There are people who eat 10,000 calories every day, like Britain's strongest man Eddie Hall or Olympic swimming legend Michael Phelps. They need these calories because for them, intense exercise is practically a full-time job.
Nope… Your body can't digest this many calories in one go.
In order to reach 9,000 calories a day, you'll need to focus on getting “the best bang for your buck” in terms of calories per meal. Dietitians call foods with a lot of calories per bite "calorie-dense." These foods will allow you to take in more calories without feeling too stuffed.
Consuming such a low amount of calories can cause your body to go into starvation mode, which can slow down your metabolism and lead to a loss of muscle mass, which can make it harder to lose weight in the long term.
Most of us would not be able to sustain a 900-calorie diet plan for more than a week, let alone for a whole month without medical support. Rapid weight loss is also not healthy, and its results are hard to maintain over time.
As a professional eater, Jesse Freeman can devour five kilograms of food in one sitting, and claims to eat up to 30,000 calories a day.
1 gram of Uranium is roughly 20 billion calories. But “calories" here mean the amount of energy an object contains, not the energy you can obtain from it. So you won't gain much — only 1 gram — and probably get radiation poisoning or cancer and die.
Former World's Strongest Man Eddie Hall would eat 20,000 calories in a day again despite the vile side effects of the food intake. During his time competing, Hall would eat 15,000 calories worth of food each day but was forced to add an extra 5,000 calories to his usual diet to complete the challenge.
Duyff suggests the “rule of 10” to estimate the base number of calories an adult needs. The rule assumes 10 calories per pound of body weight to fuel the body's normal daily functions. An active adult — one who exercises daily or at least regularly — can take in more calories.
The Food and Drug Administration (FDA) use 2,000 calories per day as a standard for nutrition advice on food labels. However, the number of calories that someone needs may be higher or lower than 2,000 per day. Indeed, the number of calories a person needs will vary depending on their: age.
Generally, the recommended daily calorie intake is 2,000 calories a day for women and 2,500 for men.
However, other studies show that while consuming 1,000 calories a day may result in significant weight loss, most people cannot sustain it and often experience significant weight regain . The reasons include regaining lost muscle mass and increased appetite. Also worth noting is that the human body can adapt.
A gram of fat (like oil) has 9 calories. 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.
A normal healthy person should consume between 2,000 and 2,500 calories per day. A 5000-calorie diet is closer to the recommended daily calorie intake. Eating 5000 calories per day won't cause you to gain weight, but you should consider increasing your calorie intake if you're overweight or obese.
Overeating can cause discomfort in the short-term but eating too much long-term can lead to weight gain, along with other metabolic issues such as insulin and leptin resistance, high triglycerides and increased risk for obesity and diabetes.
Hudson described his average daily diet as consisting of two boxes of sausages, 1 pound (0.45 kg) of bacon, 12 eggs, and a loaf of bread for breakfast, four hamburgers, four double cheeseburgers and five large portions of fries for lunch, and three large ham steaks or two chickens, four baked potatoes, four sweet ...
Starvation calories are an intake of fewer than 600 calories per day, however; any caloric intake below the recommended minimum doesn't provide the body with the fuel it needs to function properly.
In addition, consuming as few as 800 calories daily may not give you the energy you need for daily living and regular physical activity, especially if you eat the same foods every day. Talk to your doctor or dietitian to make sure you get the nutrients you need while on a very low-calorie diet.
While 1,200 is the minimum level of calories that the average person can survive on without the body going into starvation mode, that does not mean it is healthy, she told The Independent.
Understand how and why diets often fail
Calorie restriction can lead to slower metabolism, increased hunger hormone (gherlin) and decreased satiety — or 'feeling full' — hormone (leptin). You not only feel hungrier, but you're less likely to feel full or satisfied by what you eat.
