When we don't eat, our bodies start to break down stored fat for energy, which can sustain us for a pretty long time. It's like having a backup power source that kicks in when our main energy source (food) is gone. But, how long can we rely on this backup power before things start to go downhill?
Well, the answer depends on a few factors, like our weight, activity level, and overall health. For example, if you're a pretty active person, your body will need more energy to keep going, which means you might not be able to survive as long without food. But, if you're sedentary, your body might be able to coast for a bit longer.
So, what's the record for the longest time without food? It's a pretty crazy story - in 1979, a Scottish man named Angus Barbieri fasted for 382 days under close medical supervision. That's like going without food for over a year! Of course, this is an extreme example, and not something we'd recommend trying at home.
