How is it calculated?
BMR = 10 × kg + 6.25 × cm − 5 × age + 5 (men) or − 161 (women)
The Mifflin–St Jeor equation is considered the most accurate for most adults. The revised Harris–Benedict equation usually gives a slightly higher number.

Your basal metabolic rate is the energy your body uses at complete rest to breathe, circulate blood and keep warm. It is the starting point for any calorie plan.

Common questions
Is a higher BMR better?
A higher BMR means you burn more at rest. Muscle raises it; it falls slowly with age.
Should I eat my BMR to lose weight?
Not usually — that is very low. Base your plan on your TDEE, which adds activity.
