The new research linking blood sugar and the internal clock may help develop and improve strategies for controlling glucose levels in day-active people and night workers, reports Harvard Gazette.

“Our study underscores that it’s not just what you eat, but also when you eat that greatly influences blood-sugar regulation, and that has important health consequences,” said co-corresponding author Frank Scheer, Harvard Medical School (HMS) associate neuroscientist and assistant professor of medicine in the Division of Sleep and Circadian Disorders and Departments of Medicine and Neurology at BWH. “Our findings suggest that the circadian system strongly affects glucose tolerance, independent from the feeding/fasting and sleep/wake cycles.”
