He ate at the Waffle House for too many years... They take fat and grease... Add a little bit of butter, salt, pepper and then cook sausages, eggs, steak and other fatty foods in it... And viola... Heart Attack yack yack yack.
It's mostly the waffles and pancakes that lead to heart attacks. Predators are designed to eat steak and eggs for breakfast, and Waffle House has its fair share of predators.
