Suggested energy requirements for hospitalized patients based on body mass index

Body mass index (kg/m^2)			Energy Requirements (kcal/kg/day)
	< 15	35 – 40
	15 – 19	30 – 35
	20 - 24	20 – 25
	25 – 29	15 - 20
	> 30	< 15

The lower range within each category should be considered in critically ill patients, unless they are

depleted in body fat, to decrease the risk of hyperglycemia and infection associated with overfeeding.

Recommended daily protein intake in adults.

Clinical condition	Protein requirements (g/kg IBW* per day)
Normal Metabolic “stress (illness/injury)” Acute renal failure (undialyzed) Hemodialysis Peritoneal dialysis		0.8 1.0 – 1.5 0.8 – 1.0 1.2 – 1.4 1.3 – 1.5

*IBW=ideal body weight

Additional protein intake may be needed to compensate for excess protein loss in certain patient

groups, such as those with burn injury, open wounds, and protein losing enteropathy or

nephropathy. Lower protein intake may be necessary in patients with chronic renal insufficiency

who are not being treated with dialysis and patients with hepatic encephalopathy.
