Sorry my mistake Petula.
Another thought, as I was assessing my environment, even a simple thing like the home environment should be assessed as it makes a massive difference - where you live, how you live.
Kitchens - simple equipment for cooking more veg, banishing frying or deep fat frying, they may want some decent cookery books or show them some websites.
Home - If people watch a lot of TV, to stop using the remote, sitting on a high stool at home so you are more likely to get up and not sit for hours, putting the computer on a shelf on the wall, having a dining table. Using stairs etc.
Local facilities - Where are your parks, showing someone the most convenient way to exercise.
Routines - helping people deal with clutter, having a fresh kitchen to cook in, a clear floor to exercise on.
Work - once you are overweight it's hard to get work, people associate it with laziness and dysfunction. Helping with that might also be good.
The thing is you can't bombard people with this stuff they might need coaxing through it a bit, which is why I think support will help. Most people know what they should be doing, they just can't for some reason. I don't think anyone wants to die an early death on purpose.
This is the one chance the NHS have to make a difference by offering a holistic approach, I just hope they do that and don't offer another one size fits all solution that most people can't work with.
