Primary Outcome Measures :
  1. Change in Muscle insulin sensitivity [ Time Frame: before and after at least 16 weeks of treatment ]
    The outcome will be assessed during hyperinsulinemic-euglycemic clamp procedure in conjunction with stable isotopic tracer infusion before and after intervention period.


Secondary Outcome Measures :
  1. Changes in glucose tolerance [ Time Frame: before and after at least 16 weeks of treatment ]
    The outcome will be assessed during modified oral glucose tolerance test
