Tarrare, a historical figure from late 18th century France, gained notoriety for his unending appetite and peculiar eating habits. He grappled with a rare medical disorder called polyphagia, which compelled him to incessantly hunger for and consume copious amounts of food, including non-edible items. Tarrare garnered public attention by devouring objects like corks, stones, and even live animals, once astonishing onlookers by devouring an entire basket of apples in rapid succession. Despite his astounding consumption abilities, his health rapidly declined, plagued by numerous complications stemming from his condition. The life of Tarrare remains an intriguing medical enigma, leaving numerous questions unanswered regarding the underlying nature and causes of his singular condition.

From ATI:

And the strangest part of all this was that he always looked as though he were starving. The young man barely weighed 100 pounds and he seemed constantly tired and distracted. He was showing every possible sign of undernourishment – except, of course, that he was eating enough to feed a small barracks.
