Hi
@Georgiesgirl, it will be the same for me. Christmas dins is ok as I'll just have everything bar the stuffing and the taters, but Christmas Eve (when we go to my dad's) will be a massive problem as it's all buffet food: butties, pizza, sausage rolls, pork pie, crisps etc. My sister will get me some nice cheeses, low carb crackers and celery sticks to nosh on, but it will be hard resisting the other stuff which I've avoided since April.
You'll need to check the carb content of anything you order. I imagine christmas pud is out of bounds, so maybe you could have something like berries and double cream (zero carbs for the cream) as your dessert. You can google the carb content of everything you fancy ordering...you may be surprised at how much you can get away with.
My biggest disappointment will be on Boxing Day. No bubble & squeak for me this year though I may try doing a non potato version with the left-over veg. Also, it's the only day of the year I normally eat sweet things. Lying on the sofa in front of a roaring fire drinking coffee and stuffing quality street down my throat. Sigh, happy days.
Will you be cooking for non-diabetics as well? I think that's probably the hardest bit, which is where Mr Google comes in so handy for what you can share with the non-diabetics and what you have to forego.
