Should people be allowed to sue fast food restaurants for causing obesity?

If you are going to debate this topic, it seems that the status quo argument is easy. But the other side I would base on "what did they know and when did they know it".
As time has gone by we have learned that fast food places are poisoning us, and they are doing it so smoothly that we can't take all those health clams seriously that tell us that they are not serving us food but obesity, cancer, heart disease etc. The restaurants are clean and the food is served up so pretty and tasty how can we believe that it is bad? They claim as long as it is done in moderation it is not that bad, but it is. Just like smoking, is it okay to smoke in moderation, no it is not human nature to do some things in moderation, you either smoke or don't, your body will get addicted and you will smoke as much as your addicted body desires. It is the same for food. This fast crap has got to go.

This is the tact I would take if you are going to argue the contrarian side.
