The Effect of Randomized Calcium Intervention Through Dairy Foods and Supplements on Body Weight and Fat Loss

Obesity is a pressing public health concern among Jordanian women. This study investigated the impact of calcium intervention on body weight and fat mass in 122 healthy women (20–45 years). In this randomized controlled trial, participants with normal weight or obesity were randomly assigned into a dairy group, a supplemental calcium group, or a control group. Anthropometric measurements were collected at baseline and after 12 weeks of intervention. Both interventions (dairy and calcium supplementation) resulted in significant weight loss and body mass index reduction. Notably, body fat percentage decreased following the intervention in normal weight and obese subgroups, with dairy products showing a stronger effect. Calcium intervention, especially through dairy consumption, effectively contributed to body weight and fat reduction in this sample of Jordanian women.
