BMR1649kcal/day
Mifflin–St Jeor resting energy.
Maintenance (TDEE)2556kcal/day
BMR × your activity factor.
Mifflin–St Jeor equation with a standard activity multiplier — an educational estimate, not a prescription. Needs vary; consult a professional for tailored advice.
The formula
Mifflin–St Jeor
BMR = 10·kg + 6.25·cm − 5·age + s (male +5 / female −161); TDEE = BMR × activity
Source: Mifflin et al. (1990)
What it means
- BMR is what you burn at rest; TDEE is a full-day estimate.
- A sensible starting point for planning energy intake.
Limitations
- Population equation — real needs vary with body composition and NEAT.
- Educational only; see a professional for tailored nutrition advice.
Educational only
This calculator gives general, educational estimates about training and physiology — not personal, medical or nutritional advice. Numbers vary between individuals; check with a qualified coach or healthcare professional before acting on them.
