BEE Calculator
Estimate Basal Energy Expenditure (BEE) — the calories your body burns at complete rest — using the revised Harris-Benedict equation. It also estimates Total Energy Expenditure (TEE) for hospitalised patients by applying stress factors for minor, moderate and severe illness. Enter sex, age, weight and height to get the figures.
Formula
Male BEE: 88.362 + 13.397×W + 4.799×H − 5.677×A
Female BEE: 447.593 + 9.247×W + 3.098×H − 4.330×A
TEE = BEE × stress factor
- BEE (Basal Energy Expenditure) is the calories burned at complete rest, here from the revised Harris-Benedict equation (Roza & Shizgal, 1984).
- Male: BEE = 88.362 + 13.397×weight(kg) + 4.799×height(cm) − 5.677×age.
- Female: BEE = 447.593 + 9.247×weight(kg) + 3.098×height(cm) − 4.330×age.
- Total Energy Expenditure (TEE) multiplies BEE by a stress factor: about 1.2 for minor illness, 1.4 for moderate, 1.6 for severe.
- BEE is essentially the clinical term for BMR; the stress factors estimate higher needs during illness or recovery.
- These are screening estimates — individual energy needs vary and clinical nutrition should be guided by a professional.

Inputs
- Sex: male
- Age: 35 years
- Weight: 70 kg
- Height: 170 cm
BEE = 88.362 + 13.397×70 + 4.799×170 − 5.677×35 ≈ 1666 kcal/day. With a minor-illness factor of 1.2, TEE ≈ 1999 kcal/day.
Frequently asked questions
What is Basal Energy Expenditure?
It's the number of calories your body uses at complete rest to maintain vital functions — essentially the clinical term for basal metabolic rate (BMR).
What is the difference between BEE and TEE?
BEE is your resting requirement. TEE (Total Energy Expenditure) multiplies BEE by a stress factor to account for the extra energy needed during illness, injury or recovery.
Which stress factor should I use?
Roughly 1.2 for minor illness, 1.4 for moderate, and 1.6 for severe illness or major surgery. Clinicians choose the factor based on the patient's condition.
Is this a substitute for clinical assessment?
No. It provides an estimate using a standard equation. Actual nutrition planning for patients should be done by a qualified dietitian or physician.
