Protein needs are generally assumed to be in the 1.2 to 2.0 g/kg/day range for metabolically stressed patients (AND, 2015a). A.S.P.E.N. guidelines recommend protein needs in the 1.2 to 2.0 g/kg/day range […] Read more

Metabolic Stress and Critical Illness

Starvation and metabolic stress result in deviations from normal nutrient metabolism that alters individual nutrient needs. A chronically starved patient with mild metabolic stress experiences a reduction in resting metabolic rate of somewhere between 10 to 30 percent (Heimburger 2015). This reduction in resting metabolic rate is the body’s response to lowered energy intake that […] Read more
