INS and Insulin resistance: The primary objective is to compare the mean changes in the serum levels of biochemical parameters (fasting plasma glucose (FPG), 2 h post-prandial (2hpp), HbA1c, serum insulin, insulin resistance (IR), insulin sensitivity (IS) %, beta cell function (BCF) %, TG, TC, LDL-C, high-density lipoprotein (HDL), very low-density lipoprotein (VLDL), total blood antioxidant capacity (TAC), malondialdehyde (MDA), serum zinc, urine zinc, serum interleukin-B (IL-1B), and high-sensitivity C-reactive protein (hs-CRP)) between the groups.
