate calcium intakes,” the paper concluded.
