In-Depth Guide & Mathematical Methodology
⚡ Components of Total Daily Energy Expenditure
Basal Metabolic Rate (BMR ~60-70%): Calories burned at complete rest to keep organs functioning.
NEAT (~15%): Non-Exercise Activity Thermogenesis (walking, fidgeting, posture).
EAT (~10-15%): Exercise Activity Thermogenesis (planned workouts).
TEF (~10%): Thermic Effect of Food (energy required to digest protein, carbs, fats).
Frequently Asked Questions (FAQ)
What is the TDEE Calculator (Total Daily Energy Expenditure) and how does it work?
Total metabolic expenditure audit. Multiplies Basal Metabolic Rate (BMR via Mifflin-St Jeor or Katch-McArdle) by Physical Activity Level (PAL) to establish precise calorie deficit or surplus targets.
How do I use this TDEE Calculator (Total Daily Energy Expenditure)?
Select biological sex, age, height, and body weight. Select physical activity level (PAL multiplier). If body fat % is known, choose Katch-McArdle formula. View maintenance TDEE and target calories for fat loss or muscle gain.
What mathematical formula is used in this calculation?
TDEE Equation = BMR × PAL. BMR via Mifflin-St Jeor (1990) or Katch-McArdle (1996). PAL Multiplier: Sedentary (1.2), Light (1.375), Moderate (1.55), Heavy (1.725), Extreme (1.9).
