The big issue as I see it is where the line in the sand should be drawn on this kind of law making... successive governments have legislated for more and more and whilst some of it makes sense, some just seems to be a ridiculous amount of overkill, done because 'they can' [the cigarettes hidden is one I think falls into this category, don't want to get into that different argument now, but its just one example of one those things that seems stupid and will have minimal desired effect, pretty sure there are better alternatives/education] - this American law seems to be in that category - as already mentioned, it will have little, if any effect as those that want that much fizzy drink will just buy two if taking away, or keep refilling if in restaurants. Is the next stop to ban refilling, and make store owners legally responsible for only selling one at a time? ...and thats where my line in the sand point comes from, its that such regulation snowballs in the hands of power and takes away all sense of responsibility from those that most need to get one!
Going to Neils point about healthier alternatives.... yes, buying absolute 'raw materials' for cooking/eating IS usually cheaper, even in the supermarkets [and I am talking now about buying a couple of pounds of standard spuds instead of a bag of chips, not buying the super organic, hand fed from birth with caviar spuds that ARE expensive] but not everyone has the time or indeed even ability to cook from scratch daily. Generally those are also the people that want their small amount of free time to be exactly that, free time, not to spend hours in a kitchen cooking enough healthy meals to last through the next week of work. 'Convenience foods' are needed in our current way of life, but I do also believe they could be much healthier than they currently are whilst still maintaining a reasonable cost.
Finally, isn't this about educating everyone about moderation? I like having a McDonalds breakfast, but I have about 1 a month, that way it remains a treat and enjoyable and in the overall scheme of things is doing me little harm - frankly if I had to have one every day, I would be sick of them within the week, but not everyone is like that. So that takes us straight back to responsibility then....

Yes, I can argue myself round in a total circle and do so on a regular basis :bonk:
