Resting energy expenditure-fat-free mass relationship: new insights provided by body composition modeling.

摘要: The relationship between resting energy expenditure (REE) and metabolically active fat-free mass (FFM) is a cornerstone in the study of physiological aspects body weight regulation human requirements. Important questions, however, remain unanswered regarding observed linear REE-FFM association adult humans. This led us to develop series REE-body composition models that provide insights into widely used simple prediction model derived experimentally new suggest mammals as whole curvilinear, segment this function within FFM range characteristic humans can be fit with equation almost identical from composite review earlier studies, exhibit decrease proportion high metabolic rate organs greater FFM. present thus provides approach for examining relationships, advances quantitative manner previously albeit incompletely formulated associations, identifies areas need additional research.
