When fasting is prolonged, the body will turn to other energy sources for fuel in the absence of glucose. It does so by breaking body fat down into fatty acids, which are then converted by the liver into ketone bodies. Ketone bodies serve as a backup energy source when glucose is not available.

Over time, your body will start to show signs of deficiency in those nutrients that you can’t absorb.
Aug 6, 2015 · But things get really dire after 72 hours, when your brain decides it needs more than just ketones to survive. This is when your body starts to break down its own proteins so that it can use their amino acids to form glucose. This means your body literally cannibalises itself and eats away at your muscle tissue just to stay alive.

A 2013 study reported that persons who reduced their daily calorie intake by 40 percent for one day felt significantly hungrier the next day. Additionally, undereating increases cortisol production in the body.
