Basal Metabolic Rate (BMR)
The calories your body burns at rest. The Mifflin–St Jeor equation is the most accurate formula for most adults and the one VivMetric uses.
Formula
Mifflin–St Jeor: Men: 10·weight(kg) + 6.25·height(cm) − 5·age + 5 · Women: 10·weight(kg) + 6.25·height(cm) − 5·age − 161
Healthy range
Roughly 1,400–1,900 kcal/day for most adults, varying with size, sex, age, and muscle mass.
Military & first-responder angle
A basic nutrition input for service members in the ABCP or trying to meet body-composition standards — knowing your BMR anchors a realistic deficit (3–8 lbs/month is the Army standard).
