Abstract

Careau et al. (5) recently published a paper entitled Energy compensation and adiposity in humans in the journal Current Biology. They evaluated measurements of total energy expenditure (TEE), basal energy expenditure (BEE) and activity energy expenditure (AEE) saved in a large data collection. Based on an overall negative correlation between BEE and AEE in a large group of subjects varying in sex, age and body mass they suggest that intense physical activity generally reduces BEE. There was controlling for sex, age, and body composition. But surprisingly the authors do not present values per kg body mass despite comparing subjects with a large variation in this quantity. Data published in former publications by one of the coauthors allow calculating daily kcal/kg from means. This indicates that low BEE accompanied by high AEE was caused by a smaller body mass in physically active subjects.Key Words: Sports, Physical Training, Nutrition, Body Mass, Weight Reduction, Circadian Rhythm
