It sounds very impressive to say let’s make our new eco towns "fit towns" to tackle obesity, but many of these proposed image facilities are already available.

While it makes sense to provide more cycle lanes and safer walking routes to and from school, at the end of the day it is up to parents to decide how their kids get to school – and many prefer to drive them for various reasons.

I live very close to a primary school and I know where the youngsters live who attend. Our village is safe for them to walk and cycle to school, but the kids are often driven there instead, and for very short distances. I find it inexplicable.

One reason may be because a lot of kids watch TV before going to school, and then there is a mad rush to fly out the door. Mums need to rush off to work too. It’s a lifestyle issue for many. Will it necessarily be any different if they live in an eco-town?

That’s why there needs to be more focus on schools, it’s no good crying over spilt milk about the hundreds of school playing fields that have been sold off in recent years.

Is there any reason why those schools with playing fields can’t have mandatory jogging sessions for kids? At least half-an-hour three times a week. And those schools without them could perhaps provide exercise bikes and rowing machines which classes could take it in turns to use. This is inexpensive equipment and easy to use; this equipment could be adapted so it is suitable for their younger bodies. These are simple measures that could be very effective. They can start instantly too.

It’s interesting that Health Secretary Alan Johnson is modelling his "fit towns" around similar French schemes. My neighbour who travels to France regularly has noticed how they provide "activity" areas for teenagers to use up excess energy, and they are well used, while we do nothing like this for our older children. Not in my area, anyway.

*If our government wants to know how to build an eco town, here is a perfect example being planned in Abu Dhabi, where the emirate aims to build the world’s first zero-carbon, zero-waste metropolis.
