I’ve done this and found the 16/8 to be realistic, especially considering you are sleeping through most of it. I don’t normally like to eat as soon as I get up. Love breakfast food, but I’m not a breakfast first thing in the morning kind of person. My problem is postponing coffee until later in the day. I don’t like taking it black. I like it blonde and sweet. So every so often, I slip up so I can have my coffee a little sooner rather than later.
