learn.whatIsHeading
Total daily energy expenditure (TDEE) estimates calories burned daily. Used for weight management and nutritional planning.
נוסחה
TDEE = BMR × Activity factor
- BMR
- BMR value — Variable used in the calculation
מדריך שלב אחר שלב
- 1Calculate BMR/RMR using Harris-Benedict or Mifflin-St Jeor formula
- 2Multiply by activity factor: 1.2 (sedentary) to 1.9 (very active)
- 3TDEE = BMR × Activity factor
Worked Examples
קלט
70 kg, 175 cm, 40 yo male, moderate exercise
תוצאה
BMR ≈ 1700, TDEE ≈ 2550 cal/day
For weight maintenance
Common Mistakes to Avoid
- ✕Over-estimating activity levels
- ✕Assuming TDEE is constant (it adapts to diet)
Frequently Asked Questions
Which formula is most accurate?
Mifflin-St Jeor is more accurate than Harris-Benedict for modern populations.
How does TDEE change with diet/exercise?
Severe caloric restriction reduces TDEE (adaptive thermogenesis). Exercise increases it.
