rest
period.
Calculate the total energy expenditure (TEE) using Mifflin-St. Jeor formula
for a patient
who is mildly obese. ( Correct answers ) 1685 kcal/day; Patient height in
inches: (5 feet
x 12 in/ft) + 4 in = 64 in. Patient's height in cm: 64 in x 2.54 cm/in =
the respective
162.56. Patient's numbers in the formula before adding height and weight
together and
weight in kg: 178 lbs / 2.2 lbs/kg = 80.91. Multiply the patient's height,
weight, and age to
