How many kilocalories per day does a healthy term newborn typically require?

A healthy term newborn typically requires about 100 to 120 kilocalories (kcal) per kilogram of body weight per day. Given that the average weight of a term newborn is around 3 to 4 kilograms, this translates to a daily caloric requirement of approximately 300 to 480 kcal, with most estimates placing the average need at around 330 kcal per day. This intake is essential for proper growth and development during the neonatal period, as it supports metabolic processes, energy needs, and overall physiological functioning.

The value of 330 kcal/day aligns well with clinical guidelines and nutritional recommendations for this age group, reflecting the adequacy needed to support a healthy newborn’s growth during their early life stages. Understanding these requirements is crucial for providing appropriate nutritional care and ensuring the well-being of newborns in a clinical setting.
