Hello, Lynne (SACTLynne) – I hope all goes well on your first two fasts. Spread your fast day meals (and your weekly schedule) in whichever way best suits your situation and inclination – either of the possibilities you quote will give the same health and weight-loss results. It can take quite a while to discover the timetable you most prefer, so experiment if necessary – the 5:2 system is very flexible. Perhaps take a look at the faq link – frequently asked questions – at the top-right of the page, under the heading ‘Welcome to 5:2 Intermittent Fasting’. There’s a lot of good, basic information up there. I wish you much delight and success in using this new approach.
