Is obesity a burden on society or a burden on the individual?

Previously, I’ve asked this question: How can we ban fast food from the breakfast/lunch/dinner table?

On my blog : www. banfastfood.com I write against fast food as the primary choice for children and families.

Some people who responded to my first question spoke about the constitutional rights of people to eat what they want and that other people’s eating habit shouldn’t matter to others. Statistics prove that most people who eat fast food and the majority of the obese are working class individuals. Those are people who cannot afford health insurance; people who will crowd emergency rooms for emergency care; people who are less educated; people who will not be productive members of society because they will die of heart disease, diabetes, high blood pressure, etc… Healthcare cost will continue to rise and the price of health insurance with it.

We regulate tobacco, street drugs and prescription drugs because drug addicts are a burden on society. Isn’t obesity?
