How it Calculates the Results
The Basal Metabolic Rate (BMR) is calculated based on the Harris-Benedict formula:
- For men: BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) – (5.677 × age in years)
- For women: BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) – (4.330 × age in years)
The Total Daily Energy Expenditure (TDEE) is calculated by multiplying the BMR by an activity factor that corresponds to your typical activity level:
- Sedentary: BMR × 1.2
- Lightly Active: BMR × 1.375
- Moderately Active: BMR × 1.55
- Very Active: BMR × 1.725
- Super Active: BMR × 1.9
