If you're writing a post comparing the experimental evidence for four different diets, that's not "Rational Dieting", that's "Optimal Dieting".

Isn't that as wrong and misleading as using Rational Dieting? Wouldn't Optimal imply that this is the very best way to diet when the article is actually on 'Comparing evidence for for diets'? Same as how 'Rational Dieting' carries an implication that your post discusses the cognitive algorithm for dieting, as opposed to four contributing things to keep in mind and thus you should use 'Four Biases Screwing Up Your Diet' for a title, doesn't Optimal imply the wrong thing? Seems to me like you are committing different fallacies (or errors) when you are trying to fix the previous fallacies (or errors) committed due to the misuse of the word 'rational'.

And, if you want to get technical, optimal implies both an objective function to measure the solution by, and a proof that no solutions are superior. "Optimize your diet" seems better than "optimal diets," but even then "four proven diets" seems superior to both of those.

"A directed search of the space of diet configurations" just doesn't have the same ring to it.

I don't know, that title seems pretty awesome to me. (But my research is also in direct search methods, so...)

Depends. If it's an article describing how to evaluate different diets to pick the optimal one, then it is indeed an article about optimal dieting, even if it doesn't identify an optimal diet.
