BEE Harris-Benedict Calculator

BEE Harris-Benedict Calculator for Endocrinology. A difference from Mifflin is model disagreement, not evidence that one person changed metabolism. Keep measured expenditure, predicted basal expenditure and a prescribed daily intake separately labeled.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

This is the Roza-Shizgal 1984 revision: male 88.362 + 13.397W + 4.799H - 5.677A; female 447.593 + 9.247W + 3.098H - 4.330A. It is not labeled as the original 1919 coefficient set.

When to use this calculator

Check a basal-energy estimate when the clinical worksheet specifically calls for revised Harris-Benedict. Confirm the version before comparing with another calculator; similar names can conceal different coefficients.

Inputs used

  • Adult weight in kg
  • Height in cm
  • Age in years
  • Published sex coefficient

Clinical interpretation

A difference from Mifflin is model disagreement, not evidence that one person changed metabolism. Keep measured expenditure, predicted basal expenditure and a prescribed daily intake separately labeled.

Worked example

For 80 kg, 180 cm and 40 years, the male equation gives 1796.862 kcal/day, displayed as 1796.86. The female equation gives 1571.793. Rounding occurs after the calculation, not at every multiplication.

Limitations and safety notes

The equation is a historical adult prediction and can be inaccurate in illness and altered body composition. The coefficient-check source is a stroke validation study; it is not evidence that the equation is accurate in every population.

Frequently asked questions

Does this page add activity calories?

No. It returns the basal estimate alone. Daily energy requires an independently justified activity or clinical assessment.

  • Prefer original validation studies for scoring systems and prediction tools.
  • Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
  • Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
