What Is TDEE?
Total Daily Energy Expenditure (TDEE) represents the total calories your body burns daily, including your basal metabolic rate (BMR), physical activity, and digestion. Understanding TDEE is crucial for achieving your weight goals, whether you aim to lose, gain, or maintain weight.
How to Calculate TDEE
-
Step 1: Calculate BMR
The Mifflin-St Jeor Equation is used:
- Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
- Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
-
Step 2: Multiply by Activity Level
Once you have your BMR, multiply it by an activity multiplier:
Activity Level Multiplier Description Sedentary 1.2 Little to no exercise Lightly active 1.375 Light exercise (1–3 days per week) Moderately active 1.55 Moderate exercise (3–5 days per week) Very active 1.725 Hard exercise (6–7 days per week) Super active 1.9 Very intense exercise or physical job -
Step 3: Adjust for Goals
For weight loss, consume fewer calories than your TDEE. For weight gain, add more calories to your TDEE. For maintenance, match your calorie intake to your TDEE.
Example Calculation
Let's calculate TDEE for a 25-year-old man, 75 kg, 180 cm tall, with a moderate activity level:
- BMR: BMR = (10 × 75) + (6.25 × 180) - (5 × 25) + 5 = 1755 kcal
- TDEE: TDEE = BMR × Activity Multiplier = 1755 × 1.55 = 2720 kcal/day
