High‐fat from butter and sesame oils based diet have almost same effects on post energy expenditure (PEE) and satiety in healthy adults

Abstract

The objective of this study was to compare the thermic effect of butter(SFA‐rich) and sesame oil(PUFA‐rich) based diet on PEE. Subjects were eight healthy university students aged 19–22 years. The meals were two isocaloric diet which consist of 50, 40, and 10% of fat, carbohydrate, and protein content, respectively. Energy expenditure was measured by indirect calorimetry and satiety (hunger, appetite, and prospective food consumption and fullness) was assessed by Visual Analogue Scales at preprandial and every 30 min over 5 hours after meal consumption. PEE of sesame oil diet increased more rapidly (peak at 90‐min) than butter diet (peak at 150‐min). However, PEE of butter diet decreased relatively faster after peak time. Total thermogenesis of butter(30.8 kcal/5h) was lower than that of sesame oil(34.4 kcal/5h ), but not significantly different. 6.5% of butter and 7.3% of sesame oil diet were contributed as thermic effect for those dietˈs digestion and absorption. There were no significant differences in thermic effects and satiety values between SFA rich diet and PUFA rich diet. Thus, number of double bond in fatty acid does not influence on energy expenditure.This research was supported by Basic Science Research Program, National Research Foundation of Korea funded by the Ministry of Education, Science and Technology.
