I have no idea what's going to happen. I think it is easier to stay on plan for thanksgiving than for christmas. The emphasis is on dessert more for christmas.
For thanksgiving, we always have turkey, escarole soup, a green veggie or two, squash, etc. It is mostly on plan, besides stuffing and potatoes, and dessert if a guest brings some.
I may have some stuffing. Mashed potatoes are my favorite food, but I wouldnt eat those. They are just potatoes. My dad only makes stuffing once a year, and it aint stovetop, so that may be something I will have.
I wouldnt really eat off plan desserts, not when I can make my own lc cheesecake. So I'm guessing I may have a portion controlled bit of stuffing, but otherwise, I'll be on plan. No need to go off when there are acceptable subsitutions I can make.
But I think if one wants to go off, for their own reasons, its ok. It's up to you. I believe in "worth it" cheats....but this question made me think of thanksgiving at my house, and I realize most of it isn't "worth it" to me. I'll worry about christmas when I get there. One carb fest at a time
