Sleep link to calories: a new study Oct 25th 2012, 11:09 A new study shows that both length of time and percentage of overall sleep spent in different sleep stages are associated with decreased metabolic rate, increased hunger, and increased intake of calories (specifically from fat and carbohydrates). The findings suggest an explanation for the association between sleep problems and obesity. Researchers from St. Luke's-Roosevelt Hospital and Columbia University investigated the effects of sleep architecture on hunger to determine whether specific stages of sleep, rather than simple duration, would affect changes in appetite and food desires in healthy adults. The article is entitled "Alterations in sleep architecture in response to experimental sleep curtailment are associated with signs of positive energy balance" (http://bit.ly/S69LsW). It appears in the online edition of the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology published by the American Physiological Society.
