When your body gets too little fuel, it begins to go into starvation mode. In starvation mode, your body is going to try and conserve energy. If you've ever been on a restrictive diet and suffered from head aches, fatigue, loss of energy, insomnia, a rumbling stomach, or irritability, you have experienced your body's starvation mode. This not only makes life extremely unpleasant and potentially endangers your health, but can make you too tired to exercise and cause your body to start burning muscle mass in addition to fat. To top it off, in starvation mode, you are most likely to run into a weight loss stall, as your body desperately tries to hang onto stored energy.

But abnormal adrenaline secretion during the night can also cause insomnia and nightmares.
