A video released on the internet shows competitive eater "Furious Pete" going through Michael Phelps' daily diet of 12,000 calories within just 30 minutes.
Pete Czerwinski chowed down on an impressive array of dishes - three fried-egg sandwiches, three chocolate chip pancakes, a five-egg omelette, three sugar-coated slices of French toast, a bowl of grits, pasta with sauce, two ham and cheese sandwiches on white bread (with mayo), a pepperoni pizza, and cans upon cans of energy drinks.
The massive meal, which closely matches the Olympic gold medalist's alleged daily diet, comes to a whopping total of 12,300 calories.
Many YouTube users, however, say they're not completely convinced by Furious Pete's video, which was cut down from 30 minutes to four minutes, "so that you wouldn't get bored," Czerwinski explained.
"Look at the clothes in the corner, they are moved during the video, so it wasn't done in one take. sloppy editing ;)" the New York Daily News quoted user Kristaps Straumens as writing.
Others defended the Canadian consumer, who's achieved viral fame over the past several years for videos such as "Most Ferrero Rocher Chocolates Eaten in One Minute" and "Eating the World's Hottest Pepper."
"The guy has eaten an 8 pound burger. You think? he would fake this?' user xJDKx wrote.
Czerwinski's career as a competitive eater began in an unlikely way. He was admitted to hospital at age 16 for complications stemming from anorexia.
Over the next five years, he slowly recovered, building up his weight and getting fit through body building.
It wasn't until 2007, when Czerwinski sat down with several of his pals at a restaurant and realized that he could out eat them all in record time, that the idea of "Furious Pete" started to take form.
Since then, he's made a name for himself by eating obscure food and massive amounts of it.
