The Calorie Calculator uses three main equations for estimating daily calorie needs: the Harris-Benedict Equation (revised in 1984), the Mifflin-St Jeor Equation (introduced in 1990, known for its accuracy), and the Katch-McArdle Formula (which considers lean body mass for more precise estimation, particularly useful for lean individuals).

  • Mifflin-St Jeor Equation:
    • For men: BMR = 10W + 6.25H – 5A + 5
    • For women: BMR = 10W + 6.25H – 5A – 161
  • Revised Harris-Benedict Equation:
    • For men: BMR = 13.397W + 4.799H – 5.677A + 88.362
    • For women: BMR = 9.247W + 3.098H – 4.330A + 447.593
  • Katch-McArdle Formula:
    • BMR = 370 + 21.6(1 – F)W
  • W is body weight in kilograms (kg)
  • H is body height in centimetres (cm)
  • A is age in years
  • F is the body fat percentage
