Frequently Asked Questions
What is BMR?
BMR (Basal Metabolic Rate) is the amount of energy your body uses in 24 hours of complete rest, to maintain vital functions such as breathing, circulation and body temperature.
What's the difference between BMR and TDEE?
BMR represents caloric consumption at absolute rest. TDEE (Total Daily Energy Expenditure) also includes calories burned through daily physical activity. TDEE is calculated by multiplying BMR by an activity factor.
Why is the Mifflin-St Jeor formula used?
The Mifflin-St Jeor formula (1990) is recommended by the American Dietetic Association for its greater accuracy compared to the older Harris-Benedict (1919). It is the most widely used in modern clinical and nutritional practice.
