Takeru Kobayashi prepares for the annual Nathan's International July Fourth Hot Dog Eating Contest the same way an Olympic athlete would prep for a track meet.
He consumes well in excess of 6,000 kilocalories of food per day to enlarge the capacity of his stomach, then works out for hours to use up the energy and develop a superhuman metabolism.
Training is meticulously stretched toward the date of the match to expand his alimentary organs to the limit, while the down time immediately after competitions is followed with advanced practice so more franks can slide down his throat the next time.
