What Happens When You Stop Eating?

The video explains the process of starvation, which occurs when the body lacks calories and nutrients. It describes three metabolic phases: glucose burning, fat burning, and protein breakdown. Initially, the body uses glucose for energy, then shifts to fat burning, entering ketosis. The brain adapts by using ketone bodies when glucose is scarce. In the final phase, the body breaks down proteins, leading to muscle depletion and potential death from cardiac arrest.

Describe the physiological process that occurs when the body switches to using proteins as a final reserve.
