We compared three independent techniques for measurement of total energy expenditure (TEE) in human subjects: 1) weight-maintaining energy intake (dietTEE), 2) 24-h chamber calorimetry (chamberTEE), and 3) differential elimination rates 2H2O and H(2)18O (isotopeTEE). Twenty-three healthy adult in-patients [19 never obese (NO), 2 obese (OB), and 2 formerly-obese (RO); 9 female, 14 malel] ingested a liquid formula diet (40% of calories as fat, 45% carbohydrate, 15% protein), the volume of which was adjusted until body weight was stable for at least 14 days. Body composition was then determined by hydrodensitometry, isotope dilution, and dual photon beam absorptiometry (DXA). The thermic effect of feeding (TEF) and resting energy expenditure [REE; measured before arising (dietREE) and after arising (chamberREE)] were determined by indirect calorimetry. Non-resting energy expenditure (NREE) was calculated as NREE = TEE - (REE + TEF). Subjects then gained or lost 10% of their body weight and were restudied as described above. All measures of TEE were significantly correlated (dietTEE vs. chamberTEE r2 = 0.75; dietTEE vs. isotopeTEE r2 = 0.88; isotopeTEE vs. chamberTEE r2 = 0.73; P < 0.0001). ChamberTEE (mean +/- SE = 2,107 +/- 64 kcal/day) was approximately 20% lower than either dietTEE (2,536 +/- 94 kcal/day, P < 0.0001) or isotopeTEE (2,564 +/- 83 kcal/day, P < 0.0001). When data were normalized to metabolic mass, weight gain of 10% was associated with significant increases in dietTEE (P < 0.005) and isotopeTEE (P < 0.05) but not chamberTEE; weight loss of 10% was associated with significant reductions in dietTEE (P < 0.005) and isotopeTEE (P < 0.05) but not chamberTEE. We conclude that measures of energy expenditure obtained in a highly controlled environment by caloric titration (dietTEE) or differential excretion rates of 2H2O and H(2)18O (isotopeTEE) are not significantly different and that measurements of TEE obtained in a respiratory chamber (chamberTEE) are significantly lower than dietTEE or isotopeTEE, probably largely due to limitations on physical activity in the chamber.

Objective:The objective of this study was to describe changes in the resting energy expenditure, substrate oxidation rate, and body composition in morbidly obese women subjected to short-term caloric restriction. Methods:This was a prospective study that included ten obese women with body mass index greater than 40 kg/m2 and aged between 20-50 years. The participants were hospitalized for eight days and received a controlled conventional low-calorie diet, 1200 kcal/day, for seven days. Body weight, body mass index, abdominal circumference, body composition, resting energy expenditure, and substrate oxidation rate were evaluated at the beginning and at the end of the study. Results:A significant reduction in body weight (p=0.005), body mass index (p=0.005), abdominal circumference (p=0.005), fat mass (p=0.005) and fat-free mass (p=0.008) was observed at the end of the study. There was an average reduction in resting energy expenditure of approximately 124 kcal/day (5%). Substrate oxidation rate did not show statistically significant changes. There was a positive correlation only between body weight reduction and fat-free mass reduction (r=0.753; p=0.012). Conclusion:There was an adaptive response of the resting energy expenditure with short-term energy restriction in morbidly obese women with a 5% reduction in resting energy expenditure and a positive correlation between weight loss and the fat-free mass, which indicates the influence of fat-free mass on the decrease in resting energy expenditure. Therefore, short-term caloric restriction in morbidly obese women led to a decrease in resting energy expenditure and fat-free mass, which suggests a rapid adaptation of energy expenditure.

Objective: Hypermetabolism based on measurements of resting energy expenditure (REE) is suggested to be a potential biomarker for predicting the clinical outcomes of some diseases. We aimed to evaluate the potential value of hypermetabolism for predicting the short-term (28-day) mortality of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). Methods: A total of 105 HBV-ACLF patients, 30 chronic hepatitis B (CHB) patients and 30 healthy controls (HCs) were included in this study. The REE was measured using indirect calorimetry in the morning after 8–10 h of fasting. The predicted REE (REEHB) was determined using Harris-Benedict equation. Persistent hypermetabolism was defined as the REE:REEHB ratio > 1.20 at day 1 and day 7 after admission. The severity of liver disease was estimated using the Model for End-Stage Liver Disease (MELD). Clinical and biochemical variables were determined using blood samples ordered upon admission. These variables were compared between nonsurviving and surviving patients who were classified according to the 28-day mortality. Results: The frequency of hypermetabolism at baseline was significantly higher in ACLF patients than that in HCs and CHB patients. Forty-six (43.8%) ACLF patients died within follow-up of 28 days. Persistent hypermetabolism (OR 2.10; 95% CI 1.15–3.69; p = 0.002) and MELD score (OR 1.93; 95% CI 1.47–3.51; p = 0.012) were independent predictive indicators of 28-day mortality. Furthermore, the performance of the 2 variables (persistent hypermetabolism and MELD) together with the area under the receiver operating curve (AUROC: 0.819) was significantly better than that of MELD alone ­(AUROC: 0.694) for prediction of short-term mortality (p = 0.014). Conclusion: These findings indicate that persistent hypermetabolism is predictive of short-term mortality in this small population.
