How It Calculates the Results
The calculator uses the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR), which is the number of calories your body needs to maintain basic physiological functions. The BMR is then multiplied by an activity factor to estimate your Total Daily Energy Expenditure (TDEE), which is the total number of calories you need to maintain your current weight based on your activity level. Here’s the equation used:
For Males:
BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5
For Females:
BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161
The activity factors are as follows:
- Sedentary: BMR x 1.2
- Lightly active: BMR x 1.375
- Moderately active: BMR x 1.55
- Active: BMR x 1.725
- Very active: BMR x 1.9
