That's quite a lot, and depending on your age, height, weight, etc., you'd need around 10 hours of intense exercise to burn it off. Practically, eating so much food is likely to make you feel nauseous and extremely tired. You might even have no appetite for the next day or two.
Rapp tweeted that he burned 10,521 calories Saturday, beginning his day-long workout at 4:30 a.m. and finishing at 9:09 p.m. He biked 125 miles, with 103 coming in one ride, swam 1.25 miles, hiked four miles, ran three miles and had a short workout. It came as part of the #10kCalorie Challenge.
Not only will the digestive system be overworked, but the body's detoxification organs like the liver and kidneys will also be alarmed. Under so much stress, these are some of the physical risks of trying the 10K calorie challenge. Probably the most obvious side effect of eating this many calories is gaining weight.
In order to eat 100,000 calories you would have to guzzle down over 11 liters (or nearly 3 gallons) of pure oil. It is physically impossible to eat 100,000 calories in one day.
For every 3,500 calories, the general rule of thumb is it adds a pound of weight to your waistline — assuming it's not burned off. So a full 100,000 calories could potentially add up to 28 pounds. But, rather than put their hands up, it seems many are shifting the blame.
People may turn to 1,000 calorie diets when they are desperate to lose weight quickly, such as before a vacation. While adults could follow this type of diet relatively safely for a couple of weeks, it is not something that doctors advise for extended periods.
The basic element of Elvis' daily food intake was a 30-cm long bread roll, stuffed with bacon, peanut butter and strawberry jam. Each one had 42,000 calories, and in his final days, he ate two of them per day, together with little midnight snacks of hamburgers and deep-fried white bread.
And in the '70s, a doctor actually put Presley into a medically induced coma for weight loss. By the time of his death, Presley was consuming about 100,000 calories per day.
There are many factors that go into determining your calorie needs. Your age, weight, height and activity level all play a role. According to dietary guidelines in the United States, adults 21 years old and older should consume anywhere between 1,600 and 3,000 calories per day.
There are 7,700kcals (kcal=calorie) worth of energy in 1kg of fat. That means in order to burn 1kg of fat, you must have a calorie deficit of 7,700.
You don't absorb every calorie you eat.
On average, roughly 95% of the calories you put in your mouth are absorbed during the digestive process. However, as you may have noticed the last time you took a number two, not every parcel you eat is entirely digested.
A big meal with calorie content over 1000 takes almost three to four hours to digest, a smaller meal of 600 calories will take a couple of hours. Similarly, a snack worth 300 calories will only take an hour to digest.
So, 10000 calories is approximately equal to 1.30 kilograms.
So now we've got two World Records for calorie-burning: 1169 calories per hour; and 19,000 calories per 24 hours. If you'd like to include a 7-day record, that would be about 11,000 calories per day per week, to judge from Kouros and the RAAM rider. Wanna go farther?
On top of that, Elvis ate these kinds of foods in large portions. Since so many of the foods he gravitated toward are considered "comfort foods," there are a number of reasons he may have eaten so much of them. One reason could be that they reminded him of his mother's cooking.
Elvis Presley
Presley's fondness for peanut butter and banana sandwiches is well established; however, bacon is not mentioned in all accounts. A book about Presley and his mother, Gladys Presley, though, says he had "sandwich after sandwich of his favorite—peanut butter, sliced bananas, and crisp bacon".
On August 16, 1977, Elvis Presley died of a heart attack. He ate four scoops of ice cream and six chocolate chip cookies during his final meal. It is well known that he had an inconsistent eating habit throughout his life.
It's no secret that Elvis, like all the best people in life, loved eating. He had a particular penchant for meat, peanut butter and fried foods, meaning his diet was incredibly rich.
Health issues
The King was also covered in sores. Throughout his final months, Elvis gained a whopping three and a half stone after he decided to lock himself away in his bedroom. Presley demanded cheeseburgers and feasted on the fast food staple day and night, which eventually left him at 25 stone.
Elvis didn't like regular pizza; he demanded specialty pies from Coletta's Italian Restaurant in Memphis. Barbecue pizza. Say what? Yep, Coletta's invented barbecue pizza pie in the 1950s and it was the King's favorite.
When you cut your food intake to 1000 calories and below, your body is forced to break down muscle so that it can provide your body with energy since your food intake does not provide it with enough energy. This results in a person losing their muscle and affects their metabolism as we've just highlighted above.
This phenomenon is called “starvation mode,” and while your body isn't actually starving, it will naturally hold onto whatever calories it receives in an effort to help you maintain your energy balance.
