Losing a Parent and Obesity

An intriguing new study just published in the International Journal of Psychiatry in Medicine suggests a link between the death of a parent in childhood (or prolonged separation) and obesity as an adult. Researchers in Italy interviewed 120 patients who were undergoing pre-surgical psychiatric consultation for bariatric surgery.

A fascinating article in Scientific American looks at the biochemical, genetic and behavioral foundations of emotional strength, and how that information may help us when our healing processes fail.
