Study Examines How Circadian System, Behavioral Cycles May Affect Glucose Tolerance, Pancreatic Beta-Cell Function.

a study published this week in the Proceedings of the National Academy of Sciences reveals that “glucose tolerance is lower in the evening than in the morning – and the body’s internal clock and misalignment of that clock with behavior can affect the level of tolerance.” The 14-participant study examined “how the circadian system and behavioral cycles like meal and sleep time – as well as the misalignment of those two factors – affected glucose tolerance and pancreatic beta-cell function.” Researchers “found that postprandial glucose was 17% higher in the evening independent of any behavioral cycles.” http://www.medpagetoday.com/Endocrinology/MetabolicSyndrome/51026
