The Paleo Diet

Is there anything trendier than the Paleo Diet? Is there anything less recommended by dietitians?

People who seem to be reputable scientists and qualified doctors or nutritionists don't seem to think much of it.

Dr Karl Kruszelnicki doesn't think much of it.

Scientific American calls it "half-baked"

The current Wikipedia article calls it a "fad diet."

A Sydney Morning Herald article says there is no scientific evidence to support eating the Paleo way.
