When we don't eat, our bodies start to break down stored fat for energy, a process called lipolysis. It's like our body has a built-in backup generator, where it uses stored energy to keep us going. But, just like a car running on fumes, we can only keep this up for so long before we start to feel the effects.
The record for the longest fast is held by Angus Barbieri, a Scottish man who went 382 days without eating in the 1960s. Now, I'm not saying we should all try to beat this record, but it's pretty mind-blowing to think about how our bodies can adapt to such extreme conditions. And, fun fact, Barbieri's fast was supervised by doctors, who monitored his health throughout the entire process.
So, how does this compare to other living things? Well, some animals, like bears and squirrels, can go months without eating during hibernation. And, on the other end of the spectrum, some bacteria can survive for years without food or water. I mean, talk about extreme survival skills!
