Hi @SarahW and welcome!
Good to hear that fasting is starting well for you.
Just to clarify the different approach to fasting of 5:2 and 16:8 (and apologies if you are already very clear on these)...
With 5:2, you have 2 days a week where you eat very little (about 500 cal), and the other 5 days where you eat "normally". For someone who isn't a shift worker, on the day before a fast day, you stop eating after dinner; on the fast day you only consume a small amount of cals - most people reserve this for the dinner time meal, but some split it across the day; and then don't eat again until your first meal the day after. So there should be about a 36 hour period during which you only eat about 500 cals.
When you are a shift worker, obviously you have to change the times, but the aim would be to still have a 36 or so hour period with max 500 cals consumed, twice a week.
16:8 is windows eating, where every 24 hours you only eat in an 8 hour window. Many people aim to narrow that window further, eg only eat in a 5 hour window. Some go so far as to only have one meal a day. And you eat within the window every day (you can shift the start times for the window of course).
Different styles of fasting appeal to different types of people. Sometimes you know what will work for you (5:2 worked for me, whereas restricting my eating to only a few hours a day every day never would!), other times you need to try one style for a while - give it at least a few weeks - before trying something else.
Best wishes for whatever method you choose. Good luck!
