Studies of the diets of sleep-deprived people reveal that they tend to favour foods high in fat over those high in protein [6]. This is not surprising when we consider that eating stimulates the secretion of orexin, the hormone that reduces fatigue. Orexin is associated with reward-driven eating behaviour in which food is not eaten to satisfy hunger but to satisfy an emotional or psychological need. This is believed to result in poor impulse control, which increases the tendency to consume more calories than necessary [8]. In children, sleep deprivation is associated with the increased consumption of unhealthy foods and soft drinks at the expense of fruits and vegetables [11].
