Obesity is associated with vitamin D deficiency.  The reason is that the vitamin D is trapped within the fat and cannot easily exit.  As a result, obese patients need at least twice as much vitamin D as a normal weighted individual in order to maintain a normal vitamin D status with a 25(OH)D between 30-60 ng/ml.
