Abstract: Recent studies reveal that sleep loss in humans leads to metabolic disorders. A new study reports the development of metabolic syndrome in mice with altered circadian timing brought about by a mutation in a gene that functions in the biological clock. An intriguing and unanswered question is the relation between a healthy biological clock and normal appetite and weight regulation.
