Humans, like all animals are designed to store fat when food is abundant and use those fat stores when food is scarce. You can survive with no ill effects (just some fatigue) as long as you have body fat. Some people run out of fat in a few days and other after many weeks. Once the fat stores run out, your body will start to burn muscle and you will begin to die. Your body will tell you when it runs out of fat. Listen to it.
