PORTLAND – A Portland endocrinologist led a study that linked lack of Vitamin D to weight gain.

The study involved researchers from Portland and three other cities. Doctor Erin LeBlanc from Kaiser Permanente’s Center for Health and Research said her group tracked the Vitamin D levels of more than 4,600 women through blood tests.

Doctors also tracked weight changes in all the women tested. They found that of the thousands involved in the study, 571 women gained weight. The women with low Vitamin D levels gained about two pounds more than those with healthy levels of the vitamin in their system.

Doctor LeBlanc explained that fat cells and Vitamin D have a unique relationship.

“There are actually receptors for Vitamin D on the fat cell, which would suggest that Vitamin D might be regulating that. If you take fat cells and add Vitamin D, you can see changes within the fat cell that would suggest that perhaps in the body, Vitamin D could be regulating fat break down and fat build-up," she said.

The main reason people suffer from Vitamin D deficiency, is from lack of sunshine.
