Are chronic sleep deprivation and call nights making you fat?

A new study out in the journal Science Translational Medicine makes a direct link between disregulated sleep and metabolic derrangements that lead to poor health and weight gain. While there have been several epidemiological studies drawing correlation between sleep deprivation and hyperglycemia, impaired glucose tolerance, and decreased immune function, the difference with this new prospective cohort study is that the researchers controlled participants' sleep cycles over a relatively long period of time (just over a month) while directly measuring their metabolic markers. When they were forced to sleep 5.6 hours/night, the subjects exhibited slower metabolic rates and higher levels of postprandial glucose... bad news for those of us who are forced to sleep even less than 5.6 hours on certain heinous call nights!
