Daily Calorie Needs (TDEE) Calculator

🤰 Pregnancy / Nursing — program principles

General wellness information only — please build any pregnancy or nursing nutrition plan together with your OB/GYN or midwife, not from this tool alone.
Folate, iron, and choline are commonly prioritized in pregnancy — your provider will guide specific targets.
Nursing typically calls for a modest calorie increase — again, best confirmed with your provider.

Your goal below has been preselected to match this program.

How to use this calculator

Enter your sex, age, weight, and height, then pick the activity level that best matches your typical week and your current goal. This uses the Mifflin-St Jeor equation — the formula most commonly used by dietitians because it is more accurate than older formulas (Harris-Benedict) for most adults.

What your result means

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest just to stay alive. TDEE (Total Daily Energy Expenditure) adds your activity level on top — this is your maintenance calorie number. The final target is TDEE adjusted for your goal (roughly -500 kcal/day for a ~0.5 kg/week loss, or +300-500 kcal/day for a lean gain). Once you have this number, the "Generate sample meal plan" button below the result builds a matching multi-day meal plan for you.

"Simple, fast, accurate — matched what my nutritionist calculated almost exactly."
