Break up dinner and dessert with a walk outside or some sort of family activity. I know a few people who will be Wii bowling with their kids during the day. If you prepare ahead by making any dishes that can be fully or partially prepared the day or so before, you'll have more free time on Thanksgiving morning.
Make sure to eat breakfast and don't graze while cooking. Try to stick to eating lighter every few hours. Remember, it's not a rule that YOU have to get completely stuffed.
Limit calorie-laden beverages. Drink water throughout the day, and sip on peppermint tea after meals to aid digestion. Limit juices, punches, cider and eggnog.
During the meal, eat slowly -- you'll register feeling full more quickly. Put your fork down between bites, eat the turkey and veggies first,then the stuffings and casseroles, if you must.
Offer to help with the clean-up and dishes -- the host will love you and you'll get to move around. Plus, it's harder to keep reaching for pie with dirty, soapy hands.
