About Breastfeeding Nutrition
Why Calorie Tracking Matters
Breastfeeding requires additional calories to support milk production and postpartum recovery. The average breastfeeding mother needs about 450-500 extra calories per day when exclusively breastfeeding. This calculator uses the Mifflin-St Jeor equation and adjusts for activity level, breastfeeding frequency, and your weight goal to provide a safe, personalized daily calorie target.
