The Battle of the (Mainstream) Heavyweight Diets

“One of the symptoms of an approaching nervous breakdown is the belief that one’s work is terribly important.”

Bertrand Russell

The following video is of a lecture given in January 2008 by Christopher Gardner, PhD, assistant professor of medicine at the Stanford Prevention Research Center, and focuses on the largest and longest-ever comparison (as of that time) of a selection of  four popular diets studied under real-world conditions.  The diets in question were the Ornish, Zone, LEARN (i.e., the diet recommended by most academics and the USDA — the food pyramid we all know and love), and, last but not least, the Atkins diet.  The 311 participants, (all pre-menopausal, overweight women) were divided into 4 groups, with each group having been provided 8 weeks of  “in-depth” nutritional training using the representative flagship book for each diet.  Training was led by a dietitian who preached the magnificence and utter superiority of each group’s assigned diet.  All of this makes for an interesting study because of the real-worldliness of having these participants attempt to “follow the book” for themselves (subsequent to the 8 weeks of brainwashing, that is).

An additional interesting twist here is that Professor Gardner is (was?) a twenty-five year vegetarian, who, having come into the study with a heavy, pre-conceived bias, admits (and you have to give him kudos for this), that his long-standing notions of the efficacy of a vegetarian diet may have been completely unfounded.

Of course, we in the Paleo community would’ve loved to have seen the Paleo way represented in this study — but hey, the fact that Atkins was included is a monumental step in itself.  In fact, Dr Gardner does bring up the subject of the Paleo diet toward the end of the lecture — to the hoots of snorts and laughter from what I can only assume was a very learned and open-minded audience (really, no sarcasm intended).  Whatever; I’m in the pharmaceutical business — all those snorts and all that laughter sounds like job security to me.

Anyway, I do think this lecture is well worth the time investment.  You may not learn anything new about diet, per se, but you’ll certainly pick up quit a bit in the way of diet psychology.  Keep in mind as you watch just how well a Paleo diet would have fared in this trial.  Remember, you’d have had 8 weeks to teach someone the whys and hows of the Paleo way; 8 weeks to stage for, and transition through, the carb Jones; 8 weeks of social re-conditioning and n=1 individualization tinkering.  What book would I have “preached”?  Well, personally I’d have opted for Primal Body, Primal Mind, by Nora Gedgaudas.  For homework, I’d have assigned selections from Taubes’s GCBC.

A few interesting things to keep in mind as you watch:

Dr. Gardner’s chart presentation on the spread of obesity throughout he US is powerful.  We all know these facts, yes — seeing it presented in this fashion, though, brings this static information “alive” in a profound way.

Notice as well all the maddening, tunnel-visioned viewing of the study’s statistical results data through the old “calories in, calories out” prism.  It’ll make you want to jump through the screen and remove the good doctor’s blinders.  It reminds me of the story of the two fish, wherein one fish asks the other, “what’s this stuff water I keep hearing about?”

Interesting, too, is the behind the scenes view of what it required to land a study grant, and how painfully long the wait is between grant acquisition and the release of actual study findings.  And add to this all of the Political wrangling — both in academia and in the government realm — that must be traversed.  It’s mind numbing.   If it were not for the internet allowing the immediate connection of like-minded folks, all of whom are actively engaged in n=1 studies of “Paleo science”, Paleo would yet to even have a fair hearing in the world of nutritional science.

Kudos, then, to us — for actively advancing the Paleo science.

And a big round of thanks are in order to the Balanced Existence website for having re-excavated this find.   You can read their interesting commentary on the lecture, here.

Sit back and enjoy.

In health,

  1. Highly interesting, Keith.

    Will watch the lecture later tonight.

    Just an update: I have added raw milk to my diet since last week(1 liter or 1/3 a gallon after my 3 heaviest workouts of the week)and feel very good. Very different from the pasteurised crap I used to drink in my first few years of training by the gallon … ugh that made me feel bloated, even after just half a liter.

    On heavy training days I eat 4 times a day(with perhaps a few teaspoons of almond/hazelnutbutter in between), on resting/active recovery days 2-3 times a day, trying to fast a little more each time.
    I have subtracted one piece of fruit from my daily intake on the days I drink the milk, to compensate for the added carbs.

    Scale is climbing slightly. So far so good.

  2. The thing that is interesting about the Atkins individuals is that they trended toward a more paleo macro profile as time went on.

    The thing that interests me the most, as is unfortunately a take home point if you’re not willing to tinker and adjust, is that every diet averaged a regaining of weight as the year went on. Net loss overall but the “lows” were not maintained. Statistically they’re still better off than the average american; kudos to them for that.


    • I wonder how much of that re-gain had to do with (1) “fat fright”, (2) the dreaded carb jones, and giving in over time to social conditioning, (3) not eliminating grains as a carb source, and (4) poor workout choices (i.e., “long and slow” as the way to go).

  3. Hey, I’m glad you enjoyed my commentary on the professor’s presentation. As I say in my article I found his comments about Paleo and the reaction of the crowd somewhat idiotic.

    I knew I had to comment on this in my article to clear up what he said because co-idiots on YouTube were taking up his comments and using it as the basis of an argument that people on Paleo ate less calories because there weren’t many things available to eat on that diet.

    I could knock myself out from my own forehead slapping. Talk about suspending intelligence in order to make an argument.


    • There really is no answer for dim-wittedness like that; I mean, combating it with intelligence is just futile. Reminds me of the old saw of teaching a pig to sing; it’ll just frustrate you, and annoy the pig.

      • There really isn’t is there? Another good saying that involves pigs is to not bother wrestling with a pig because all you get is dirty, and the pig likes it. I feel that applies to this sort of situation nicely.

        I’m interested in having you write a guest post(s) for my website if you’re interested? Hit me up at stephen at balancedexistence dot com if you’re interested.
