I've been maintaining for about 10 months and while my weight stays pretty stable around the target I set. I don't panic if I'm a kilo up or down one day to the next. Three eggs and two thin slices of toast for breakfast every day (Morrisons sourdough seems to do the least damage). Poached one day, boiled the next, scrambled if I can be bothered... Sometimes just bacon and eggs (no toast), sometimes proper all guns blazing fry up. I don't often eat lunch (never really feel the need) and I'm quite sinful with supper. Mcdonalds once a fortnight (ask them to put two burgers in your Quarter Pounder with cheese then just don't eat the bun - balance the whole thing on the big tomato slice - good and messy). Pizza once a fortnight with no restrictions, Chicken Caeser salad (obviously - haven't we all become experts at that), nicoise (which I love), chicken-garlic-sag balti once in a while (no rice... but you CAN have the onion bhajis), haddock from the chippy (don't eat the batter) and NO CHIPS !!
Snacks are salami and chorizo, pork pie (don't eat the pastry), those posh glass jars of anchovies, any cheese I fancy on water biscuits and dark chocolate (one square after dinner). Don't forget to keep your metabolism up with a small coffee after food... But apart from the chocolate I never (like NEVER) eat sugar unless it's very well hidden. I never eat any pasta, any other bread other than toast at breakfast, rice, potatoes or things like crumpets or muffins. From day one I found the low carb thing really easy but I'm someone who honestly enjoys a savoury rather than sweet diet. The hardest thing for me is if (for work or social) I have to go to an Italian restaurant.
Oh (and here's the mad one) I drink two bottles of 12% Italian red wine every night and have ever since I can remember !
I walk about a mile every day with the dog and have the average life of a single parent with three school age kids (10/13/17) but no gym, no weights, no swimming - no nothing.
Honestly I think the protein from three eggs in the morning is the key - I never get hungry at lunchtime and although I break a few rules I only eat fairly small meals in the evening (but I have NO science or diary/record keeping to back this up).
I've LOVED losing a lot of weight really quickly this way and then keeping it off for about a year so far with a diet I honestly enjoy. I also really like finding new ways and new recipes to get good flavours and good food into my life without the carbs.
Good luck maintaining :)
