Subjects (average age 38 years, average BMI 29.8 kg/m2) received either 1000 IU (25 mcg) daily vitamin D3 or placebo for 12 weeks. Body weight, height, waist, hip, fat mass, vitamin D, iPTH, and dietary intakes were measured at baseline and post-intervention.
Results found the vitamin D group had increases in vitamin D levels, decreases in iPTH concentrations, and decreases in body fat mass compared to the placebo group. No change for weight or waist circumference in either group.
Findings indicate a reverse correlation between changes in vitamin D concentrations and body fat mass among healthy overweight and obese women.
Subscribers may remember me covering a similar study earlier in the year. Just to let you know, it's the same study, with the difference being that the two publications measured (and reported) different clinial parameters. Either way, I'm taking lots of D3, especially as the winter creeps closer, which probably explains my amazing physique. ;D
