Frequently Asked Questions
What is BMR?
Basal Metabolic Rate is the number of calories your body burns at complete rest just to maintain basic functions (breathing, circulation, cell production). It does not include any activity.
What is TDEE?
Total Daily Energy Expenditure is BMR multiplied by an activity factor. It estimates how many calories you burn per day including activity. This is your maintenance level.
Which formula does this use?
Mifflin-St Jeor (1990), considered the most accurate for most people. It uses weight, height, age, and gender.
How accurate is this?
It's an estimate. Individual variation is ±10%. Use it as a starting point and adjust based on actual results over 2-3 weeks.
