My understanding: Lipolysis is activated by adrenalin and cortisol. You may burn some fat, but cortisol will break down lean mass to produce glucose.

Is there any evidence that an 18 hour fast—when nutrition is good, when there’s available fat mass, and calories unrestricted during eating window—causes body to break down lean mass?
I just don’t believe 1) that research showing damage of longer casts can be applied to a shortened daily eating window, and 2) that we need to be eating all day long to optimize our metabolism.
