A pretty good rundown of research until they get to the conclusion-
“Ongoing and future studies will show whether interventions to improve sleep duration and quality can prevent or even reverse metabolic traits,” the review authors wrote. “Meanwhile … health care professionals can be safely recommended to motivate their patients to enjoy sufficient sleep at the right time of day.”
They flat-out state the studies haven't been done, but they recommend it anyway...
And for the record, it works the other way- better metabolic control improves sleep.
