Part of this problem, which as has been said, is complex, is the culture of snacking all day. I see babies and toddlers on the bus being given sweets or crisps to eat, it seems that children and adults have got into the habbit of earing snacks in front of the tv all day and evening. Also, the snacks themselves are often unhealthy - many contain corn syrup which gives a 'morish' taste so that it is hard to stop eating them. If only people ate fruit and nuts if they have to snack, they would soon realize the difference - you start to feel full much sooner and stop eating. What it comes down to is move more, eat less and eat natural, but there is no motivation - and now they claim to have found a gene that makes people addicted to food, so they have every excuse to blame it on this and stop trying. I think all snack type and luxury foods should be taxed so that they are at least double in price (eg a packet of 6 or 8 tunnocks caramel wafers and boxes of three walnut whips are each only £1 in poundland!).
