I'm not sure what you are trying to say. Are you suggesting that I advocate for people going through a thermodynamics class so they "get it"? Traditional education isn't very effective even for some trivial matters so I wouldn't dare to propose that. As far as I'm concerned, the vast majority of people cannot learn much of complex science and there is nothing wrong with that. And I wouldn't advise learning about thermodynamics just to solve a diet/exercice balance problem. In fact, I do the opposite. I tell people interested in the matter about various strategies they can use to control their caloric input and other strategies/motivations they can use to get a minimum of exercice. But that's largely irrelevant, that's not the point. The problem is the various gurus who spit pseudo-science on the matter, pretending that CiCo isn't a thing and pointing the finger at various other things (sometimes with a sprinkle of truth to make things confusing). There are many nuances in nutrition but if you don't get the basics right, nothing good can happen. And the gist of the matter is that every human needs to find a strategy that works for him to control his caloric input in relation to his energy expenditure. One way to do this that is extremely effective is to build an intuition on how many calories most common foods are "worth" but also how much various activities/exercices spend. It takes effort but it is pretty simple and once people have the intuition on the matter they can more easily regulate the intake or exercice more, depending on what's easier/more successful for them. It doesn't necessarily solve some psychological disorders (like addictions and compulsive eating to regulate emotional state) but at least it gives a "roadmap" and a pretty accurate picture on how/why. I have no idea what you are trying to say but it really isn't that complex of a problem. Humans being what they are make it more complicated than it needs to be.
