Hi Tamzy,
I share your pain with the non moving scales, and really commend you for remaining so committed, with seemingly little reward. One of my main problems is that I have gotten so frustrated after a week or fortnight of "perfect" eating, (and no movement), that I will lapse in to a day or so of really imperfect eating. (Repeat cycle endlessly) It's got me really down!
Recently I've been trying to convince my sister to believe that she can stop smoking for good. (She has failed many times, and thinks she is inherently "flawed" in this respect) I keep telling her that she has to believe she can-otherwise she won't/can't.
I have become so used to failing at weight loss, that now I need to believe in myself too.
What I've decided to do is keep eating sensibly- aiming at a maximum of 1500 cals a day, and to really up my excercise. I'm aiming to walk, on the treadmill, 200km per month. I know that the cals burnt display on the treadmill isn't really accurate, but this indicates that I am burning 100 cals per two km. So, if I can do 200km, (and this is about right), I'll burn an extra 10 000 cals a month, which has to result in some loss. (Otherwise my body is really, really unique!)
I started walking four days ago. I'm normally fairly fit, but haven't done very much for the last couple of months, (really due to frustration about my weight, which is silly), but to do the distance I'll have to spend more than an hour on average a day doing a quick trot. I'll let you know how I get on.
Hope you have a good one!
