Yeah, I very much believe in general truths about this stuff, but I've definitely become a bigger believer in the "do what works for you" thing. In most cases the math/effectiveness stuff is accurate and applies to almost everyone, but as they say, the best diet is the one you stick to. What literally works and what "works" in the sense of being sustainable for a specific person are different things.
For example, I know on paper it's supposed to be very important to eat a good breakfast, but I find it very hard to do that and still stick to a good, sustainable diet. It seems to spur my hunger. I'm sure it's good advice with some sound science behind it, but for whatever reason I find it difficult to do, and I've found I can structure my day differently, and it seems to work, so I give the fact of it working priority over what's generally ideal for a non-specific person.
