Outline of Final Research Achievements

The study was done in order to determine the variations in energy metabolim (expenditure), food intake, body composition　by estimating seasonal factors such as temperature and food life-style-related factors. Twenty eight female college students living in Kansai area of Japan participated in this study through a year from winter to autumn. The results showed that resting energy metabolism(REM kcal/LBM ) was significantly decreased by 20 % in summer(lowest in the seasons) than that of winter(highest). The energy intake was significantly decreased by 26% in summer　than that of winter. These results showed that there are seasonal changes in REM. We may assume that loss of body weight occurred in summer was mainly induced by decreasing body fat but not due to loss of muscle content. The higher body fat content in cold season indicates accommodation to the climate. High intake of vegetable lead to lower body fat within normal range but to a lesser extent than seasonal change.
