I'll be honest. I get together with my non-Orthodox family and friends and enjoy Thanksgiving, food and all. I do try not to overdo it and not eat too much. I am usually successful in that regard. I do eat some turkey, but even on Thanksgiving, I eat far more vegetable dishes and casseroles than I do flesh meat. I allow myself one piece of dessert and enjoy coffee and conversation afterwards. I do not have to worry about leftovers because I am from a big family and I am always invited to eat with them as a guest. I never host the Thanksgiving meal in my home. I travel to a relative's house for it, and usually take fruit as a gift for the hostess. As soon as Thanksgiving is over, I immediately return to the discipline of the Nativity Fast. Today I had a Nativity fast breakfast of Russsian rye bread and black cherry preserves (no butter) and some black coffee. I find all sorts of foods to eat during the fast that are both nutritious and that taste good. I rarely loose any weight during the Fast because I don't exercise enough. But I really don't go hungry or get dizzy from lack of nourishment. I eat peanut butter, rice, textured vegetable protein (use it in vegan chili), bread, pickles, sauerkraut, oatmeal, almond milk, apples, cabbage, peppers, onions, beans etc. I actually feel BETTER in the fast. I feel lighter, my joints don't hurt as much, and I seem to have more energy. However, it took years of being Orthodox and experimenting with the fast and with food and recipes to find the right balance.
