How This Calculator Works
BMR is the energy your body uses at complete rest to keep you alive — breathing, circulation, cell production. The Mifflin-St Jeor equation is the most accurate modern estimate.
Formula
Men: 10·kg + 6.25·cm − 5·age + 5 | Women: 10·kg + 6.25·cm − 5·age − 161
Example
A 28-year-old 65 kg, 165 cm woman has a BMR of about 1,402 cal/day.
