Overweight people commonly have lower vitamin D levels, but whether or not low vitamin D leads to weight gain has not been well studied. A new report however suggests vitamin D may play a role.
Studying a group of some four and a half thousand older age women researchers found that those with adequate vitamin D levels were less likely to gain weight over a 4.5-year period suggesting, as the investigators put it, “low vitamin D status may predispose to fat accumulation.”
This finding was echoed in an another report published this year when a group of healthy premenopausal overweight and obese women taking 1000IU of D3 for 12 weeks experienced a significant reduction in fat mass (-2.7 kg vs. 0.4 in the placebo group).
Of course it is possible that people taking vitamin D simply feel better and become more active but if there is a weight loss effect of vitamin D it certainly deserves further investigation. In any case, if your vitamin D levels are low you would benefit from treating vitamin D deficiency.
