Your Total Daily Energy Expenditure (TDEE) is the number of calories your body burns each day — the foundation of any weight goal. This calculator uses the Mifflin-St Jeor equation, the formula the Academy of Nutrition and Dietetics considers most accurate for healthy adults, then adjusts for your activity level.
About this tool
Using your numbers: Eat at your TDEE to maintain your current weight. A deficit of roughly 500 calories per day supports gradual weight loss of about 0.5 kg (1 lb) per week; a similar surplus supports steady gain. Avoid dropping below 1,200 calories (women) or 1,500 (men) without medical supervision.
