Dear Taco Bell,
It has come to my attention that you have recently created a Drive-Thru Diet. You are clearly taking bold new steps to change the way Americans view healthy eating, so I am writing this letter to express my gratitude and enthusiasm and to offer insight for further improvement.
I first noticed your “Drive-Thru Diet” ad on a billboard outside of a childrens’ extra-curricular learning studio in west Los Angeles. Ever the inquiring mind, I visited Tacobell.com for some heavy research. I read Christine Dougherty’s 80 word story about losing 50 lbs over 2 years with Taco Bell. Very convincing. Then I watched TV personality Chris Rose interview four paid actors, and every single actor praised Taco Bell’s seven healthy Fresco menu items. Next I learned from registered dietitian Ruth Carey that some food choices are nutritionally better than others. These people clearly weren’t lying. The Drive-Thru Diet looked legitimate, so I decided to make a Frescolution. I hit a road block when attempting to fill out my pledge. The form required me to fill out “what I know.” I attempted to write, “I live a healthy lifestyle based on the 10 immutable Primal laws validated by two million years of human evolution…,” but Taco Bell overrode that with, “My idea of exercise involves the all-you-can-eat buffet marathon.” Oh well, I suppose what I know isn’t nearly as important as eating Taco Bell Fresco menu items.
Zero carb is getting (relatively) popular. A handful of valued MDA forum members eat little-to-no-carb, and several others probably imagine it’s ideal even if they don’t personally follow it. I wanted to address this because there seems to be some confusion as to how a zero carb eating plan relates to the Primal Blueprint eating plan. To begin with: I think zero carb can be a viable option for some, but highly impractical for most. If one had access to and ate different animals, all range fed and without pollutants, and if one ate all offal (and stomach contents) it’s possible to approach zero carb… but again highly impractical. If you really, really love meat and fat and offal, and get genuine enjoyment from eating nothing but meat and fat and offal, have at it. On the other hand, if you are looking for a wider variety – and gustatory enjoyment – of the foods you eat, zero carb may be unenjoyable, impractical, unnecessary, and at worst (if not done just right) downright dangerous.
Let’s take a look at just a few of the reasons why vegetables are a part of The Primal Blueprint:
Several months back, a major study comparing the nutritional value of organic food to conventional food made the rounds. Organic food, it found, was “no healthier” than ordinary food. There were no significant “differences in nutrient content,” and the study’s authors found “no evidence to support the selection of organic over conventionally produced foods on the basis of nutritional superiority.” Hmm, so there were “differences,” but they were “unlikely to be of any public health relevance.” Okay – even if I accept that the differences were unimportant, there was a major, glaring qualifier: “nutritional superiority.” Going organic, then, doesn’t suddenly change the essential composition of a plant. A grape remains a grape (small differences aside), whether you use artificial pesticides or “natural” pesticides. I buy that, and I don’t think many people who support organic are arguing that industrial organic farms produce purer, more “appley” apples than conventional farms. They’re simply wary of ingesting the artificial chemical cocktails applied to conventional crops.
Yesterday I challenged you to estimate my body fat percentage by looking at a recent picture. To be scientific about this little exercise I chose to reference as the correct answer the results of the “gold standard” hydrostatic weighing I had subjected myself to at the Malibu gym (it was actually a specialized truck that shows up once a year and performs the intricate and expensive underwater weighing tests for $60 each). 317 of you took a stab at guessing from the photo of me. It’s clear to me that many of you are quite good at estimating actual body fat levels (the average guess was 6.7%), but Gwen, anticipating the tenor of today’s post, took the prize with the closest guess at 12.5%… Ironically, that was also the highest guess of all and yet it was still a full 4 percentage points lower than what the actual “gold standard” test demonstrated. That’s right, my test score showed that I am 16.9% body fat. That’s 28 pounds of pure fat – if you believe the lab values. Even my wife Carrie tested lower at 13%. Am I really that fat? Probably not, but I went through this exercise to illustrate a point about which I will write today: that quite often, these so-called “gold standard” lab values are of little actual predictive value. Sometimes these tests are just plain wrong. And sometimes they can create far more problems than they solve. And if they are that far off when something is largely visible, what happens when they are dealing with more intricate hidden body chemistry? In this case, my jeans still fit loosely, so I really don’t care what the lab value was. I know the reality. But if I lived only by the lab values, I’d be inclined to start cutting calories immediately to lose weight.
It’s a nebulous term used by snake oil-salesmen to sell products cloaked in pseudoscientific terminology on late night television. Detox. If what they say is true, we apparently have millions of toxins constantly circulating throughout our body, permeating our cells, coating our digestive systems in a poisonous film, bogging down our organs. These toxins cannot be dealt with, nor reasoned with via the standard avenues of diet and exercise; no, they require the aid of special supplements and detox paraphernalia: magic herbs, weird colon-scouring clay mixtures, foot pads that supposedly suck the toxins directly out of the body, lemonade or juice fasting kits, liver flushes. They’ll often bring out a spokesperson who plays doctor well enough to convince your average Cheeto powder-encrusted insomniac that he or she needs this book or that colon cleanse to avoid obesity, cancer, disease, and depression. If you could just flush out all those toxins, you’d be doing great.
