INS and Insulin resistance: A significant difference between treatment groups was observed for the following parameters: insulin levels (p = 0.003), insulin resistance (assessed by HOMA (p = 0.002) and QUIKI (p = 0.007)), leptin/adiponectin ratio (p = 0.040), RQ (p = 0.008), LDL-cholesterol levels (p = 0.031) and urinary norepinephrine levels (p < 0.001).
