Mifflin-St Jeor BMR and daily energy need.
Daily energy need
2,295 kcal
BMR 1,669 kcal × activity 1.375
What do these numbers mean?
- BMR estimates daily energy at rest. Multiplying it by the activity factor estimates maintenance energy. The ±500 figures are approximate planning estimates, not a guaranteed weight change or a medical prescription.
- In decimal numbers, commas separate thousands and a dot separates decimals: 1,234.5 = 1234 + 0.5. ×10^3 means multiply by 1000; ×10^-3 means divide by 1000. Display rounding can make tiny differences between shown totals.

How this is worked out
- Mifflin-St Jeor: 10×72 + 6.25×175 − 5×30 + 5 = 1,669 kcal.
- Multiply by the activity factor 1.375 → 2,295 kcal per day.
