Data are expressed as the mean ± SE or the number (%). value by 2-sample -test or chi-square test. VFA: visceral fat area; SFA: subcutaneous fat area; DXA: dual-energy X-ray absorptiometry; ALT: alanine aminotransferase; GGT: -glutamyl transferase; CRP: C-reactive protein; LDL: low-density lipoprotein; HDL: high-density lipoprotein; TG: triglyceride; MDA: malondialdehyde. One MET is roughly equivalent to 1 kcal/min for a person weighing 60 kg. value by Mann-Whitney test.
