再喂养策略需要能量分配的知识。根据能量平衡原理，能量摄入（Ei）在维持（Em）、活动（Ea）、生长（Eg）和粪便和尿液损失（Ew）之间进行划分。因此，能量需求可以计算为能量平衡方程（方程1）各分量之和。在合成代谢条件下，Ei等于膳食Ei需求。Ei在组织生物合成所消耗的能量（Esyn）和作为新组织储存的能量（Est）之间分配。这两个值根据体重增加的组成而变化。由于Em和Ei不能容易地分离，因此估计Em+ i的和。从参考婴儿的正常生长估计，少于15%的膳食Ei被分配到Ei，而在快速追赶生长期间，Ei可能是Ei的50%或更多。Em+和E的合理估计将能够预测在加速增重期间再喂食的能量需求。
Refeeding strategies require knowledge of energy partitioning. By principles of energy balance, energy intake (Ei) is partitioned between maintenance (Em), activity (Ea), growth (Eg) and faecal and urinary losses (Ew). Energy requirements can thus be calculated as the sum of the components of the energy-balance equation (equation 1). Under anabolic conditions, Ei is equal to dietary Ei requirements.E, is partitioned between energy expended for tissue biosynthesis (Esyn) and energy stored as new tissue (Est). Both values vary according to the composition of weight gained. Since Em and E, cannot be easily separated, the sum Em+, is estimated. From estimates of normal growth in the reference infant, less than 15% of dietary E, is partitioned to E,, whereas during rapid catch-up growth, E, may be 50% or more of Ei. Reasonable estimates of Em+, and of E, would enable prediction of energy requirements for refeeding during accelerated weight gain.
