I have this weird little belief that is based on nothing scientific whatsoever that you have to actually want to lose weight before it will happen. I know that sounds weird cause of COURSE you want to lose weight, but I know for me, for a long time I 'wanted' to lose weight. But really, I just wanted other things, like to be acepted and be pretty etc. I always thought I really wanted to lose weight, but my brain just hadn't accepted the things I would have to do, it just wanted to put all the "my life sucks' feeling into one "because I'm fat" basket.
Then for some weird reason that is best left to psychotherapists to explain, I ACTUALLY wanted to lose weight. Not because I wanted to be accepted and pretty, but because I was sick of having aching joints and being unhealthy and bloated from rich foods etc and so I could ENJOY life.
I know a lot of friends wo "want" to lose weight and complain about how they can't do it, but continue to do things and excuse things that they know (being smart people) will not help them, like "I only eat a small amount of icecream for desert every day, and I only have a packet of lollies when I'm studying - which is every day etc"
I used to do the same - "It's ok if I don't walk home to make up my hour of exercise because I walked TO uni which is 15min downhill, and if I do walk home, I can take a couple of choccie bars to eat on the way for energy"
I guess it's a personal thing and you have to find the right time for you and be prepared for the long term changes that are required. And there is nothing wrong with getting into it SLOWLY and changing one thing at a time. Start with say reducing the size of the meals you currently eat and work with that for a month. Then introduce some exercise, then start shifing to more fresh fruit and veg and so on.
Sorry for the long speil, I just felt like typing an essay.

35kg lost. (November 2005 - October 2006)
15kg gained again (as at October 2010).
Back to the drawing board - Let's do this thing!
