Work out daily calories while breastfeeding, by feeding stage and activity level.
Breastfeeding calorie needs are calculated by adding 400-500 additional calories to a mother's TDEE to account for the energy cost of milk production, which produces approximately 750 mL of breast milk per day.
Formula
Total Calories = TDEE + Breastfeeding Bonus (300 to 500 cal) | TDEE = BMR × Activity FactorBMR = Basal Metabolic Rate calculated using Mifflin-St Jeor equation
Activity Factor = Multiplier based on daily activity level (1.2 to 1.725)
Breastfeeding Bonus = +500 cal for exclusive breastfeeding, +300 for partial
Worked Example
65 kg, 165 cm, 30 years, light activity, exclusive breastfeeding
Did you know? Producing 1 liter of breast milk requires approximately 670 calories. The body draws about 170 of these from fat stores, which is why exclusive breastfeeding can aid postpartum weight loss (source: CDC).
