In the fall of 1898 Sir William Crookes (right) gave his inaugural address as the incoming president of the British Academy of Sciences.   Unlike the typical such speech, this one was prophetic and alerted the British populace for the first time to a real and growing problem.  And the populace began to worry, because Sir William was the Al Gore of his day, alerting his country (and the world) to a looming danger.

Other than prophesying disaster, however, there were a few notable differences between Sir William and Al Gore.  First and foremost, Sir William was a true scientist, not a bloated former politician with no technical training.  He was the inventor of the predecessor of the tubes later used in televisions and radios and had discovered and added thallium to the periodic table.  The second major difference is that his worries were valid.  They weren’t concocted from a gibberish of people hoping to cash in on the public’s fears of an imaginary melting of the earth, but were born of a serious concern for the continued success of the human race.  Or at the very least, the continued success of the people of Great Britain.

Sir William Crookes was deeply (and rightfully) concerned that the world would soon run out of the ability to fertilize crops, and that, as a consequence, millions would die.  At that time Britain was importing guano (the droppings of sea birds) from islands off the coast of Peru and from the nitrate fields of Chile, but those sources were finite, and Sir William realized they would at some point run out.  (He predicted sometime in 1930 as doomsday.)

Paleolithic paintings from Lascaux cave in southern France

I imagine most readers of this blog would expect a group of subjects to do better on a Paleolithic diet as compared to a standard American diet, but there are few studies actually making the comparison. One was posted yesterday in the Advance-0nline-Publication section of the European Journal of Clinical Nutrition that shows subjects following a Paleolithic diet made major metabolic changes, and made them rapidly.

Before we get into the study, let’s make sure we’re all on the same page when we discuss the Paleolithic diet. We we say Paleolithic diet, what are we really talking about?

At Fat Head the Movie premiere

A couple of years ago I got an email from a guy named Tom Naughton asking if he could come interview me for a movie he was making that was supposed to kind of be a counterpoint to Morgan Spurlock’s Super Size Me! I hadn’t seen Spurlock’s film at the time, but I knew enough about it that I was wary of anyone who wanted to make a film maybe showing fast food places in a positive light.  I wrote Tom back and suggested we talk.  Once he had me on the phone, Tom was able to make me realize that his film was not pro fast food, but was pro personal responsibility.  And that it was pro low-carb, since the diet he went on and lost weight on eating at nothing but fast food restaurants was a low-carb diet.

He came to visit with all his movie making paraphernalia and we set to the interview, which I wrote about in a previous post.  We kept in contact over the intervening years, and I watched multiple versions of the film as it evolved and got better and better with each new iteration.  Finally, Tom called to tell me Fat Head was finished.  MD and I attended the premiere of the movie a few weeks ago (we are pictured above with Tom at said premiere), and I can tell you that folks were laughing their heads off.  It’s a very funny movie made by a guy who is a professional comedian.  Along with being funny, however, the film is exceedingly thought provoking.  I can’t imagine anyone who might be anti low-carb watching it and coming away feeling the same.

There is an old joke that goes something like this:

Question: What is Mozart doing in his grave right now?
Answer: De-composing.

The same question could be asked of the living right now who are working hard on their diets and seeming to go nowhere body weight-wise.
