Frequently Asked Questions
What is BMR?
Basal Metabolic Rate is the number of calories your body burns at complete rest just to keep you alive, such as breathing and circulation. It is the starting point for your daily calorie needs.
What is TDEE?
Total Daily Energy Expenditure is your BMR multiplied by an activity factor. It estimates the calories you burn in a typical day including movement and exercise.
Which formula does it use?
It uses the Mifflin-St Jeor equation, which is widely regarded as one of the most accurate everyday formulas for estimating BMR.
How do I use this to lose or gain weight?
Eating around your TDEE keeps your weight steady. Eating below it tends to lose weight, and above it tends to gain. A change of about 500 calories a day is a common starting point.
