Lose More Weight And Gain More Vitamin D

A study that has been published in the American Journal of Clinical Nutrition concludes that overweight to obese women who lose at least fifteen percent of their body weight increase their blood levels of Vitamin D, a fat soluble vitamin vital for overall health. That year long study will seek to help understand the link between obesity and a number of other conditions and diseases including cancer, heart disease and diabetes.

The link between an increased risk of certain diseases and excess body weight has been well established but is still not completely understood. Part of the problem facing researchers is to understand how one person who is twenty pounds overweight can be at increased risk of a disease or may develop it while someone who is much heavier may not ever have such a problem. The suggestion now is that Vitamin D levels may play a role in some way.

Vitamin D, until recently, was thought of as a secondary, largely unimportant vitamin. New research studies have shown just how vitally important it actually is and how many different functions it performs in the body. In addition to helping the body to absorb calcium, Vitamin D is needed for bone health, growth and healing as well as roles in the cells and immune function. Vitamin D also helps to decrease the effects of inflammation in the body.

The study, which lasted one year is currently one of the largest study of the effects of weight and Vitamin D levels. Over 400 women who fit the study’s criteria were divided by random assignment into four groups. The women, who were all between the ages of 50 and 75, overweight to obese, sedentary and post menopausal were either asked to follow an exercise program, a diet plan, a combination of diet and exercise or were given no intervention at all to follow. The women had blood work performed to establish their baseline Vitamin D levels with 70% of them having less than optimal Vitamin D levels. Twelve percent of those women were found to be at serious risk for Vitamin D deficiency.

At the end of the study, the women who had lost between 5 and 10% of their body weight did see a small improvement in their blood levels of Vitamin D, however, the women who lost more weight, 15% of their body weight or more, nearly tripled their Vitamin D levels. In addition to the important roles that Vitamin D plays in the body, not having enough can cause a number of very serious adverse effects which can include an increased risk of kidney stones.

Vitamin D is found in some food sources, including fatty fish and enriched dairy products, however, it is most easily obtained by the body with brief exposure to the sun. It only takes ten minutes of the sun on your skin to cause skin cells to produce Vitamin D.
