Stop it. Stop it right now. Don't deprive yourself on turkey day. Eat like you used to with no shame or guilt. If I can do anything beyond lay on a couch and watch football after the meal, I will consider it a failure. You like eating 3 helpings of mashed potatoes covered in gravy? Have them. Can't decide between your mom's pecan pie, and your aunt's pumpkin cookies? Don't, then go ahead and return to the egg nog bowl multiple times. Let yourself have that Thursday to just relax and let all the stress go.
I have to weigh in as a featherweight the next weekend for a competition, and I still plan on eating whatever catches my eye on Thursday. The trick is keeping it a holiDAY, not a holiMONTH. I don't have to be the one to demolish the leftovers over the weekend. And I need to not graze on the cookies that will be left out afterword. Those are the healthy lifestyle changes this site has the right idea about. A healthy lifestyle also includes bingeing on a special meal if that's what you want to do, and enjoy doing in the company of friends and family.
