if you are very strict or semi strict about your eight hour feeding window, but on the weekends that eight hour feeding window is falling later than it normally would during the middle of the week. It is as if you are going to bed later, even if you're going to bed at the same time, at least from the perspective of metabolic health, because of the way that eating impacts these clock genes and impacts, or I should say subtracts, the sleep-related fasting that you would normally experience if you were to finish eating that a couple hours before bedtime.
