The Calorie Requirement Conundrum
نویسنده
چکیده
Severe overfeeding of critically ill patients results in increased complications without clinical benefits. However, the optimal timing and amount of nutrition to feed critically ill adults has not been established. There are multiple prediction equations for estimating calorie expenditure of critically ill patients, but most studies comparing the accuracy of different prediction equations are inadequate. There is a wide day to day variability of the energy expenditure of critically ill patients, which means that a single indirect calorimetry study does not reflect average calorie expenditure more accurately than prediction equations in the first weeks of critical illness. Although guidelines often promote more complex means of estimating calorie expenditure, critically ill patients receive variable and often incomplete amounts of nutrition that mitigates any possible difference in the accuracy between the smorgasbord of calorie prediction equations.

متن کاملRequirement of NAD and SIR2 for life-span extension by calorie restriction in Saccharomyces cerevisiae.
Calorie restriction extends life-span in a wide variety of organisms. Although it has been suggested that calorie restriction may work by reducing the levels of reactive oxygen species produced during respiration, the mechanism by which this regimen slows aging is uncertain. Here, we mimicked calorie restriction in yeast by physiological or genetic means and showed a substantial extension in li...
متن کاملThe Fast-Casual Conundrum: Fast-Casual Restaurant Entrées Are Higher in Calories than Fast Food.
