Why isn't there a fight against unhealthy food like is for drugs?

Color me crazy, but it seems things like fast food can be just as deadly when consumed in large amounts. I only say this because I was at a McDonalds drive through the other day and I see this family of 4 walking to the restaurant from the parking lot. The mother and father looked fairly large, and their son. Oh that poor poor boy. He was at least 9 years old and looked like he weighed around 250 lbs. There is nothing wrong with eating fast food every now and then, like on the go in such instances like I do sometimes. But I would not be shocked to find some people have that 3-5 times a week. So why isn't there campaigns like we have against the issues with things like tabaco? (I can't spell it right. it's late and i dont feel like using spell check lol) Did you know that in some cities they are starting a McDonalds delivery service? It's not McDonalds doing it, but it is some other company. Like wtf is wrong with America!
