Frequently Asked Questions
What is the BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions (like breathing and heart rate) at rest.
How is the activity level used?
We multiply your BMR by an activity factor (TDEE formula) to estimate your total daily energy expenditure based on how much you move.
Is this accurate for athletes?
The Mifflin-St Jeor formula is widely considered accurate for most people, but body fat percentage can affect results. Highly muscular individuals might need more calories than estimated.
