Have you tried like, you know, a regular healthy, balanced diet? Real foods, mostly plants, not too much? Just funny you didn't include that. As a side note, the Mediterranean diet has been ranked the top diet by nutritionists several years running.
From what I've read, Mediterranean means something sorta along the lines of "natural whole foods, not much meat, lots of olive oil nuts and salads" -- and this is vague nutrition advice which can apply to almost any non-exclusionary diet.
