About this calculator
BMR is the energy your body uses at rest. This calculator uses the Mifflin-St Jeor equation: 10 × weight + 6.25 × height − 5 × age, then +5 for men or −161 for women. Multiplying by your activity level gives the calories needed to maintain weight.
Results are estimates for information only. Please confirm important decisions with a qualified professional.
