测定了8名受试者进食735千卡后的静息代谢率(RMR)的变化。与管饲(TF)相比，套饲(MF)的RMR增加幅度更大。呼吸商(RQ)的测量表明，MF的RMR增加与葡萄糖氧化增加有关，而TF的RMR增加可能主要是由于能量储存的成本。血浆去甲肾上腺素(NE)的测定表明，交感神经系统可被MF激活，但不能被TF激活。血糖和胰岛素测定表明，在食物摄取过程中，胰岛素的分泌增加，但只有在MF的情况下。因此，在开始进餐后的30分钟内，观察到葡萄糖氧化增加，这可能与NE和胰岛素分泌增加有关；这种影响在TF情况下是不存在的。这些结果并不证实食物的特定动态作用的概念，并表明，与摄入的营养成分无关，餐后RMR的增加也受到感觉和认知刺激的影响。
The postprandial changes in resting metabolic rate (RMR) were measured in 8 subjects after the ingestion of 735 kcal taken in the form of a meal or fed by stomach tube. A much larger increase in RMR was found with meal feeding (MF) as compared with tube feeding (TF). Measurements of respiratory quotient (RQ) indicated that the increase in RMR with MF is related to increased glucose oxidation, whereas with TF it is possibly explained primarily by the cost of energy storing. Determination of plasma norepinephrine (NE) indicated that the sympathetic nervous system is activated by MF but not by TF. Plasma glucose and insulin determinations have shown that the secretion of insulin is increased during food ingestion but only with the MF situation. Thus, in the 30 min after the beginning of the meal, an increased glucose oxidation was observed that is possibly related to an enhanced NE and insulin secretion; such effects were nonexistent in the TF situation. These results do not substantiate the notion of the specific dynamic action of food and indicate that independent of the composition of the ingested nutrients, the postprandial increase in RMR is also influenced by sensory and cognitive stimulations.
