Total Daily Energy Expenditure (TDEE) represents the total calories your body uses over a 24-hour period. It is the sum of three components: your Basal Metabolic Rate (BMR), which accounts for the energy needed to sustain basic life functions at rest; the thermic effect of food (TEF), which is the energy used to digest and absorb nutrients; and your physical activity level, including both structured exercise and non-exercise activity thermogenesis (NEAT) like walking and fidgeting.
Understanding your TDEE is essential for managing body weight. To lose fat, you need to consume fewer calories than your TDEE (a calorie deficit). To gain weight or build muscle, you need a calorie surplus above your TDEE. Maintaining weight means eating roughly at your TDEE level. Without knowing this number, nutrition plans are essentially guesswork.
TDEE varies significantly from person to person based on age, sex, body composition, activity level, and metabolic health. Someone who exercises intensely every day may have a TDEE double that of a sedentary person of the same size. Hormonal factors, sleep quality, and stress also influence daily energy expenditure in ways that static formulas cannot fully capture.
Vora calculates an estimated TDEE by combining your profile data with real-time activity tracking from wearables. This dynamic approach gives a more accurate picture than static online calculators, adjusting for daily variations in exercise, step count, and recovery status so you can dial in your nutrition with confidence.
