Most accurate for general population

Male: 10×W + 6.25×H - 5×A + 5

Female: 10×W + 6.25×H - 5×A - 161

Harris-Benedict (Revised 1984)

Original BMR formula

Male: 88.362 + 13.397W + 4.799H - 5.677A

Female: 447.593 + 9.247W + 3.098H - 4.330A

Katch-McArdle

Most accurate for athletes

BMR = 370 + (21.6 × Lean Body Mass(kg))

Cunningham (1980)

Alternative for athletic populations

BMR = 500 + (22 × Lean Body Mass(kg))

* W = Weight (kg), H = Height (cm), A = Age (years)
