Calculate your Basal Metabolic Rate (BMR) — the number of calories your body burns at complete rest. Supports Mifflin-St Jeor, Harris-Benedict, and Katch-McArdle formulas.
BMR is calories burned at complete rest. TDEE multiplies BMR by an activity factor to estimate total daily calorie burn including exercise and movement.
The Mifflin-St Jeor equation is considered the most accurate for most people. Katch-McArdle is more accurate if you know your body fat percentage.
