Formula and Logic

This tool uses the Mifflin-St Jeor Equation to estimate Basal Metabolic Rate (BMR), which is the calories your body needs at rest. Total Daily Energy Expenditure (TDEE) is calculated by multiplying BMR by an activity factor. Target calories are adjusted by ±500 kcal for weight loss or gain goals, aligning with common dietary guidelines.

Practical Notes

  • Individual metabolism varies; use these estimates as a starting point and adjust based on progress.
  • Consult a healthcare provider or dietitian before making significant dietary changes, especially if you have medical conditions.
  • For athletes, consider periodizing nutrition—adjust calories during training vs. competition phases.
  • Protein intake recommendations support muscle recovery; combine with balanced carbs and fats.
