The formula
Mifflin-St Jeor is considered the most accurate BMR formula for most adults. Multiply BMR by activity factor for TDEE.
BMR (M) = 10×weight + 6.25×height − 5×age + 5
Worked example
- Male, 30 yrs, 75 kg, 178 cm, moderate activity
- BMR ≈ 1,738 kcal
- TDEE ≈ 2,694 kcal
Result: 2,694 kcal/day
