John Candy was a Canadian actor who became a screen star in the U.S. and worldwide. He often played the role of the good-hearted, bumbling-but-lovable dummy -- he was the huggable uncle, the well-meaning oaf. Candy used his size to his comedic advantage but reportedly preferred not to talk about his weight or his health off-camera.
For much of his life, Candy was obese, carrying around 300 pounds on his 6-foot-2-inch frame. More troublesome, the man who would star in such hits as "Planes, Trains & Automobiles" and "Uncle Buck" was also a smoker.
In the 1990s, Candy quit smoking and attempted to lose weight, but his efforts to turn his health around seem to have come too late. In March 1994, a combination of years of poor lifestyle choices and heredity caught up with Candy, and -- like his father and grandfather before him -- the beloved actor died of a heart attack while filming on location in Mexico.
Next, one suspenders-clad media icon made a radical change in his lifestyle after having a heart attack -- and by doing so, has added years to his life.
