Is it true that high dietary calcium intake promote weight loss?
High dietary calcium intake does not promote weight loss.
Although energy balance is the key element in weight regulation, several studies suggested that calcium metabolism and perhaps other components of dairy products may contribute to shifting the energy balance and thus play a role in weight regulation.Â In 1988 Metz et al.  demonstrated a reduction in body fat mass in two strains of hypertensive ratsâ€™ higher calcium intakes (in conjunction with higher sodium intake). This review discusses the effect of high dietary calcium on weight loss. Shapses et al  studied the effect of calcium supplementation in postmenopausal and premenopausal women with BMI ranging from 28-42 kg/m2. They found no significant differences in body weight or fat mass change between the placebo and the calcium-supplemented groups. Reid et al  found similar results for older women. Bowel et al  found similar results in overweight adults (male and female) with age range 25-64 yrs. Gunther et al  found similar results in young women age 18-30. Berkey et al  found similar results in a cohort study with children age 9-14 years.
