How This Breastfeeding Works

The calculator uses the Mifflin-St Jeor equation to find your base metabolic rate, then multiplies by activity level. For breastfeeding, it adds approximately 500 calories for exclusive nursing or 250 for partial nursing, based on clinical guidelines for lactation energy demands.

When Should You Use This Tool

Use this calculator during the postpartum period while breastfeeding to ensure adequate nutrition. Recalculate as your baby grows, as calorie needs may shift when introducing solid foods or reducing feeding frequency.

Is This Tool Accurate and Safe

Calorie needs vary based on individual metabolism, baby's feeding patterns, and recovery status. This provides general guidance based on established nutritional science. Consult your healthcare provider for personalized postpartum nutrition advice. All data stays in your browser.

Frequently Asked Questions

How many extra calories do breastfeeding mothers need?

Exclusively breastfeeding mothers typically need 450-500 extra calories daily. Partial nursing requires approximately 250 extra calories. These numbers decrease as solid foods are introduced to baby.

Can I diet while breastfeeding?

Rapid weight loss can affect milk supply. Most experts recommend no more than 1-2 pounds of weight loss per week during breastfeeding. Focus on nutrient-dense foods rather than calorie restriction.

What foods support breast milk production?

Oats, salmon, eggs, leafy greens, and legumes are commonly recommended. Staying well-hydrated is essential. No specific food is proven to dramatically increase supply, but overall nutrition matters.

Will eating less reduce my milk supply?

Severe calorie restriction can reduce milk supply and affect milk quality. Your body prioritizes milk production, but chronically low intake may impact both your energy and your baby's nutrition.
