20 people for 14 days on one diet then 14 days on another. I don't see how this is a terribly illuminating study. This is not sufficient time or statistical sample to extrapolate to, well, really anything. What confounding factors were unrevealed by the small sample size? What structural problems are introduced by such a short time span?
We need to either collectively start ignoring these studies on somebody's 5 fraternity brothers over a weekend, or we need to start demanding more people, longer time horizons and better controls for confounding factors. I'm pretty disappointed to see NPR hocking this crap or Cell publishing it.
