📊 BMR & Activity Breakdown

Parameter Value Unit

How the formula works

BMR (Mifflin-St Jeor) = 10 × Weight + 6.25 × Height − 5 × Age + S  |  S = 5 (Male) or -161 (Female)
  • BMR (Basal Metabolic Rate) = Calories burned at complete rest
  • TDEE (Total Daily Energy Expenditure) = BMR × Activity Factor
  • Activity Factors: Sedentary = 1.2, Light = 1.375, Moderate = 1.55, Active = 1.725, Extra = 1.9
  • BMI (Body Mass Index) = Weight ÷ Height² (kg/m²)
  • BMI Categories: Underweight < 18.5, Normal 18.5-24.9, Overweight 25-29.9, Obese ≥ 30
  • Weight Status = Based on BMI classification
  • Daily Calorie Goal = For weight maintenance (TDEE)
