A study published online yesterday in the Journal of Women’s Health found that women with low vitamin D status may be prone to weight gain.
The study by Erin LeBlanc, MD, an endocrinologist and researcher at the Kaiser Permanente Center for Health Research in Portland, Oregon examined vitamin D status and weight for 4,659 women over the age of 65.
When looking at vitamin D levels of women who lost or maintained weight, the researchers found no association with vitamin D status.
Among the 571 women who gained weight during the 5 year study, those with insufficient vitamin D levels (<30ng/mL) gained an average of 18.6 lbs., while women with sufficient levels gained an average of 16.4 lbs.
The researchers also found that women with insufficient levels when the study began weighed more than the women with vitamin D levels of 30 ng/mlL or above.
Of course, the authors call for more research on the topic before there can be a supplement recommendation made for weight loss purposes.
