The idea of "hey, this strange thing worked for me, and I don't wholly understand all parts of the system but it seems to have some results" is pretty much the core of what "hacking" is, right?
I'm not saying that you don't have a valid idea here, but that doesn't meet with my understanding of the term. I mean when I say I'm a hack piano player, I mean that i can get by but am not classically trained. When I say, this fix for my problem is a hack, I mean that it's not a well engineered solution, but rather that it's a functioning (albeit perhaps ugly) solution.
I can also say that it's a good thing that I didn't apply that when I started working with computers or I would never have gotten to the point where I understood the systems well enough to bend them to my purposes regardless of the intended behavior.
And that doesn't even touch the question of what "intended behavior" might mean for a biological entity which isn't "designed" in a way that has an intended use.
The underlying assumption when hacking is that if you don't understand the internals of something that's ok, but you can rely on understanding the interface, and your manipulation of the interface is skilled enough that you can get the results you need.
In this case, we don't even remotely understand the interface or manipulating it.
Consider the case of two kinds of users operating on some kind of interface that is unfamiliar, say, MS Word.
One class of user will consult a manual and try to find the right answer, or perhaps will call an expert.
Another class of user will just start pushing buttons to see what happens, because they have a rough familiarity with the system even if the specific interface is not well understood.
It's that second class that I am thinking about when I think about how "hackers" operate.
In that case, I get that it's dangerous to mess around with a system whose internals you don't know about... but at the same time, there is a kind of fantasy that somehow other folks have a privileged knowledge of what our bodies do.
Personally, I quit wheat and dairy (and reduced my alcohol consumption) because it's a specific tree allergy season here. I have a couple possible accounts of why this is working (because I believe that it is) but I don't really understand the interface or even what I am manipulating when I alter my diet like that... I just know that I can breath, whereas historically I have terrible allergies at this time of year. Feel kind of like a hacky solutions... it's not an engineered solution, that's for sure.
