1.The diurnal variation of diet-induced thermogenesis (DIT) was measured, using healthy and normoweighty subjectsThe subjects were 6 male young men averaged 19(]SY.+-。[)1.3years. Their physical characteristics averaged 169.2(]SY.+-。[)4.7cm in height, 57.3(]SY.+-。[)5.6kg in body weight, 19.8(]SY.+-。[)1.5in BMI, 44.0(]SY.+-。[)4.1kg in LBM and 22.2(]SY.+-。[)1.9 in %FAT.Following the measurement of their basal metabolic rates, normo-nutritive liquid diet was given at 7.40 (breakfast), 11.40 (lunch), 17.40 (supper) and 23.40 (midnight meal) each and their respective 6h (8.00-, 12.00-, 18.00-and 24.00) energy expenditures were measured. For the convenience of the measurement, experiments were carried out twice-dividedly, i.e.at breakfast and supper and at lunch and midnight meal. postprandia DIT %dose was 13.9,12.8,9.8 and 8.5%, respectively after breakfast, lunch, supperand midnight meal ; DIT showed low values after supper and midnigth meal.2.The influence of chewing on DIT was measuredThe … More subjects were 10 male young men averaged 19.7 years. Tge base group was given test meal (normo-nutritive liquid diet) only, the chewing group being given test meal following chewing sugarless gum (873 rtimes : 25 subjucts' mean chewing times per meal), and their respective 6h-energy expenditures were measured. Post-prandial DIT % dose was greater for the chewing group (4.5%) than the base gruup (3.9%), up to 1.5h post-prandially, but showed no difference in terms of 6h.3.Obese subjects were determined for their post-breakfast DITThe subjects were 23 obese women aged 23-66 years and of BMI 29.7(]SY.+-。[)2.8. The normo-nutritive liquid diet was given at 7.40 a.m., and their respective 4h (8.00-) energy expenditures were measured. Because of variations of DIT observed among these obese women, H (12 subjects) and L (11 subjects) groups were defined as above and below 10%, respectively, with reference of 10%, which is said to be DIT value in general.DIT % dose prove to be 13.6 and 4.3% for H and L groups, respectively, with a significant inter-group difference (p<0.05).

1.本研究测定了6名健康男性青年的膳食诱导产热（DIT）日变化，平均19（±）SY。（）1.3年。他们的物理特征平均值为169.2（]SY. ±-.
