📊 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)
