Not sure if this will help, but here are a few suggestions: Start your morning off w/ a great breakfast at home. Make sure you have lots of protein & healthy fats...as they will stay w/you longer. Then before you leave (or before your guests arrive) have some higher protein appetizers. Scallops wrapped in Bacon, Deviled Eggs, Celery w/ Cream Cheese...and make sure you are keeping up w/ your water.
So many of the traditional foods can be tweaked to lower the overall carb counts (or make something similiar but w/ a lower carb food), but I do get that not everyone will want to do this...especially if they are eating with, or feeding a crowd that is NOT on this WOE. However, YOU ARE! You chose this path to better health for yourself! And you owe it to yourself not to create and trigger cravings that could unravel the work you've done this far...so be careful.
Turkey - is fine. A great salad also fine. But take one good look at those marshmellows and realize they could be the culprit to you losing control. When you feel 'tempted' - have a small glass of water, and another protein appetizer...and wait it out...the temptation will pass...and you'll go back to enjoying the lower carb foods that will be available. Have another serving of Turkey...but skip the 'traditional stuff' - and by all means, bring a low carb dessert if you are a dessert eater! Regardless of what the hostess says. Just make light of it...tell them it's a brand new recipe that looked so good to you that you just couldn't resist!
Plan ahead...it will help you the most in making this day about being Thankful, instead of about food!
Live, Love, Laugh ...make each day memorable and enjoy the journey.
