Who You Callin’ Stupid and Lazy?

A number of readers have sent me links (thanks, readers) to a new study coming out of the UK that raised some eyebrows all across the Internet earlier this week. The headlines seemed to scream from everywhere “Do High Fat Diets Make Us Stupid and Lazy?” That, in turn, made me scream, so I took a look at this paper in the Federation of American Societies for Experimental Biology: Deterioration of physical performance and cognitive function in rats with short-term high-fat feeding

What I found was a less-than-impressive short-term study on rat performance that told me what I already knew: that it takes a while for new gene expression to really kick in when you radically shift diets. Just like some of you are seeing in the 30-day challenge. So what?

The Definitive Guide to Saturated Fat

It’s probably the one thing that prevents people from fully buying into the Primal Blueprint. Almost anyone can agree with the basic tenets – eating more vegetables, choosing only clean, organic meats, and getting plenty of sleep and exercise is fairly acceptable to the mainstream notion of good nutrition. The concept of Grok and a lifestyle based on evolutionary biology can be a harder sell, but anyone who’s familiar with (and accepts) the basics of human evolution tends to agree (whether they follow through and adopt the lifestyle is another question), at least intellectually. But saturated fat? People have this weird conditioned response to the very phrase.

“But what about all that saturated fat? Aren’t you worried about clogging up your arteries?”

Food Labeling Nonsense

I thought I’d forgo my regularly scheduled “Dear Mark” Monday post (or “Dear Readers” as the case may be) for a subject very near and dear to my heart: the constantly-evolving, ever-confusing ways of the food rating labelers. Whether it’s the AHA-approved red “Heart Healthy” stamps that implore overweight diabetics to stuff themselves with “healthy” whole grains or the mention of antioxidant and fiber content somehow making that sugary breakfast cereal good for your kids, packaged food distributors seem to love making outlandish claims that bear little to no fruit. It’s incredibly effective, though, for the same reason people will believe anything they hear on TV or uttered by someone with an official title. We’ve already got a far-reaching bunch of bureaucrats at the FDA deciding which macronutrients to highlight and which to demonize on the official nutritional labels that adorn the back of every packaged food item, so the natural next step is a mishmash of extraneous labeling that tries to make nutritional recommendations based on the FDA data (which is itself based on flawed, misguided, or even blatantly false science).

Primal Strength Training for Women: Not So Different After All

I knew they were coming, as soon as I hit “Publish.” I knew I’d get at least one or two comments from our female readers asking if last week’s muscle building post applied to them, too. You see, Conventional Wisdom has somehow drilled into our heads the silly notion that men and women are completely different species, especially when it comes to working out. There are definite differences – anyone who’s been married will be able to tell you that! – but that doesn’t take away from the fact that we’re all homo sapiens with the same basic physiological makeup. And so an outfit like Weight Watchers will push the chronic cardio, the ankle weights, and the step classes because of some underlying, self-defeating assumption that women aren’t “meant” to lift heavy weights. It’s insane, it’s preposterous, and it’s downright insulting. Men and women have different work capacities and different natural inclinations, but their bodies still work the same way.

Creative Visualization

Last week, I discussed the tangible effects of positive thinking. While we can’t quite say whether the connection between happy thoughts and good health/success in life are correlative or causative, it’s safe to assume a couple things: positive thinking is strongly associated with self-confidence and initiative, and all three seem to lead to good things for most people. There are no guarantees in life, of course, but there are ways to stack the deck in your favor. Eating the right foods and living in accordance with our ancestral past are two important, obvious (at least around here) ones; creative visualization may be another.
