Energy Expenditure Measured by Indirect Calorimetry in Obesity
Mika Horie et al [2] demonstrated that obese women had higher total energy expenditure (TEE), compared with normal weight. However, this increase may be due to increased basal metabolic rate (BMR) due to higher fat-free mass (FFM) and energy demand during physical activity. However, Melo et al [3] found that obese individuals are economical, the metabolic point of view. Therefore, the energy ex...
متن کاملEnergy expenditure in critically ill patients estimated by population-based equations, indirect calorimetry and CO2-based indirect calorimetry
BACKGROUND Indirect calorimetry (IC) is the reference method for measurement of energy expenditure (EE) in mechanically ventilated critically ill patients. When IC is unavailable, EE can be calculated by predictive equations or by VCO2-based calorimetry. This study compares the bias, quality and accuracy of these methods. METHODS EE was determined by IC over a 30-min period in patients from a...
متن کاملIntra-individual variability and measurement noise in estimates of energy expenditure by whole body indirect calorimetry.
1. Four men were each studied continuously over 12 d in a whole-body calorimeter. Dietary intake and daily activities were kept constant throughout the study. 2. Day-to-day coefficients of variation in energy expenditure within subjects were found to be 1.97% over 24 h, 5.93% during basal metabolic rate measurement, 2.40% overnight and 3.22% in exercise. 3. The contribution of measurement syste...
متن کاملBasal energy expenditure measured by indirect calorimetry in patients with squamous cell carcinoma of the esophagus.
BACKGROUND Determination of Basal Energy Expenditure (BEE) is essential for planning nutritional therapy in patients with esophageal cancer. AIMS The objective of this study was to determine BEE through indirect calorimetry (IC) in patients with squamous cell carcinoma of the esophagus (SCC). METHODS Cross-sectional study involving 30 patients admitted with a diagnosis of SCC who underwent ...
متن کاملGenetic influences on human energy expenditure and substrate utilization.
Understanding the genetic factors of obesity requires consideration of the genetic basis of the underlying etiological factors including energy expenditure and substrate utilization. Genetic susceptibility studies suggest that altered energy expenditure and/or preferential substrate utilization are likely to be involved in the etiology of obesity. Twin and family studies suggest that there is a...
