How many additional calories does a breastfeeding woman require per day compared to a non-breastfeeding woman?

A breastfeeding woman requires approximately 330 additional calories per day compared to a non-breastfeeding woman. This increased caloric need is essential to support the production of breast milk, which is a nutrient-dense substance necessary for the growth and development of the infant.

During lactation, a woman’s body undergoes significant physiological changes that require increased energy intake. The calories are utilized not just for milk production but also for the woman's overall energy needs as she is nurturing and caring for her newborn. Research has shown that an increase of around 330 calories daily is optimal to meet these demands and ensure both maternal health and adequate milk supply.

The additional calorie requirement is also important to help maintain the mother’s energy levels, which may be otherwise impacted by the physical demands of breastfeeding and caring for an infant. Proper nutrition and adequate calorie intake are crucial for a breastfeeding woman to support her own health as well as her baby's nutritional needs.
