I normally think in terms of maintenance as something I will come to later, when the weight loss is finished. This time I want to be sure about what my long-term strategy is, because there are so many ways to go. Do you rely on clothing fit? Have a regular weigh-in? Weekly? Monthly?
What about food, OK so there has to be a long-term change to have results, but there are ways and means. For example, when you are on maintenance you can decide to 'budget' for treats within your calorie allowances or plan so that if you are going for a special event you can have a big platter of food and work it in. Alternatively you can decide that you aren't going to have these things at all and that if you are invited to a big event you will decline, organise a special menu, leave half, etc.
Have you chosen your long-term strategies? What will you do about weighing in? What will you do about snacks, treats, meals out, your favourite vice? Perhaps you are at your maintenance weight and you've tried one of your old favourites and it's disgusting now! And where did you add back the maintenance calories? Bigger portions? More food groups? Bigger snacks?
The only strategy I have so far is to be sure to include a lot of variety in my dieting to make sure I've got a variety of meals for when I reach maintenance, I've usually had a very small 'safe list' of meals that I repeated and repeated till the weight came off, rather than have enough variety to realistically keep me going. If I don't take this time to mentally adjust to not going back then I will go back.
