"Ketone bodies are a major fuel for the brain during the suckling period and hence the stimulation of ketogenesis at birth is an important metabolic event in adaptation of the newborn to extrauterine life. Ketogenesis is active during late gestation in human fetal liver and the activity of ketogenic enzymes sharply increases immediately after birth in the rat (Hahn and Novak, 1985; Bougneres et al., 1986).

"During the first 8 h after birth, newborn infants have been shown to have rather low plasma ketone body concentrations despite adequate levels of precursor free fatty acids (FFAs), reflecting limited capacity for hepatic ketogenesis.30 Thereafter, from 12 h of age, healthy term infants show high ketone body turnover rates (12e 22 mmol kg/min) approaching those found in adults after several days of fasting,14 and during days 2 and 3 after birth they exhibit high ketone body concentrations quantitatively similar to those observed after an overnight fast in older children (Fig. 2).15 Such ketone body concentrations may account for as much as 25% of the neonate?s basal energy requirements during this time. Thus vigorous ketogenesis appears to be an integral part of extrauterine metabolic adaptation in the term human neonate."
