If you have ever tried to lose weight, build muscle, or maintain your physique, you have likely encountered the term TDEE: Total Daily Energy Expenditure. TDEE represents the exact number of calories your body burns in a 24-hour cycle across all physiological functions and movements.
Your daily caloric burn is not just about time spent in the gym. It consists of four distinct metabolic compartments:
To calculate TDEE, we first compute BMR using the clinically validated Mifflin-St Jeor equation:
For Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
For Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
Next, multiply BMR by an activity factor:

BMR is the base calories burned just staying alive at complete rest, while TDEE accounts for all physical activity, digestion, and daily movement.
Non-Exercise Activity Thermogenesis (NEAT) includes all non-structured movement throughout the day, such as walking, typing, fidgeting, and household chores.
