I think it is getting worse and the years go on and will continue to do so.
When I was a school child there were hardly any overweight (podgy, fat, tubby - however you want to put it) children around. We all played out at breaks and lunch time and ran our selves ragged, then played at the park in the evenings, after shcool activities all consisted of sport and you wouldn't dare take a note in to get out of PE.
Now kids are far too into computer games and technology to do some good old fasioned playing and they eat far too much rubbish and parents are far too soft in letting them get away with it. There is no excuse for it, parents should be concerned and Tony is right ... it needs sorting out sooner rather than later and needs monitoring, there is no point in waiting until you are ill before doing somthing about it when prevention is a lot easier and cheaper than the cure.
My personal belief is that we are in a lazy food culture and some people can't be bothered to cook a healthy meal choosing instead for a quick fix or a takeaway.
I have just holiday'd in the UK for the first time in lord knows how many years and the number of kids, already overweight and in some cases obese, sitting eating, and in most cases stuffing their faces, with bag loads of sweets, chocolate and junk food made me feel very sad to be honest.
It's not nice ... people think they are being kind by letting kids eat what they 'like' ... but in the long run it is everything but kind. It is unfair and only the kids will suffer.
