Notes: Data except for number (%) are the mean (standard error of mean). Individual group is defined as follows: normal weight and Non-Fat (Group A), BMI < 25.0 kg/m2 for women and men, and BFP < 32% for women and < 25% for men; overweight and Non-Fat (Group B), BMI ≥25.0 kg/m² and BFP < 32% for women and < 25% for men; normal weight and Fat (Group C), BMI < 25.0 kg/m2 and BFP ≥ 32% for women and ≥ 25% for men; and overweight and FAT (Group D), BMI ≥25.0 kg/m2 and BFP ≥32% for women and ≥ 25% for men. According to the IDF definition, metabolic syndrome is existing if at least 3 of the following criteria are met: WC > 102 cm (men) or > 88 cm (women), fasting glucose > 1 mmol/l, triglycerides < 1.5 mmol/l (150 mg/dl), high-density lipoprotein cholesterol (HDL-C) < 0.4 mmol/l(40 mg/dl) (men) or < 0.5 mmol/l(50 mg/dl) (women), blood pressure > 130/85 mmHg (13/8 CmHg), or treatment for previously recognized hypertension. Metabolic syndrome is defined using the NCEP ATP III criteria modified for Asian population
