Basal metabolic rate (BMR): Rate of energy expenditure after an overnight fast, resting comfortably, supine, awake, and motionless

in a thermoneutral environment.

 Basal energy expenditure (BEE): BMR over 24 hours.

 Thermic effect of food (TEF): Increase in energy expenditure elicited by food consumption.

 Energy deposition: Energy requirement for

growth.

 Total energy expenditure (TEE): Sum of BEE,

TEF, physical activity, thermoregulation, and the energy expended in depositing new tissues

and/or in producing milk.

Physical activity level (PAL): Ratio of total to basal daily energy expenditure (TEE/BEE)

Describes and accounts for physical activity habits.

 Physical activity coefficient (PA): The physical activity coefficient that correlates with PAL can be used to calculate estimated energy

requirements (EER).

 EER: Dietary energy intake that is predicted

to maintain energy balance in a healthy

individual In children, it includes the needs associated with growth For most healthy

infants and children, the equations here can

be used to determine energy needs.

For infants, children, and adolescents, EER (kcal/day) = TEE + energy deposition.

 For most hospitalized patients, it can be assumed PAL = sedentary, PA = 1.

 1 g Protéin cho 4 kcal

 + 1 g Glucid cho 4 kcal

 + 1g lipid cho 9 kcal

 G:P:L = 60% - 13% - 27%

 Theo công th c Holliday-Segar:ứ

 ≤ 10 kg : 100 kcal /kg

 >10 –20 kg : 1000kcal + 50 kcal /kg

 > 20 kg : 1500 kcal + 20 kcal /kg
