ELI5: All the stages of starvation up to death.
gpt
The first stage would be the conversion of any stored glycogen (form of stored excess glucose) into glucose. The second stage would be the breaking down of any stored fats in your body to provide for energy. The third and final stage would be the rapid muscle wasting once you do not have any fats left for breaking down. By this point of time, you may undergo cardiac arrest or simply die from diseases due to a weakened immune system. You're pretty much screwed at this point.
