Thileepan, Hunger and Remembrance: Why Do We Starve?

Starvation occurs in three phases. First, the body halts consumption of glucose, its primary energy source. Then, it scrapes away at fat deposits. Once those are depleted, it finally cannibalizes muscle mass to feed the brain. The body enters a delicate balancing act, substituting glucose for fat and eventually protein, until organ function is affected and results in death. The ultimate cause of death, in general, is cardiac arrest or the stopping of the heart. At its core, starvation is a process of desperate sacrifice.
