So in the context of intermittent fasting, it's really not an issue of whether or not your feeding window is 8 hours or 12 hours. It's really an issue of whether or not you're getting enough calories to offset the physical demands and activities of your life, whether or not you're on a maintenance diet to maintain your weight. And of course, you have to put all that in the context of whether or not you're overweight or lean to begin with.
