	Baseline	12th week	24th week	Baseline	12th week	24th week
BMI	29.74 ± 3.88	28.69 ± 3.70	28.13 ± 3.86	29.77 ± 3.27	29.17 ± 3.43	28.85 ± 3.59	0.799
WHR	0.83 ± 5.67	0.82 ± 6.03	0.81 ± 6.0	0.81 ± 4.80	0.80 ± 4.76	0.80 ± 4.73	0.247
WSR	55.49 ± 4.81	53.69 ± 4.54	52.79 ± 4.73	54.79 ± 4.93	53.25 ± 4.83	52.44 ± 4.87	0.744
HOMA-IR	23.52 ± 12.77	9.15 ± 13.37	22.12 ± 11.67	18.74 ± 13.01	14.46 ± 10.40	16.31 ± 11.39	0.516
QUICKI	1.19 ± 0.45	0.34 ± 0.91	1.32 ± 0.20	1.13 ± 0.24	0.92 ± 0.59	1.09 ± 0.46	0.396

All values are mean ± SD.

There were no significant differences between groups in 3 stages of the study (general linear model).

BMI = Body mass index; WHR = Waist to hip ratio; WSR = Waist to stature ratio; HOMA-IR = Homeostasis model assessment of insulin resistance; QUICKI = Quantitative insulin sensitivity check index
