A few ideas. I would maybe look to finding a schedule that shifted based on it being a work day or day off. This might sacrifice a few hours of fasting when you needed to switch, but would still maintain a reasonable consistency in the long run. So maybe that’s like 16:8, but you shift the hours.
Another approach would be to be less strict on specific fasting hours and focus more on keeping eating to two meals a day with little to no snacking. This would give you a lot of flexibility to place those meals when you needed them.
Finally would be working up to something like OMAD or OMAD+. Trying to get the bulk of your calories in one go, with OMAD+ adding a flexible small meal or snack to play around with the timing of.
