Energy expenditure: components and evaluation methods.

Abstract

Introducción: Determinar el gasto energético (GE), considerando la actividad física y el estado de salud, es muy importante para ajustar el cálculo de la necesidad nutricional para cada individuo. Para eso, se pueden utilizar técnicas como la calorimetría indirecta, la bioimpedancia eléctrica, el agua doblemente marcada, las ecuaciones predictivas, entre otras. Estos métodos son utilizados en la práctica clínica y en estudios científicos. Sin embargo, debido a la inconsistencia de los resultados de estas investigaciones, todavía no hay un consenso respecto a su aplicabilidad. Objetivos: De esa forma, esta revisión tiene como objetivo discutir los componentes del gasto energético, así como las técnicas para su determinación y estimativa, señalando sus ventajas y limitaciones. Resultados y discusión: La calorimetría indirecta y el agua doblemente marcada son métodos considerados más acurados, sin embargo onerosos. Los otros métodos presentan limitaciones, pero por su practicidad y bajo coste, algunos de ellos pueden ser usados con cautela.

Introduction: The determination of energy expenditure, considering the physical activity level and health status, is very important to adjust the individuals' nutritional supply. Energy expenditure can be determined by using indirect calorimetry, bioelectrical impedance, doubly labeled water, predictive equations, among others. All these methods have been used in clinical and research areas. However, considering the inconsistence in several research results, there is no consensus yet about the applicability of many of these methods. Objectives: The aim of this review is to describe the components of energy expenditure and the methods for its determination and estimation, summarizing their main advantages and limitations. Results and discussion: Indirect calorimetry and doubly labeled water are considered more accurate methods, but expensive. On the other hand, even though other methods present limitations, they are convenient and less expensive, and can be used with some caution.
