>Honestly, I think the best way to tackle it is not to outright ban the foods, but just add an excise tax. If we added a 10% tax to soft drinks, fries and pizza, it probably wouldn't make a huge difference to the average citizen's spending. It would be a 10% increase in your food budget if that's all you eat though. If you want to go crazy, add a program that lets you earn that back by doing healthy things, like riding a bike. We should probably do that anyways. If we want to reduce the amount of driving people do, paying them walk/bike places instead of driving isn't a bad system either.

The behavioral epidemic is defined by being irrational and not in the self-interest of the sufferers. How would a slight change in food prices lead to any change in behavior?
