It's Independance Day in the US of A. And to celebrate, Americans will participate in the time honored tradition of eating the most hot dogs in the shortest amount of time. This year's trophy goes to reigning champion Joey Chestnut, who managed to gorge on 68 hot dogs in10 minutes. Check out his pigging out skills in the clip below:
Just so you know, each of those hot dogs is equivalent to 290 calories, 17 grams of fat and 710 milligrams of
sodium. So 68 hot dogs would be equivalent to the amount someone on a 2,000-calorie-a-day diet would need in ten
days! As for what that kind of diet does to your body, Huffington Post reports:
A team of radiologists and gastroenterologists published the study in 2007 in the American Journal of Roentgenology. They had 29-year-old competitive eater, Tim Janus (as part of a National Geographic special), and a 35-year-old male control eater eat as many hot dogs as they could in 12 minutes, and then performed a series of stomach scans to see how both men handled all those dogs.
The regular eater finished seven hot dogs before he tapped out; the competitive eater ate 36 before the researchers said he could stop, they had seen enough. His abdomen, which had appeared flat before the eating began, now "protruded enough to create the distinct impression of a developing intrauterine pregnancy," the researchers wrote, while the average eater's stomach appeared just as it had before.
"Normally, the upper stomach expands to accept the food," Dr. David C. Metz, one of the co-authors of the study, and a professor of medicine in the division of gastroenterology at the Perelman School of Medicine at the University of Pennsylvania tells The Huffington Post. "The muscles relax to receive the food and that increases the volume of food you can put into it without increasing pressure." As pressure increases in the average person's stomach, they burp, experience nausea or even vomit. "Our hypothesis became that [competitive eaters] have the ability to relax their stomachs to such a degree that they can just eat and eat until you and I would be ready to pop."
Metz compares the average human stomach size to that of two fists, able to contain maybe a liter or so in volume at rest, he says. There hasn't been any research to quantify how much more a competitive eater's stomach can expand, but Metz offers the following analogy: While eating, the average person's stomach may expand to hold two or three liters, he imagines, whereas a competitive eater's may expand to hold six or seven.
There hasn't been any research into how competitive eaters come to react this way. Metz believes it's a combination of nature and nurture. Many are probably born with an innate ability to relax the stomach so they never seem to reach a point of feeling full, but they also probably train themselves to expand their stomachs even larger, he says.
So keep that in mind the next time you're thinking about participating in the competitive sport of stuffing your face. We're betting that Joey is not going anywhere near a hot dog stand anytime soon.
