5.Kenneth Brumley

Kenneth Brumley was one of the heaviest people ever recorded in the history books.

He was featured on the Channel 4 Body Shock documentary "Half Ton Dad. He is a father of four and who weighed almost 468 kg or 1,035 pounds).

According to Kenneth Brumley's statements in the documentary, he had been bed-bound for four years. After he was accepted as a gastric bypass patient at the Renaissance Hospital in Houston, Texas, a fire crew had to hammer down a wall in Brumley's house to get him out.

At Renaissance Hospital, Brumley was treated by the team of specialists that treated Renee Williams, believed to have been the world's heaviest woman at the time. The first step in Brumley's treatment was a diet restricted to 1200 calories per day, which enabled him to lose 167.5 pounds (76 kg) in only 40 days.
