How TDEE Calculator Works & Scientific Formula

Our online TDEE Calculator uses clinically validated physiological formulas for high accuracy. Formula: BMR (Mifflin-St Jeor) × Activity Multiplier (1.2 to 1.9). Calorie Deficit = TDEE - 500 kcal/day (approx. 0.5 kg fat loss/week).

Scientific Formula & Calculation Logic

This calculator executes clinical formulas recognized in medical and physiological literature:

BMR (Mifflin-St Jeor) × Activity Multiplier (1.2 to 1.9). Calorie Deficit = TDEE - 500 kcal/day (approx. 0.5 kg fat loss/week).

Reference Ranges & Health Categories

Category / Classification Reference Value / Range Health Interpretation
• Mild Deficit (Slow & Steady) TDEE - 250 kcal ~0.25 kg loss/week
• Moderate Deficit (Recommended) TDEE - 500 kcal ~0.5 kg loss/week
• Maintenance Exact TDEE Weight stays stable
• Lean Bulking TDEE + 300 kcal Lean muscle gain

Frequently Asked Questions (FAQs)

BMR is the calories your body burns at total rest just to stay alive. TDEE accounts for all your daily physical activities, exercise, and thermic effect of food.
