It takes a lot to get banned from an all-you-can-eat buffet, but German triathlete Jaroslav Bobrowski did it.

Bobrowski scarfed down 100 plates of sushi at Running Sushi, an all-you-can-eat sushi buffet in Bavaria last Friday, according to Eater. And the impressive feat resulting in his permanent ban.

Even though Bobrowski has been a regular customer at Running Sushi, the restaurant didn't think it could continue to handle the cost of his eating habits. Eater estimates that he put away about 18 pounds of sushi in one sitting. Yikes.

“He eats for five people. That is not normal,” the restaurant's owner told the Passauer Neue Presse.

Bobrowski told German news site the Local that he was "stunned" upon learning that he was no longer allowed to dine at the restaurant.

Though the former body builder and current Ironman triathlete Bobrowski does follow quite the unusual diet. The athlete told the Local that he restricts himself from eating for 20 hours and then eats until he's stuffed to maintain his 10 percent body fat — and sometimes that means eating up to 100 plates of sushi.

Bobrowski has since become a minor celebrity in Germany and has been dubbed the "sushi man," according to the Washington Post. The athlete has also apologized for gorging himself at the restaurant and promises to be more mindful of his food intake in the future.
