ResultWhat it means?
< 1200 kcalVery low BMRBelow 1200 kcal/day is uncommon for healthy adults and may indicate a small body frame, low lean mass, or under-reporting of inputs.
1200 – 1500 kcalLow BMRBetween 1200 and 1500 kcal/day is typical for small adults and for many women — perfectly normal if your body size matches the bracket.
1500 – 2000 kcalModerate BMRBetween 1500 and 2000 kcal/day is a common resting range for average-sized adults.
2000 – 2500 kcalTypical BMRBetween 2000 and 2500 kcal/day is the resting burn of many average-sized men and larger women.
≥ 2500 kcalHigh BMRAbove 2500 kcal/day reflects a large frame or high lean body mass — common in taller, muscular adults and male athletes.

BMR Formula

BMR=10 × weight + 6.25 × height − 5 × age + sex offset

BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) + sex offset (+5 for men, −161 for women).
