Daily Calorie Needs (TDEE) Calculator

🌗 After 50 — program principles

  • Calcium + vitamin D rich foods (dairy, leafy greens, fatty fish) for bone density.
  • Lean protein and healthy fats over saturated fat for cardiovascular health.
  • Keep resistance-friendly protein intake up — this pairs with strength training, not diet alone.

Your goal below has been preselected to match this program.

How to use this calculator

Enter your sex, age, weight, and height, then pick the activity level that best matches your typical week and your current goal. This uses the Mifflin-St Jeor equation — the formula most commonly used by dietitians because it is more accurate than older formulas (Harris-Benedict) for most adults.

What your result means

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest just to stay alive. TDEE (Total Daily Energy Expenditure) adds your activity level on top — this is your maintenance calorie number. The final target is TDEE adjusted for your goal (roughly -500 kcal/day for a ~0.5 kg/week loss, or +300-500 kcal/day for a lean gain). Once you have this number, the "Generate sample meal plan" button below the result builds a matching multi-day meal plan for you.

"Finally a TDEE calculator that explains BMR vs TDEE instead of just spitting out a number. Used it to plan my whole week."

"Simple, fast, accurate — matched what my nutritionist calculated almost exactly."
