thing is though, if someone wants to overeat and not exercise and is 'content' to allow their weight to creep up, and when its up, they are 'content' to stay that way - then that's up to them - they are entitled to do that and no-one has any right to tell them to sort it out.
Same as smoking, anorexia, etc etc - its up to them - its bad for them, but they're adults and its their choice - the problem lies when it begins to hurt others - as smoking does.
The problem is all this business of claiming its ok, and they're happy and love the way they look.
everyone is afraid to say anything for fear of upsetting someone - it promotes the idea that they can be that way and be totally healthy and fine so they don't need to address it.
remember the trend a few years ago to be bony thin? 'heroin chic' etc
i do not believe any fat person would pass the old 'magic wand' test ... that if a wand could be waved and they could be thin, that they would not take the offer.
