How this calorie calculator works

  • We compute your Basal Metabolic Rate (BMR) using the formula you selected.
  • BMR is multiplied by your chosen activity factor to estimate Total Daily Energy Expenditure (TDEE).
  • Finally, we adjust calories based on your goal intensity and convert that target into macros and per-meal guidance.

How to use your calorie results safely

  • Treat this calculator as a planning guide, not a medical prescription.
  • Stay within safe deficit/surplus ranges (5–20%) unless your healthcare provider advises otherwise.
  • Recalculate as your weight, training, or lifestyle changes so TDEE stays accurate.
  • Combine calorie tracking with sleep, stress management, and resistance training for best results.
