Consuming a 5-kilogram hamburger and a plate of wedges in a single sitting is more than most people can stomach, but it’s all in a day’s work for one of Japan’s ōgui consumers.

Ōgui eaters are ordinary people who have the extraordinary ability to consume vast amounts of food. They can even attempt to devour as much as 10 kilograms in a single meal, stretching their stomachs to maximum capacity for a slice of online fame.

The online aspect is important to understanding why anyone would go to great lengths to eat so much food. It follows a popular South Korean activity on social media called mukbang in which YouTubers live stream themselves devouring calorie-laden meals in a bid to attract millions of views and subscribers.
