I just walked to a meeting across the city, and back again! 6 miles! YAY!
I dunno if 'normalisation' is the best way to think about this issue with cultural perceptions of weight. I'm not denying it's a problem (I think Lolla was trying to help!), I just dunno whether it's as primary an issue as it might seem. At the back of my mind here, I'm a bit disturbed by people praising me for recognising I have a problem, because I don't think I really deserve that praise. I mean, it's lovely and supportive of y'all, don't get me wrong, but I really feel like a bit of a charlatan lapping it up. 
Let me put it this way. Based on my own failure to maintain a healthy weight, and my mindset in the time during which I gained radical amounts of weight (which is another way of saying "based on my experience of being a fattie"!!) the issue is less normalisation than headspace. If you have a whole bunch of shit kicking off in your life and you are the kind of person for whom food is comforting, it is easy to overeat. (I think it's also easy, in such circumstances, to start severely controlling food intake in various ways if you are the kind of person who finds that comforting instead! Neither is mentally healthy.) It is especially easy to overeat in bad circumstances if you don't have the resources to cook healthy food or are reliant on cheap food or on takeaways and ready-prepared food because you don't have any cooking facilities, or you don't have adequate cooking facilities. (I didn't have a kitchen for 4 months - or any space to cook in, due to building work!)
To diet - to commit to any goal - takes energy, and maintaing that energy takes some degree of stability. I'm able to face my weight issue head-on only because I'm basically very lucky. I'm at a positive point in my life right now where I have headspace, a reasonably stable environment, a supportive partner, and resources of time/money to invest (I have private counselling for abuse as a child, which has helped me to reach a place where I can do things like this, and I'm acutely aware of the number of people on NHS waiting lists who can't afford such a luxury). What I'm trying to say is that it is only as a result of this whole constellation of stuff, I'm able to face this problem head-on. I think it would have been very hard for me to do the same thing six months ago, when I was covered in dust and freezing cold and living on a building site. 
Another way of putting this: it is about will power, but there are sets of circumstances that make it much, much easier to sustain that drive, and sets of events that make it very difficult indeed.
Disclaimer (once again): I am no expert on any of this stuff - witness the marker on the scales!- but I reckon that encouraging people to care for themselves in whatever way they feel able is probably the right way forward. It's basically like FlyLady, but instead of shining your sink to remind yourself that you can tackle your entire house if you take it small step by small step, you do something small to remind yourself that YOU ARE AWESOME AND CAN DO THIS!
