I had a completely low carb Xmas last year, and intend to do the same this year. What helped was:
Some seriously nice meat platters I could pick at - I know Serrano etc is processed but I decided I was going for it over the holidays
Ditto cheese, with celery. I possibly relaxed slightly with this as I had the odd slice of Stilton with apricot.
A pre-Xmas visit to hotel chocolat. I used the 90% stuff to make mint chocolate, chilli and sea salt chocolate, a few chocolate Brazils and their ridiculously expensive drinking chocolate which I made with cream and water and a squoosh of unsweetened squirts cream.
Beanies coffees, served with cream.
All the green veg, made in different ways - roasted, chilli-ed, serve with cream and bacon sauces, butter sauces etc
All the piggies in blankets I wanted!
Posh sparkly water, which I dropped a few mint leave and cucumber in.
A firm resolve that Xmas was not about stuffing a box of quality street down my chops, but rather enjoying time with people, and a reminder how liberating it would be not to have yet another moment serable January reflecting on how much I’d eaten. I don’t normally have much cream at all, so that in itself was a treat. I was at that point chasing 11.13, which I made on NYD :)
We did have quality street, mince pies, after eights, Baileys etc in the house for others, but I just didn’t even consider they were for me.
