'Night eating syndrome' may be related to the performance of the body -- not the mind
...sed CRH stimulation may involve alterations in the neurotransmitter systems, causing increased nocturnal appetite and disruption in the sleep pattern. This may, to some extent, explain the disturbances in the circadian secretions of melatonin and leptin and the behavioral characteristics of the night eating syndrome....Hypoglycemia may affect newborn's brain cell function, says Hopkins researcher
