Its the other way around for me - I always think of myself as age early 30s / size 12 and get a REALLY big shock when I catch a glimpse of myself in a shop window or mirror if I'm not prepared for it - finding a 50 year old / size 22 looking back.

I don't know why but my internal image of myself has always been me at about a size 12 but I think thats why, even though I've gained weight, I've found it hard to get motivated to do anything serious about it because I never think of myself as being 'big'. Over the years I've just drifted from one faddy diet to another losing a few pounds and gaining a few pounds more. I'm not daft, though, I know that I need to buy a size 22 but I still flick through the size 12s and 14s first when I'm out shopping for clothes.
The way I look at it theres no miracle way of losing weight apart from chopping off a body part, so there's no point in expending energy getting stressed about it. What I can do is to put that energy in to planning healthy low fat/low GI meals and snacks and taking regular exercise then the excess weight will come off in its own good time.
