Mr. Chris Macey:

No. There are vested interests such as organisations like IBEC representing the food industry and helping to develop the policy around, for example, junk food marketing to children and the working out of voluntary codes and things like that. The commercial determinants we are talking about, which are the real drivers of obesity, are intense marketing and the high volume and availability of energy-dense foods. There is now a worldwide snack food industry worth $374 billion that did not exist in the 1960s. It did not exist before obesity became a problem. These are the issues that are driving the problem. All governments tend to do is come up with voluntary codes, which puts the personal responsibility back onto individuals and families when the environment just overwhelms them. You might walk past a shop nine times and not go in for a chocolate bar, but the tenth time you do. The other nine times do not count. We all do it. These are issues that are driving the problem.
