The key difference between intermittent fasting and autophagy, however, is that people typically fast for weight control but attempt to trigger autophagy for disease protection. This is a sensor of intracellular energy, which is known as adenosine triphosphate or ATP. Fasting for 12 hours a day is pretty easy because most of that time is spent sleeping. Defects in autophagy-related genes, however, are easier to study and have been associated with the onset of certain human illnesses, like certain forms of cancer, neurodegenerative diseases (like Parkinsons and Alzheimers), metabolic diseases, and autoimmune diseases.
