Was Heart Attack Grill Menu Responsible for Blair River's Death?

Did the Heart Attack Grill menu ultimately cost the restaurant spokesperson, Blair River, his life?  River was the main spokesperson for the Heart Attack Grill which featured some rather hefty burgers on the menu, leading many to think so.

The restaurant in question mocks good nutrition, and if it had been a popular national chain, would have likely taken a lot of heat away from McDonald's. Heart Attack Grill even gives preference to those who weigh over 350-pounds and calls their diet a special health prescription, using a fake doctor to pitch the concept in their video.

The Heart Attack Grill menu features items with "bypass" in the name, but Blair River died of pneumonia.  However, a recent LA Times report has an interesting take.  They have noted that at least one published study indicates obese individuals may be more likely to catch pneumonia.  Additionally, obesity can increase the likelihood of coronary heart disease, type 2 diabetes, various cancers and stroke.  So the argument will continue as to whether River's death is due to his poor nutrition and size, or simply due to a bad case of pneumonia.

A commercial seen below shows a humorous look at the Heart Attack Grill and its main spokesperson, although this shouldn't be taken lightly.  River's weight was nearly 600-pounds and that often leads to a variety of health problems.  Eating foods known as the "Quadruple Bypass Burger" might give someone a popular reputation, but it could also cause a shortened lifespan if its a person's main diet.
