· 14.4 - Estimating Daily Caloric Need based on RMR – Harris-Benedict Equation Flashcards
1
Q
BMR
A
Basal Metabolic Rate (BMR)
BMR measures how much energy your body uses at rest.
Conditions for Measuring BMR:
- 12–14 hours after your last meal.
- Completely at rest (but not asleep).
- Room temperature of 26–30°C.

Q
RMR
A
Resting metabolic rate (RMR) is the term used to refer to an estimate of metabolic rate under less rigorous conditions.

Q
Harris Benedict Equation
A
- Males
RMR = 66.5 + (5 x H) + (12.7 x W) - (6.8 x A) - Females
RMR = 665 + (1.9 x H) + (9.5 x W) - (4.7 x A)
In this equation, W equals a person’s weight in kilograms; H equals height in centimetres; and A equals age in years. The result can then be multiplied by an “activity factor” to arrive at one’s daily caloric need.
