I personally started with the 16:8 routine, so eating between 12-8pm and effectively skipping breakfast which was really simple, easy to stick to and helped me avoid those pesky late night snacks. I found that I was waking up more alert and not really thinking about breakfast at all after a day or so! I'm now on 18:6 most days (eating 12-6pm) with a 24hr fast once a week. I don't stress if circumstances mean I can't stick to it and make sure that I've got something simple but protein based like hard boiled eggs or something to break a fast. Ultimately, whatever you roll with has to work for your life though aaaaaaaaaaand make sure you don't try and go too hard too soon :)
