“Intermittent fasting definitely and massively increases autophagy.  And thanks to our caveman history, it thrived.  In times of little food, lysosomes would race around the body looking for damaged cells, pre-diseased cells, and cells which weren’t doing much.  It would chop them apart - into their smallest parts - and either burn them for energy, or use them to repair other areas.  Simply, it would perform miracles without any outside help.”
