Summary: This study investigated the impact of metabolic syndrome and its components on resting energy expenditure (REE). The findings revealed that individuals with metabolic syndrome had significantly higher REE, and the increase in the number of components was associated with a stepwise increase in REE.

Summary: Measuring resting metabolic rate is time-consuming and expensive, so equations have been developed to estimate RMR. In elderly individuals with type 2 diabetes, existing equations generally underestimate RMR. Equations developed for obesity or the elderly may be more accurate for this specific population.

Summary: A negative energy equilibrium between energy expenditure and energy intake remains crucial in obesity management. Recent findings show that energy expenditure depends on body composition and is greatly affected by weight changes, especially in weight loss. Metabolic adaptation, the difference between measured and predicted resting metabolic rate after weight loss, is influenced by differences in body composition, with loss of fat-free mass playing a significant role.

Summary: This study found that individuals with FSHD have a 15% lower absolute resting metabolic rate (RMR) compared to controls, but when normalized to lean body mass, no differences were observed. This suggests that the lower levels of lean body mass observed in FSHD patients likely contribute to the lower absolute RMR values.

Summary: The consumption of green tea catechins (GTC) may have positive effects on respiratory quotient (RQ), but the effects on resting metabolic rate (RMR) and energy expenditure (EE) are inconclusive and require further investigation to determine the adequate doses for supplementation.

Summary: The basis of medical nutrition therapy for patients with LC-FAODs is to provide adequate energy to maintain anabolism and prevent catabolism. However, it is unclear if energy expenditure among these patients is similar to the normal population. In a study of 31 subjects with LC-FAODs, their measured resting energy expenditure (REE) and total energy expenditure (TEE) were found to be lower than estimated. Comparison with normal data from NHANES and DRI further supported the conclusion that patients with LC-FAODs have lower energy expenditure than the normal population. Current prediction equations may overestimate energy expenditure for LC-FAOD patients.

Summary: Any explanation of appetite control should consider both the physiological processes that promote eating and those that inhibit it. However, it was only 15 years ago that research focused on the roles of body composition and appetite. Studies have shown a positive association between fat-free mass (FFM) and meal size and energy intake (EI), with resting metabolic rate (RMR) mediating this influence. These findings highlight the importance of considering both drive and inhibition in models of appetite control, and suggest that body composition and energy expenditure should be included as biological signals alongside traditional adipose tissue and gastrointestinal signals.

Summary: The differences in thermic effect of food (TEF) between morning and evening can be explained by the underlying circadian variability in resting metabolic rate (RMR), which is independent of the acute effect of eating.

Summary: The present study aims to assess the agreement between measured resting metabolic rate and different predictive equations, and propose new equations for estimating the rate in high-level athletes. The new equations showed good agreement and accuracy, with Cunningham's equation being the best option among the existing equations.

Summary: This paper revises the Harris-Benedict equations by developing and validating new equations for estimating resting metabolic rate (RMR) in adult subjects with different body types. The study includes 722 Caucasian subjects, excluding pregnant or lactating women and those with active infections or uncontrolled diseases. The new equations, which consider age, body weight, height, and sex, show more accurate results compared to other equations commonly used for predicting RMR.

Summary: The study found that hypertensive patients have a higher resting metabolic rate than normotensive patients, along with reduced insulin sensitivity. This increased metabolic rate can be explained by an elevated myocardial oxygen consumption due to an increased resting double product, combined with differences in body composition between hypertensive and normotensive subjects.

Summary: In this study, it was found that supraclavicular PDFF is not a determinant of resting metabolic rate (RMR), while a negative association was observed between the difference in PDFF between gluteal and supraclavicular regions and RMR. The FTO gene variant rs1421085 was not associated with RMR or PDFF in this study, highlighting the need for further research on the effect of brown adipose tissue on RMR.

Summary: Resting metabolic rate (RMR) is the key factor in determining an individual's energy requirement. This study aimed to develop a new equation for predicting RMR in healthy Sri Lankans, using indirect calorimetry. The equation developed, including weight and sex code as independent variables, was able to predict 88.5% of the variance in RMR.

Summary: This study aimed to develop and validate new resting metabolic rate (RMR) estimation models and explore their agreement with indirect calorimetry (IC) in Para-Athletes. Four novel RMR equations were proposed, which demonstrated potential for estimating energy requirements in elite Para-Athletes. The results also showed that the Harris & Benedict equation was the most consistent when compared to IC, suggesting its usability in this population.
