To investigate the interaction of medium‐chain triglycerides (MCT) with other nutritional ingredients on postprandial energy expenditure (PPEE), 4 different commercially available meal replacement shakes were compared in a randomized, double‐blind clinical trial. Major differences from 1 serving of Product A, B, C and D were: MCT content, 5.5, 2.2, 0.4 and 0.2%; dietary fiber content, 5, 5, 3 and 0 g; and energy content, 158, 90, 90 and 200 kcal, respectively. These were individually mixed with water and taken orally following an overnight fast. Samples were randomly tested multiple times in the morning at weekly intervals. PPEE was measured by breath oxygen volume immediately before (baseline), 1, 2 and 4 h after sample intake. There was a significant rise in PPEE over baseline following consumption of product A (6.2±0.6 SEM %) during the 4 h testing period (P<0.05). This rise in PPEE was greater than that observed after consumption of products B, C, and D, which were 1.7±0.4, 1.6±0.4 and 3.7±0.5%, respectively (P<0.05). PPEE after intake of Products B, C and D had returned to the baseline level by the 4‐h measurement point. Although PPEE is usually dependent upon the caloric load consumed, PPEE per energy content in Product A was 0.59±0.06, which was about twice that of the other test diets. These results suggest that a combination of nutrients, including MCT and dietary fiber, may enhance meal‐induced energy expenditure.
