Follow-up to: Boring Advice Repository
Many practical problems in instrumental rationality appear to be wide open. Two I've been annoyed by recently are "what should I eat?" and "how should I exercise?" However, some appear to be more or less solved. For example, various mnemonic techniques like memory palaces, along with spaced repetition, seem to more or less solve the problem of memorization.
I would like people to use this thread to post other examples of solved problems in instrumental rationality. I'm pretty sure you all collectively know good examples; there's a comment I can't find from a user who said something like "taking a flattering photograph of yourself is a solved problem," and it's likely that there are other useful examples like this that aren't common knowledge. Err on the side of posting solutions which may not be universal but are still likely to be helpful to many people.
(This thread is allowed to not be boring! Go wild!)
I'm not sure I deserved the heat here. I prescribed no particular diet and said nothing about weak willed scum. I'm of the tentative opinion that modern weight-control problems are just a case of human brains not being built for an environment of plenty. Even if it was simply that people on average can't keep their hands out of the pastry box, that's not a moral failing, just an outdated adaptation. It's worth fixing ourselves because it's now a maladaptation and evolution is too slow about fixing it.
What is going on? Is there a thread around here that you think covers it in useful detail? It seems to me that there must be some lower bound on food intake beyond which one can't help but lose weight -- otherwise you could eat nothing and still not lose weight, which seems spectacularly unlikely to me barring the aforementioned metabolic mutation.
It's not a rhetorical question; I have only mild difficulty controlling my weight, but my partner has a much harder time. (though both our weights respond to consistent food restriction) Useful information would be useful.
It has been observed that no fat people emerged from Auschwitz. But if some people do not lose weight below that level of privation, they don't stand much chance of doing so voluntarily.
