1 gram of uranium has about 20 million calories, what would happen if one eats 1 gram of uranium?
I’ve heard the human body can only get energy out of carbon chemistry – fats, sugars, proteins and so on.
(Edit to add: not even all carbon chemistry is accessible for us to metabolise; we can’t digest gasoline for example)
To get 20 billion calories out of a gram of uranium you need it to undergo fission in a nuclear reactor, which the human gut is not equipped to either cause or benefit from.
I also read “If it was pure uranium, you would die. those calories they are referring to are not food calories. you would gain no weight above the gram you ingested. you would quickly start to lose weight, actually.”
Not sure if these quotes are true. Essentially people are wondering that since uranium has a lot of calories wouldn’t that help in gaining weight or putting muscle? Or if it’s 20 million calories can you gain hundreds of pounds just by eating it?
The correct answer and explanation is:
Short Answer:
Eating 1 gram of uranium would not provide usable energy for the human body, and instead, it would be highly toxic and radioactive, leading to severe health effects or death.
Why Can’t the Body Use Uranium’s Energy?
The “20 million calories” in uranium refers to its potential energy if used in a nuclear reactor, where fission reactions split atoms, releasing enormous energy. However, the human body relies on biochemical energy from digesting carbohydrates, fats, and proteins, not nuclear energy.
Even if uranium were chemically digestible (which it is not), our cells lack the necessary mechanisms to extract nuclear energy. Just like we cannot digest gasoline for calories, we cannot break down uranium into usable energy.
Health Effects of Ingesting Uranium
If someone eats 1 gram of uranium, several dangerous things happen:
- Heavy Metal Toxicity: Uranium is a toxic heavy metal, damaging the kidneys and liver. It gets absorbed into the bloodstream, poisoning organs and causing failure.
- Radiation Exposure: Natural uranium emits alpha particles, which are relatively weak externally but can cause severe DNA damage internally, leading to cancer.
- No Weight Gain: Since the body cannot metabolize uranium for energy, it won’t contribute to weight gain. Instead, uranium poisoning causes weight loss due to organ failure and sickness.
In short, uranium is not a super calorie source—it is deadly poison. Instead of gaining muscle or fat, eating it would lead to serious illness or death.
