"Eating your last meal of the day well before bed has become standard advice among many nutrition experts.
It’s often been attributed to giving the body time to rest and digest and to a better alignment with the body’s circadian rhythms that dictate metabolic power.
This study looks at one mechanism behind why we notice benefits from eating an early dinner: Eating late is associated with impaired glucose tolerance from decreased insulin production, which increases the risk of type 2 diabetes.
Researchers found that certain genetic markers related to melatonin receptors also play a role in the possible risks of late eating." (Dr. M. Hyman)
