Objectives:
Is there a causal relationship between dairy products or calcium supplements and the reduction in fat mass and BMI among overweight or obese adults?
Study design:
This review article included 10 and 14 RCTs with ≥ 12 weeks interventions of calcium supplements and dairy products among overweight (BMI>25) or obese (BMI>30) adults aged ≥18.
Results and conclusions:
The investigators found that dairy products significantly reduced fat mass among overweight or obese adults [SMD = -0.40, 95% CI = -0.77 to -0.02].
This reduction was also significant in the analysis of RCTs with low risk of bias scores.
The investigators found that dairy products significantly reduced BMI among overweight or obese adults [SMD = -0.46 kg/m2, 95% CI = -0.67 to -0.26].
This reduction was also significant in the analysis of RCTs with low risk of bias scores.
The investigators found that calcium supplements significantly reduced fat mass among overweight or obese adults [SMD = -0.15, 95% CI = -0.28 to -0.02].
However, this reduction was not significant in the analysis of RCTs with low risk of bias scores.
The investigators concluded there is a causal relationship between dairy products without distinction of fat percentage and the reduction in fat mass and BMI among overweight or obese adults.
