We describe a new method of studying the thermic response to dietary fuels that involves continuous infusion of a liquid formula diet through a thin nasogastric tube. The data show that the steady inflow of dietary fuel is accompanied by a relatively constant level of energy expenditure, the magnitude of which depends on the rate of fuel inflow. An increase in the rate of fuel infusion above that required for caloric maintenance leads to a rise in energy expenditure. We also give examples, based on preliminary observations, of how the technique can be used to more precisely quantify energy metabolism. The technique may prove useful in the studying efficiency of energy utilization and in examining the extent to which individuals differ in energy efficiency.
我们描述了一种研究对膳食燃料热反应的新方法,该方法涉及通过细鼻胃管持续输注液体配方饮食。数据表明,膳食燃料的稳定流入伴随着相对恒定的能量消耗水平,其大小取决于燃料流入速率。将燃料输注速率提高到维持热量所需的速率以上会导致能量消耗增加。我们还根据初步观察结果举例说明了该技术如何用于更精确地量化能量代谢。该技术可能在研究能量利用效率以及检查个体在能量效率方面的差异程度方面证明是有用的。
