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!)
Corrected. Although, it's somewhat hard replacing carbohydrates without also increasing the overall protein intake. There are probably variants of keto that fit, and variants that don't. There's apparently no catchy phrase for the overall "high protein diet" reference class.
Yeah, most people who do keto or other low-carb variants tend to eat a high-protein diet. But for fat-loss something like twice as much weight of dietary fat as protein is recommended along with sub-30 grams of non-fiber carbohydrates. And the medical keto diet, iirc, was something like 4:1 fat:protein. It's a lot easier to hit the protein macros than the fat macros.
