Human fat is substantially more complex than olive oil. Also he survived on more than his fat. He also survived on his skin, some muscle tissue, organ tissues, etc. Research shows increased autophagy during fasts like the one described at your link. During a fast whole organ systems shrink as old senescent cells are destroyed and their nutrients recycled. The oddest thing about reading the comments here is that people are dismissing the words of someone who has spent the better part of a decade in formal education in medicine, and a large part of his professional career focusing on weight management.
