Brief Summary
The aim of this double blind clinical trial study is to investigate whether alphacalcidol treatment in obese subjects can affect the resting metabolic rate. Moreover, the investigators will evaluate the pathways of Nesfatin-1, Peroxisome proliferator-activated receptor gamma (PPARγ) and eroxisome proliferator-activated receptor- coactivator-1 α (PGC1α) protein which may lead to change in metabic rate following treatment with either alphacalcidol or placebo.
