I've been on a ketogenic diet for a year now and sleep has been the biggest thing. I was a light, restless sleeper and I noticed very quickly how how much better my sleep got.

And by mixing and matching different research papers, any diet peddler/author/etc can make it appear as their specific diet is "backed by science" (when it's just a bunch of disparate papers in its favor, without context -- e.g. later responses to those papers, quality and reproducibility, papers that study the exact opposite claims and also work, etc).
The only real science is not in studies (that are a dime a dozen, of widely different quality, and most are shoddily done and discredited by later studies), but in what's accepted by the nutritionist/medical professionals as nutrition 101.
