So if you are like most people and you sleep at night, you're waking up somewhere around 6:30, 7:00 AM, or maybe even 8:00 AM. Let's say you were to push your fasting window out, such that you started eating at noon, and then you stopped eating at 6:00 PM. Well, then you're not eating from 6:00 PM until let's say your bedtime is 10:00 PM, but from 6:00 PM to 10:00 PM, your body is not yet in a fasted state because you just ate. However, you're starting to taper into a fastest state before sleep and then all through sleep. And until the next morning and late morning, you are actually in a fasted state, now, most people find it very hard to only eat in the middle of the day, so while that's best, it's ideal for sake of the fasting related improvements in health, it is not ideal. And it's not very applicable to most work and family and social situations.
