Do you end up eating too much at Christmas?

Naturally. Tis the season after all.

Had to mention the cricket didn't you.

I think I eat a bit too much most of the year (although nowhere near as much as some people)

At Christmas I often eat less as I tend to spend it with relatives who are eating Christmassy food and I've never liked turkey, brussel sprouts, mince pies, Christmas cakes, Christmas pudding, etc
(though I do like chocolate logs and Tunis cakes)

last year covid lockdown meant I spent Christmas by myself so had cod with sweet potato chips as my Christmas meal

I've got a bunch of health problems, so when I am physically capable of eating, I do tend to eat a bit too much. Yesterday I managed two meals--breakfast and dinner, which is unusual for me.

So for dinner I got to eat some very nice marinated steak and roasted carrots, while for breakfast I made a sausage quiche for everyone -- with lots of green bell pepper! I tend not to like sausage quiches so much (sausage is overpowering; asparagus quiche is better) but let's just say... folks in my family tend to like meat.

I also spent most of Xmas Eve's night working on a vanilla cheesecake... found a simple recipe I thought's be easier, but what made it simple was baking at a succession of low temperatures for a very long time... finishing at around 3AM as I recall. So two meals plus a sliver of cheesecake. I think it turned out well! More dense than I'd've preferred, but tasty.

Which, by my standards, is like 2-3 times what I normally eat in a today.

Meanwhile, the only thing on the menu today is water.
