TDEE calculator
We use the Mifflin-St Jeor equation to estimate basal metabolic rate, then multiply by your activity level to estimate total daily energy expenditure.
How the TDEE calculator works
BMR (basal metabolic rate) is the calories your body burns at rest. We compute it using the Mifflin-St Jeor equation, which is widely cited as the most accurate of the common BMR formulas. Multiplying BMR by an activity factor (1.2 sedentary up to 1.9 extra active) yields total daily energy expenditure (TDEE).
Use TDEE as a starting point, not a prescription — adjust based on real-world results over 2–3 weeks. Set a calorie target next.
