I also did my grocery shopping yesterday to see me through til Thursday when I fly back to the US. I found these fantastic little ready-to-cook meals in Tesco. They have really started to do some great foods there recently! For someone like me, who can't cook to save a life (no kidding!) they are a godsend. They are little foil trays in the uncooked meats section, and are all pure, basic ingredients. I got a chili beef strips pack and another one with chicken, peppers, tomatoes and herbs. No additives or anything, you literally throw them in the oven, or into a wok or pan, and they're ready in minutes! Two for £5 at the moment, so snap them up while you can. I live alone, and as I said, I cannot cook, so they are ideal for me. It also makes it so easy for me to plan what I'm going to eat for the week when I have packs like that. They generally contain 2 servings per pack, so £5 provided me with 4 days worth of dinners. I also got 800g of chicken for £6, which will serve me for 4 days of lunches at work, and I got a 1kg bag of frozen broccoli for 80p to go with all my meals! So 4 days of meals cost me £11.80 (about $18.8
I also braved the kitchen and made a recipe for marshmallow fluff that I found - I think it may have been on Linda's website. Cream cheese, cream, a little splenda and vanilla flavoring. It's the most delicious thing ever, and really tackles any cravings for something sweet, yet after a bite or two, I often find I've had enough.
I have my little lunchbox ready for my flight on Thursday. I'm trying to put together solid foods to go in it, as I can't take any creams or liquids on the flight. I figure chicken strips galore will see me through, although I may have to forgo any veggies, because from experience, they tend to get quite soggy in a tupperware box, and especially during 18 hours of traveling, I see this happening. It's only one day, and I know I'll just have to get back on track with my veggies the following day. I won't worry too much over going without veggies for one day in such circumstances.
I may in fact call the airline tomorrow and ask them for a diabetic meal for the flight, just so that I can have something made for me, and if there are veggies in that, I can eat something if it's legal. But at least I'll have food with me incase it doesn't work out.
Good plan? lol

Last time I flew I picked through the meal they giving you on the plane. There is always something in there that is semi edible.
Wish you good luck on the plane.
All is not over. You will do your best where you go and you will come back to more strict low carb eating when you can.
Also, sorry to hear about your fiance's parents. Sometimes I really get frustrated when the cultural practices of others stop progress. You'd think they would be understanding, but I guess they are looking at it from a different angle. If they don't have weight issues, they probably don't see foods high in carbs as a problem since they eat them every day. Have you tried breaking the diet down to them, in terms of exactly how it works and why? They could see an anti-carb diet as an assault on the way they live their lives. Just an idea.....you may have already tried that though. I hope you're able to find some way to make it work.
Also, I'm proud of you for having the guts to put up those before pics on your blog. That takes alot of courage. I had been tossing the idea around, not sure if it was such a good idea. Now I'm convinced that nothing but good can come of it.
Thanks for the inspiration.
Hope the flight goes well and all that follows.
