I would argue that it never really was about the reducing obesity rates. It is just another tax source for these assholes in office. All it does is screw low income people. Just wait for the fast-food/junk food tax that we will all eventually be paying. You can't compel people to lose weight by taxing the food they eat unless you want to raise it high enough that they cannot afford the food and let them starve. You want to see some results give people incentives to get off of their fat asses and get involved some type of physical activity.
