Thirteen women aged 18-23 yrs old were divided into two groups : group one was of six women who consumed snacks ; candy, cookies, chocolate, etc., "very frequently" between meals almost everyday, group two was of seven women who seldom consumed snacks. The BMI of both groups were matched (19.7±1.0 kg/m^2 ). The DIT was measured 5h after ingestion of a meal (2220kJ=531kcal) using the Douglas bag technique. Each subject had their DIT measured on eight occasions to obtain average DIT values because DIT had large intra-individual variability. Indeed, each subject's DIT values were markedly different (the mean intra-individual CV=39.6%). There was no significant difference between the two groups in percentage of body fat, resting meta- bolic rate (RMR), or RMR/body weight. The mean value of DIT (±SD) of group one (6.4±1.2%) was lower than that of group two (7.8±0.9%) (p<0.05). Also, the main effects of the groups and the time after ingesting the test meal on postprandial energy expenditure were significant (two-way ANOVA ; p<0.001), but the interaction between the group and the time after ingesting the test meal was not significant. In conclusion, eating habits with habitual snacking blunt DIT in young women. (Jpn. J. Phys. Fitness Sports Med. 2003, 52 : 249-254)
