I would probably on Friday eat breakfast and this meal only.
I would probably also skip breakfast on Saturday.
I am sure you will find a good way to incorporate this meal in your system. Flexibility is one of the nice things about IF.
That sounds like a really nice tradition with your family :) if you’re comfortable with doing so, can you share that your trying to make adjustments for a healthier lifestyle to have their support?
You could try adjusting your feeding window or doing a longer fast the following day (18:6 or 20:4)
Fasting can be so flexible. I try to remember that one “bad” meal doesn’t cancel out all of the work you put in before.
Maybe skip the cake and/or pie some weeks - or just have a smaller portion of one. For me, i find if i swear off chocolate/baked goods/carbs I’m miserable and wind up bingeing on something horrible. If i keep those things in moderation - something for a special occasion then it’s a nice thing to look forward to every once in a while and it no longer feels “forbidden”
I hope some of that is helpful! :) you got this!
Politely excuse yourself from the cake at the end. Your stomach has likely shrunk from IF and a sugar bomb is nobody’s friend. Either tell them at beginning you won’t be having cake or claim to be incapable of eating another bite.
