Tag: Calories per kg

According to the National Institutes of Health, a healthy newborn requires roughly 100-120 kcal per kilogram of body weight daily, a figure that is significantly higher per kilogram than an adult's requirement. This elevated demand for energy is driven by the extraordinary physical growth and developmental processes that occur during infancy.

Infants require an average of 100 to 120 kilocalories per kilogram of body weight daily, a rate significantly higher than at any other point in life. This means that infancy is the stage of development that requires the greatest number of calories per kilogram of body weight. The reason lies in the immense energy expenditure necessary to fuel rapid growth, sustain a high metabolic rate, and support continuous brain and organ development.

Research shows an infant's resting energy expenditure can be two to three times that of an adult when standardized for body weight. This remarkable metabolic rate underscores the fact that infancy is the stage of development during which energy needs relative to body weight are the highest, driven by the phenomenal pace of growth and physiological maturation.

A newborn requires approximately 100-120 kcal/kg/day, a significantly higher energy intake per unit of body weight than at any other point in the human life cycle. This intense demand confirms that infancy is the life stage where energy requirements per pound of body weight are the highest, a fact driven by explosive growth and rapid development.
