FOOD

Without food, humans can only live so long. We need proteins, fats, carbs, vitamins, and minerals. When these aren’t consumed, the body starts to use its own tissue for fuel. While it’s very difficult to study starvation using traditional experiments because of ethical concerns, there is some data on its effects. It seems like a healthy male around 154 pounds should have enough calories stored in his body to live between 1-3 months. When researchers examine hunger strikes, however, people have died after 45-61 days. Many factors affect how long it takes someone to starve to death, but it’s clear that we need food or eventually we die.
