New research links Vitamin D to weight loss success:
By Tanya Wilson
The results of a new study, presented at The Endocrine Society’s annual meeting June 11, showed that pre-diet blood levels of vitamin D predicted weight loss success for individuals on a low calorie diet. They found that dieters with low levels of vitamin D simply don’t lose as much weight, including abdominal fat, as those with higher levels.
Summary of Study:
Thirty-eight overweight men and women participated. Their blood levels of vitamin D and fat distribution were measured and compared. All were on a low calorie diet, 750 calories less than their daily requirements, which lasted 11 weeks.
They found that pre-diet vitamin D levels predicted weight loss in a linear relationship, that is, as vitamin D levels rose so did the amount of weight participants lost. They also noted that higher pre-diet vitamin D levels predicted a greater loss of abdominal fat. The study was funded by the National Institutes of Health, the University of Minnesota, and the Pennock Family Endowment at the University of Minnesota. (So it wasn’t funded by the dairy industry or a supplement company, Yay
Vitamin D deficiency is already associated with obesity and diabetes, but how the connection works is still poorly understood. What makes this study special is that it’s the first time that blood levels of this nutrient were measured before starting a diet and compared to actual weight loss in dieters. Of course, more studies need to be done to find exactly what role vitamin D supplements will have, what effects different dosages and preparations may have, if they’ll work at all, and so on and so forth…
Here is another post with more information on Incorporating Vitamin D Into A Healthy Weight Loss Plan. It also discusses vitamin D’s connection to obesity and diabetes, among other things.
