Michel Lotito (b. June 15, 1950) is a Frenchman, born in Grenoble, famous as the consumer of undigestables - Monsieur Mangetout.

Lotito's performances are the consumption of metal, glass, rubber and so on in items such as bicycles, televisions, a Cessna 150, and smaller items which are disassembled, cut-up and swallowed. The aircraft took roughly two years to be 'eaten' from 1978 to 1980. He began eating unusual material while a child and has been performing publically since 1966.

Lotito does not often suffer from ill-effects due to his diet, even after the consumption of materials usually considered poisonous. When performing he consumes around a kilo of material daily, preceeding it with mineral oil and drinking considerable quantities of water during the 'meal'. He apparently possesses a stomach and intentine with walls of twice the expected thickness, his digestive acids are also unusually powerful allowing him to actually digest a certain portion of his metallic meals.
