A method reduces postprandial glucose from a meal. The method includes orally administering to an individual a composition containing medium chain triglycerides (MCT) and then subsequently orally administering the meal to the individual after the oral administration of the composition containing the MCTs and within about one hour of the oral administration of the composition containing the MCTs. For example, the meal can be administered about thirty minutes after the administration of the composition containing the MCTs. The postprandial glucose is reduced relative to postprandial glucose from (i) postprandial glucose from administration of an identically formulated composition containing MCTs at approximately the same time as the administration of the meal and (ii) postprandial glucose from administration of the meal without any MCTs within about one hour before or within about one hour afterward. The composition containing the MCTs can be a liquid oral nutritional supplement (ONS) providing incomplete nutrition.
