đŸ”Ĩ Calorie Calculator (TDEE)

Calculate your Total Daily Energy Expenditure (TDEE) and estimate your daily caloric needs. This calculator uses the medically recognized Mifflin-St Jeor equation to estimate your Basal Metabolic Rate (BMR) and adjusts it based on your lifestyle activity level.

Understanding Your Results

Your metabolic target results are derived using two primary metrics:

  • Basal Metabolic Rate (BMR): The number of calories your body needs just to stay alive and function at absolute rest.
  • Total Daily Energy Expenditure (TDEE): Your BMR multiplied by your physical activity factor. This represents the actual number of calories you burn daily.

The Mifflin-St Jeor Equation

Introduced in 1990, the Mifflin-St Jeor equation remains one of the most reliable and clinically trusted formulas globally for calculation of standard energy metrics in healthy adults:
Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
