His performances involved the consumption of metal, glass, rubber and other materials. He disassembled, cut up, and consumed bicycles, shopping carts, televisions, and a Cessna 150, among other items. The Cessna 150 took roughly two years to be "eaten", from 1978 to 1980. He began eating unusual material as a teenager, at around 16 years of age, and performed publicly beginning in 1966. Lotito had an eating disorder known as pica. Doctors determined that Lotito also had a thick lining in his stomach and intestines which allowed his consumption of sharp metal without suffering injury.
Lotito claimed not to suffer ill effects from his consumption of substances typically considered poisonous. When performing, he ingested approximately 1 kilogram (2.2 lb) of material daily, preceding it with mineral oil and drinking considerable quantities of water during the meal. He said, however, that bananas and hard-boiled eggs made him sick. It is estimated that between 1959 and 1997, Lotito "had eaten nearly nine tons of metal."
Lotito's method for eating all of this metal was to break it into small pieces before attempting to eat it. He then drank mineral oil and continued to drink water while swallowing the metal bits. This acted as a lubricant to help the metal slide down his throat. He also had no problem "passing" his unusual diet.
He was awarded a brass plaque by the Guinness Book to commemorate his abilities. He consumed it as well.
Lotito died of natural causes on June 25, 2007, ten days after his 57th birthday. He is buried at Saint Roch Cemetery in Grenoble.
