Is BMR the same as maintenance calories?
No. BMR is resting energy use. Maintenance calories are higher because they include movement, exercise, and the energy cost of daily living.
BMR이란 무엇이고 왜 중요한가요
BMR이 무엇을 뜻하는지, 하루 기준과 어떻게 다른지, 실용적으로 볼 수 있게 정리했습니다.
Short answer
BMR is your basal metabolic rate, or the energy your body needs at rest. It is not your maintenance calories and it is not your fat-loss target. It is the starting layer of the estimate. Activity, body composition, and real-world weight trends still matter after that first number appears.

BMR 읽는 법
BMR은 무엇을 보여주나요?
BMR은 가만히 있을 때 몸이 쓰는 기본 에너지입니다. 하루 총량이 아니라, 먼저 봐야 하는 바닥값에 가깝습니다.
결과는 어떻게 읽나요?
BMR은 혼자 보면 끝나는 숫자가 아닙니다. 활동량, 목표, 체중 변화까지 함께 봐야 훨씬 잘 쓰입니다.
어디서 오해하기 쉬운가요?
BMR을 내 몸에 딱 맞는 완벽한 기준처럼 받아들이는 게 가장 흔한 오해입니다. 출발점으로 보는 편이 맞습니다.
그다음엔 뭘 보나요?
BMR을 본 뒤에는 하루 기준, 식품 데이터, 칼로리 적자 설명으로 이어 가면 흐름이 자연스럽습니다.
BMR FAQ
Which BMR equation is usually used in calculators?
Many calculators use Mifflin-St Jeor because it has been one of the better-performing practical equations in comparative reviews. Some tools also offer lean-mass-based formulas when body-fat data are available.
Why can two people with the same BMR need different calorie intakes?
Because daily expenditure is shaped by movement, work, training, and sometimes body-composition differences that a basic equation cannot fully capture. BMR is only the resting layer.
Should I eat at my BMR to lose weight?
Usually not. For most people that would be more restrictive than necessary because BMR is lower than maintenance. A workable fat-loss target is generally set below maintenance, not at the resting floor.
