What BMR means
BMR is the energy your body uses at rest to keep you alive — breathing, circulation, and basic cell work. Daily needs are higher, because you move, digest food, and do everything else on top of rest. The TDEE calculator adds activity to this number.
Frequently asked questions
Should I eat only my BMR?
No. BMR is the floor before activity, not a daily eating target. See a professional before changing your diet.
