How do we combat the obesity epidemic?

[MK]

Make healthy food cheaper. A lot of obese people are poor and can only afford the food that leads to obesity.

Also, if the cheap food had less of the fattening material (but not enough to distract from the taste) it could work.

This.  I don't know where most of you are from , but in the south go to any dollar store or similar chains and you will notice junk food is super cheap.

Also tax the hell out of places that refuse to comply with healthier choices.
