Well.... Playing devil's advocate here but...

I think that selling a product that is so high in fat could be construed as knowingly selling a dangerous product. In America, the leading cause of death as far as I know is still heart disease. Whether it's brought on by excessive fat/cholesterol or smoking or a combination of the two I'm sure is not known.

In this fella's case though I'd say his argument will be simply that thse fast food chains knowingly sold a dangerous product and share some of the culpability for his current situation.
