results suggest that hyperproteic hypocaloric enteral nutrition is associated with reduced risk of multiple organ failure. The loss of lean body mass during acute illness is well-known and has been associated with poor clinical outcome
As a result of increased protein degradation and decreased muscle protein synthesis, which leads to increased nitrogen excretion so,The objectives of nutritional support therapy are to overcome the acute catabolic phase, and to ameliorate the loss of body nitrogen, preserving rather than increasing the lean body mass.
No precise method in clinical practice is available to determine the maximum acceptable loss of lean body mass
In our usual practice, we estimate macronutrients using percentages of the total caloric amount, but in the critically ill patient population this approach is not appropriate. There is still controversy regarding the accurate nutritional therapy for critically ill patients, specially the amount of calories and the types of nutrients required
