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

Recall that this is simply the basal, i.e., minimum daily needs. Activity will increase this substantially.

reasons

next_advice

Note: stress, activity, illness, trauma, burns, cancers can increase daily caloric requirement.
