As you take your last bite or your last sip of calories  Truuburn Keto Max

 there's this time or taper before, which you are actually in a fasted state. And because you're eating different things on different days, presumably some foods leave your gut more quickly. Some things spike your insulin and your glucose more than others. Sometimes you eat more fat, sometimes less fat. This allows you to fall well within the margins of the benefits of time-restricted feeding that had been demonstrated in humans, which generally involve an eight hour window or so. So I think this eight hour window or six hour window.
