Background: This study is to investigate consequent nutrient intake status, influences of body mass index (BMI) and serum lipid composition, and fat distribution on the low-molecule peptide, green tea leaves and dietary fiber supplementation, SG-30 diet program.
Methods: During 2 months of this research (April to May, 2002), 47 women aged 20yr-30yr (average age 26.2yr) were selected as subjects. Nutrient intake was investigated by questionnaire and 24-hr recall method. Antropometric assessments of the subjects were investigated by SBIA method (Segmental bioimpedance assay, Inbody 3.0).
Results: Mean body weight was 60.7kg, mean body height 161.7cm and mean BMI 23.4. Status of energy intakes significantly decreased (p<0.01) and dietary fiber intakes significantly increased (p<0.00l) after SG-30 diet supplementation. BMI and WHR (waist-hip ratio) significantly decreased (p<0.01) and body fat significantly decreased after SG-30 diet supplementation (P<0.00l). Total cholesterol and LDL-cholesterol significantly decreased after SG-30 diet supplementation (P<0.05). HDL-cholesterol was negatively correlated with BMI and WHR(p<0.0l). LDL/HDL ratio was positively correlated with BMI (p<0.01) and WHR (p<0.05).
Conclusion: Above results of this study show that low-molecule peptide, green tea leaves and dietary fiber supplementation, SG-30 diet progran-added routine diet improves body fat distribution, total cholesterol, LDL-cholesterol. Especially, decrease of abdominal fat and WHR were notable. That meant decrease of risk factors.
