Our breastfeeding calorie calculator uses the Mifflin-St Jeor equation to calculate your Base Metabolic Rate (BMR), then applies activity multipliers and adds breastfeeding calories based on nursing type and baby's age. The calculator provides personalized nutrition recommendations to support healthy milk production while meeting your postpartum health goals.

Breastfeeding Nutrition Principles

Breastfeeding mothers need additional calories, increased hydration, and specific nutrients to support milk production and maintain their own health. The key is consuming nutrient-dense foods rather than empty calories, staying well-hydrated, and ensuring adequate protein intake for tissue repair and milk production.

• Exclusive breastfeeding burns approximately 500 calories per day
• Protein needs increase to 1.5-1.8g per kg body weight
• Hydration requirements increase by 1 liter (33 oz) per day
• Minimum 1800 calories daily to maintain healthy milk supply
• Safe postpartum weight loss: 0.5-0.7kg (1-1.5 lbs) per week maximum
• Key nutrients: calcium, iron, vitamin D, DHA/omega-3, vitamin A
