This study was performed to investigate the difference between obese and non-obese male students. To conduct this study, anthropometric measurements, blood pressure, serum lipids and insulin concentration, and daily nutrients intake of obese and non-obese mal students were measured. The results are as follows : The anthrometric measurements of the two groups showed significant difference in weight (P<0.01), waist(P<0.001), hip(p<0.0001) and thigh (P<0.001) circumference, % of body fat(p<0.0001), kg of body fat(p<0.001) and LBM (lean body mass, p<0.0001). On the other hand, the blood pressure, serum lipids and insulin, and daily nutrients intake of the two groups showed no significant difference. The WHR showed positive correlation with weight, BMI, waist circumference, % of body fat and kg of body fat in obese group. It is also founded that waist circumference, % of body fat, kg of body fat, serum triglyceride, energy and carbohydrate intake in non-obese group showed positive correlation with WHR.
