Your BMR is about 1,649 kcal/day (6,898 kJ).

  • This is the energy your body uses at complete rest, computed with the Mifflin-St Jeor formula, for breathing, circulation and keeping warm.
  • Your real daily need is higher: a sedentary day is about 1,979 kcal, and a very active day about 2,844 kcal.
  • BMR falls gradually with age and rises with lean muscle mass, so resistance training can lift it over time.

Next stepUse the Calorie (TDEE) calculator to set a precise maintenance, weight-loss or weight-gain target for your activity level.
