Abstract
The traditional Japanese diet is known for its appropriate nutrition thanks to its balance of rice, soup, and main and side dishes and low fat content. Few reports have been made, however, on its actual health effects. We studied the effects of a low-fat, low-calorie Japanese diet on body fat, metabolic syndrome indices, energy metabolism, and sympathetic nervous system (SNS) parameters using power spectral analysis of heart rate variability.<br>Subjects were 11 young lean women with excessive body fat (21.7±0.5 yrs; BMI, 21.0±0.5 kg/m2; body fat, 29.8±0.7%) who were administered a Japanese diet of 20% fat, 60% carbohydrates, and 20% protein at 400 kcal per meal prepared in our laboratory three times a day for 2 weeks. Physical activity was maintained for the experimental period. Body weight, body fat, waist circumference, blood pressure, blood biochemical markers, resting metabolic rate, insulin resistance (HOMA-IR), and SNS activity were measured at baseline and 2 weeks. Results showed significant improvement (p<0.001) in body weight (-2.3±0.2 kg), body fat (-1.7±0.2 kg), and waist circumference (-3.7±0.6 cm). Fasting glucose, glycoalbumin, and HOMA-IR decreased significantly. Fat oxidation and SNS activity increased significantly (p<0.05), and serum triglyceride decreased, significantly (p<0.01), suggesting increased overall lipid metabolism. In conclusion, despite short-term, modest energy restriction, a low-fat, low-calorie Japanese diet contributes significantly decreasing body fat and waist circumference and improving insulin resistance, and enhances overall lipid metabolism. Our results suggest that appropriate nutritional intervention is useful in regaining desired body composition among young women with excessive fat, thus possibly preventing future metabolic syndrome.
