Your mental model of eating-as-a-bucket is broken, but you're not to be blamed since everyone thinks that and it's the official advice from most (all?) governments.
The calories-in-calories-out (CICO) model is true in a thermodynamics sense but it's like saying that Bill Gates got rich because he followed the money-in-money-out system. It doesn't really help us explain anything about Bill Gates. Or another, more damning, problem is this: We say a child gets taller because of hormones but they get fat because of calories. If you think about it for a while you'll figure out something is deeply wrong with the model.
This is a deep subject with a lot to say but I'd start with 'Why We Get Fat' by Gary Taubes. Then read his other books, then read Dr Fung.
But to answer you first point directly: What I'm saying is that people thinking they are eating healthy and actually eating healthy are two different things. Usually they think they are but aren't in reality, and fasting can help in a long list of ways detailed in Dr. Fungs book on fasting (and many other places too, his is just a good book). You can also find people on /r/fasting on reddit with a lot more detail.
