Calculates daily energy expenditure.
Formula
Note: The Basal Energy Expenditure must be multiplied by activity and stress factors to calculate total caloric requirement. BEE, kcal/day (male) = 66.5 + (13.75 × weight, kg) + (5.003 × height, cm) - (6.775 × age) BEE, kcal/day (female) = 655.1 + (9.563 × weight, kg) + (1.850 × height, cm) - (4.676 × age) Harris-Benedict adjustment: Sedentary (little to no exercise) = BEE × 1.2 Light exercise (1-3 days per week) = BEE × 1.375 Moderate exercise (3–5 days per week) = BEE × 1.55 Heavy exercise (6–7 days per week) = BEE × 1.725 Very heavy exercise (twice per day, extra heavy workouts) = BEE × 1.9
Pearls / Pitfalls
Recall that this is simply the basal, i.e., minimum daily needs. Activity will increase this substantially.
Advice
Note: stress, activity, illness, trauma, burns, cancers can increase daily caloric requirement.
