Further to last week’s item under this heading, it isn’t just the dietary pattern which means you never have a really empty stomach which would have been so unusual throughout most of our evolutionary past. Surely, having a bloodstream suffused with high quality nutrients absolutely all the time would have been another thing which would have occurred rarely, if ever, during hundreds of thousands of years of hunter-gatherer ancestry.
It seems to be open season for speculation about this new dietary idea, because we lack the body of scientific evidence that would support a claim that any particular way of doing it is better than any other. All that can be said with confidence is that a wide variety of eating patterns which result in the stomach being empty – and therefore not releasing fresh nutrients continuously into the bloodstream – for periods of about a day at a time, all seem to result in weight loss. What’s more people trying out these patterns report that they are surprisingly easy to maintain, that they do not cause ravenous hunger the next day, and that they seem to be associated with feelings of well-being and clear-headedness. And possibly also with improved memory.
All this is of course so subjective that anecdotal reports (and even one’s own experience) must be treated with the greatest caution. But they are effects which would be eminently testable in controlled conditions. Just so long as nobody comes up with a ‘right’ way of doing it which destroys the complete flexibilty which is its greatest attraction.
