Total Daily Energy Expenditure Calculator
Calculate your exact Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) using the peer-reviewed Mifflin-St Jeor equation to pinpoint your ideal fat-loss calorie deficit.
Why Precise Calorie Deficit Targets Matter
Your Total Daily Energy Expenditure represents the exact number of calories your body burns every 24 hours through metabolic function, movement, digestion, and exercise. A sustainable 20% deficit preserves lean muscle mass while maximizing fat oxidation.
