This is such a good question. How do you keep going? It is the whole trick really isn't it, consistency. Thanks for posting this, you are not alone, or maybe it's just you and me !
Firstly well done, well done, massive well done for what you have achieved, it is a superb achievement !! Give yourself a huge pat on the back. You inspire me big time, thanks.
Secondly, why are you saying you can't do it when you have such amazing proof that you can, because you have! The scales, as they say, do not lie. So it just isn't true that you can't, you can. The truth is you are finding it difficult, which is a totally different thing. I know when I start struggling my mind plays tricks on me and I can come up with all sorts of apparently credible reasons to break the diet. So I try to take some time to remember why I am doing it, go back to how I felt before I lost any of the weight, imagine how I would be feeling today if I hadn't lost any, which is very scarey .[ the photos too are a very good reality check, I feel sad for myself when I look at them and proud now that I care about myself] Yambabe is a big advocate of the pack to pack approach and I find this quite helpful when the going gets tough [ which is surprisingly often !] You have said you don't want to give up, so that is the bottom line, you must have what you want because you deserve it and it is possible and in your power to give that to yourself [ unlike winning the lottery] you just need a bit of help and refreshing of your resolve. Your weight loss shows you know how to do it, drag out all the thoughts you had when you started the diet and use them again, distract, keep busy, prepare yourself mentally for mealtimes, take control, decide what you are going to do and stick to it, empower yourself to just chuck, chuck chuck any extra food away, and celebrate your skill and the weight dropping off as you do, slam the breaks on in your mind over your craving, picking is soooo not worth it. That is the truth, remind yourself of that, bin it , look in the mirror and tell yourself you love yourself, you are clever, care about yourself and in control, take care of you, your body will repay you with years of good service that you will enjoy. I expect you already feel massive benefits from that, I know I do. Face up to your picking, it's just a silly little mistake, easily rectified in a trice, a learning point on the long term plan, don't stress about it, let go of it, try and relax and realise it's easier than it currently seems in your mind, examine it[ are you a it stressed about something else]take care of your emotions and tell yourself you can beat it, just one meal at a time, soon it will be an old habit you don't do anymore. So rather than trying really hard NOT to do something , focus on positives, what you ARE doing, you are a new you, congratulate yourself after every time you don't pick, say out loud to yourself, well done me ! re-enforce positive messages, it really does help. Maybe write down a little message of congratulations, love and support to yourself and read it every day and feel good about yourself and what you are doing. Keep surfing that weightloss victory wave, as Quak says, it's all for YOU, do it for YOU. Good Luck, we are all there with you xxxxxxx
