No because people make there own choices and if they choose to eat poorly and cause bodily harm to themselves than so be it. People would argue that in some cases people cant control there weight which is fine but they still should not be eating fast food. I like to think of it as natural selection if dumb people make bad choices than they should suffer the consequences, business should not be liable for this only others that care about them like family and friends to help them get back on course.
