Breastfeeding Calorie Needs Calculator
Producing breast milk requires a significant amount of energy from your body—often more than you might expect! Depending on how frequently your baby feeds, you may need an additional 300 to 600 calories per day on top of your baseline needs.
This calculator uses the widely-trusted Mifflin-St Jeor formula to determine your baseline metabolic rate, then applies a daily activity multiplier, and finally adds the energy required for lactation based on your baby's feeding frequency. Use this to ensure you're providing your body with the fuel it needs.
