This year, I'm thankful for the fact that I wasn't born into a "Turkey Trot" family. I admire those families, but heck if there isn't anything I'd like to do less than run a 5k on a day when I'm supposed to just be eating a ton of mac and cheese. I was, however, born into a family that does Thanksgiving at dinner time (around 7 or even 8 PM). When I found out that most families get to their turkeys in the early afternoon, I was puzzled. But that does solve the problem of what you eat during the rest of the day so you don't get too full-- you just eat one giant meal at 2 PM and then fall asleep after the dishes are done.
But however you celebrate, all that matters is that you eat something delicious and take a moment to remember what you're grateful for. And then you can gather the family around this meme list, like a hearth.
