BMR and TDEE explained
What is BMR?
Basal metabolic rate (BMR) is an estimate of the energy your body uses at rest to support essential functions such as breathing and circulation.
What is TDEE?
Total daily energy expenditure (TDEE) estimates the energy used across a full day, including resting needs, digestion and physical activity.
Why activity matters
Calorie calculators commonly estimate BMR and apply an activity factor to approximate TDEE. The factor is a broad estimate; real activity and energy use can differ.
