Vitamin D and Weight Loss

We’ve known for a few years that vitamin D and weight are linked, but the debate has been how. People who are overweight or obese tend to have low vitamin D levels. What came first? The obesity or the vitamin D loss?

A new study from the University of Minnesota and presented at the Endocrine Society’s 91st Annual Meeting measured vitamin D levels in 38 men and women before putting them on a calorie-restricted diet. Bottom line—the higher the pre-diet vitamin D levels, the greater the weight loss, particularly weight around the middle, which is notoriously hard to lose and is associated with insulin resistance. The researchers suggest that adding a vitamin D supplement to a diet plan could enhance weight loss.

Other researchers theorize that vitamin D deficiency contributes to insulin resistance, one of the primary causes of weight gain.

Taking a vitamin D supplement without changing eating habits will probably not magically make the fat melt away. A 2008 study done in Norway simply gave vitamin D or a placebo to 334 overweight people and found no significant weight loss difference in the vitamin D group at the end of 12 months.

Vitamin D has become a nutritional darling in the past few years, and for good reason. A deficiency has been strongly linked to osteoporosis, many types of cancer, depression and other mood disorders, diabetes, heart disease and poor immune function.
