"[A]n imbalance of appetite hormones brought on by sleep deprivation alone can trigger an intense craving for foods high in fat, salt, and sugar... Sleep loss essentially disconnects your brain from your stomach, leading to mindless eating. It deceives your body into believing it's hungry (when it's not), and it also tricks you into craving foods that can sabotage a healthy diet.

Recent research on the brain shows just how lethal this mix can be on the body, encouraging what's called conditioned hypereating, which short-circuits the body's self-regulating mechanisms, leading to chronic body chaos and energy loss."
