The purpose of this study was to observe the effects of fiber?free control diet (CD), cellulose diet (CED) and pectin diet (PTD) on diet induced thermogenesis (DIT) in healthy Korean woman for 3 hours. The three test diets were as follows: CD (carbohydrate intake: 63.4% of energy, protein intake: 14.0% of energy and fat intake: 25.8% of energy), CED (carbohydrate intake: 62.5% of energy, protein intake: 14.0% of energy and fat intake: 26.1% of energy) and PTD (carbohydrate intake: 62.7% of energy, protein intake: 14.0% of energy and fat intake: 26.2 of energy). Groups were served 10 g of cellulose for CED and 10 g of pectin for PTD, respectively. DIT was measured at fasting state and at 30, 60, 90, 120, 150 and 180 min after consuming each diet. The mean age of all subjects was 22.3±1.9 years. Body weight was 52.5±8.6 kg and body mass index was 20.6±2.7 ㎏/㎡. Preprandial resting energy expenditure was 0.79±0.02 kcal/min and postprandial DIT were 14.05±0.62% for CD, 9.33±0.62% for CED, 11.07±1.35% for PTD as a percentage of the energy load. DIT of CD was significantly higher than those of CED and PTD. There was no significant difference in postprandial change in body temperature after consuming each test diets and the sympathetic nervous system activity measured by heart rate was significantly higher in CD than CED and PTD (p＜0.05). With this study, it can be concluded that CED and PTD have significantly lowered in DIT (p＜0.05). We didn’t show the correlation of the factors that relate in DIT; thus, further experiments on that matter should be followed.
