Hi Su, there is no answer to that IMHO. It is highly individual - N=1 - and depends on how important people feel it is to keep control at all times. I don't really like cake but for birthday we have used a keto cake in the past, not this year. Christmas cake or pudding are no loss as I never ate them, mince pies the same. Personally, I do test and analyse my intake but my birthday is in June and I enjoy salad so largely fine. I will have a few cherries and some strawberries then but not on the same day. For Christmas I will have a slice of pannetone well before the day but chose the lowest carb one I can find, test pre and post and adjust other food that day. The bigger issue for me are port, madeira and PX sherry. No idea if any of that helps. I am an outlier on here on many things. I have been non D for 6+ years but am by no means a good example. Just trying to be friendly - don't take my word on anything. I am certain this WOE has to be something you can stick with for life so judicious, well thought out compromises suit many.
