Overall, the present research suggests that eating a standard portion of ice cream (150 g, 10% of fat) containing different fat ratios of MCTs and LCTs can modestly affect fat intake and snack selection at subsequent ad-libitum eating occasions. High concentrations of MCTs (saturated) manifested their effects earlier, modestly but consistently decreasing fat intake, whereas high concentrations of LCTs (unsaturated) manifested their effects later, reducing subsequent snack intake. This may be due to differences in the absorption and metabolism of these fats. To our knowledge, this is the first study to report such a bi-phasic action of triglycerides. Nevertheless, the observed differences, being slight and only observed after an acute dose, require further research utilizing repeated dosing to understand whether this may be clinically meaningful.
