About these numbers
BMR is the energy your body uses at complete rest; multiplying it by an activity factor gives an estimate of daily maintenance calories. A deficit of roughly 500 kcal/day corresponds to losing about one pound per week. These are population estimates — individual needs vary, so treat them as a starting point, not a prescription.
