Understanding Your Result
The calculation generated by this tool provides an evidence-based assessment derived from established physiological and clinical equations. Use this measurement as an educational indicator alongside broader lifestyle variables, including overall dietary quality, resistance training, cardiovascular endurance, and routine medical checkups.
Mathematical Formula & Scientific Methodology
TDEE represents the total calories burned in a 24-hour period, comprising BMR (60-70%), NEAT (15%), TEF (10%), and EAT (5-10%). TDEE = BMR × Activity Multiplier.
Step-by-Step Example Calculation
Clinical Limitations & Nuances
People frequently overestimate their workout intensity and underestimate sedentary desk hours. Start with a conservative activity multiplier.
Frequently Asked Questions
What are the 6 activity multipliers used in TDEE?
Sedentary (1.2), Lightly Active (1.375), Moderately Active (1.55), Very Active (1.725), Extremely Active (1.9).
How does NEAT affect my TDEE?
Non-Exercise Activity Thermogenesis (NEAT)—such as walking, standing, and moving throughout the day—can vary TDEE by up to 800 kcal between individuals with similar workouts.
