I have needed to lose weight all my life and have never been driven until doing exactly what Maddysmummy has just explained...making mini-goals. This is the process that they use at weight-watchers as well.

I have to admit I also work-out with a personal trainer at the moment but that really just helps your fitness and toning but the big weight loss comes from eating properly I've found. My mini-goal last year was to lose 8kgs by xmas time (am very over-weight & had a total of 30kg to shed) and I managed to lose 12kg instead. At the moment my mini-goal is to lose 5kg within a month and I'm already 1kg down. Smaller goals are easier to manage and process through your mind than larger ones which can seem daunting and unachievable.

I also find the more exercise I do, the more motivated I am to eat properly because of the hard work it took to do the exercise in the first place. Exercise can be anything, as long as you're moving your body and doing more activity than you'd normally do....walking, swimming, riding bike, walking to shops, stretching exercises indoors etc. Have you got any stairs in a park around your surrounding area? The biggest motivator to not over-eat after doing a work out for me has been 139 steps I was made to walk up and now run up. When I first did them I walked and had to stop several times all the way up but I can now run up them four times!!! So after finding that hard to do and being proud of myself for completing even the times I walked up them, I didn't want to un-do all the work I'd done by coming home and eating it away. Over time this has motivated me more and more to eat properly and lose weight.

Anyway, hope that helps. Hope you find the motivation you are looking for soon. Sorry for the long-winded response.
