Which is the greater cause of fat people, the people themselves, or the food industry?

Jamie Oliver’s Food Revolution was on. The phone rang and I only caught part of an exchange Jamie Oliver was having with some mid-level mucky muck in the school district as to why he (Oliver) was getting so much resistance in getting in the school to do his thing. The official alluded to they (the district) didn’t want him to come in with his cameras and start saying the food was crap and that parents were slowly killing their kids feeding it to them. The district didn’t want parents told that chicken nuggets and nachos were making their kids fat that people were fat because they wanted to be fat. Whoa! Was he just letting food manufactures of the hook? That sounds like anyone who is fat cannot blame Häagen-Dazs, McDonalds, or any other fast food place, nor the food industry for loading food up with high fructose corn syrup; it was their own fault they were fat.

Here in the US where 60% of the population is overweigh to some degree, who bears more of the blame, those who make the food, or those who are eating it?
