How is this ban going to reduce obesity? Unless they limit the amount of food that people can consume while eating out, I don't see how this is going to help.
Sugary drinks are fattening, but so are a lot of other things like fried foods, mayonaise, ice cream, butter, etc. When people are eating out, let them decide for themselves. I can see something like this being implemented in a school setting, but not in deli's, fast food places, restaurants, etc.
