Dear Mark: How Much Glucose Does Your Brain Really Need?

LowRes2We now know that the oft-repeated “your brain only runs on glucose!” is wrong. I’ve mentioned it before, and anyone who’s taken the time to get fat-adapted on a low-carb Primal eating plan intuitively knows that your brain doesn’t need piles of glucose to work, because, well, they’re using their brain to read this sentence. Obviously, you eventually adapt and find you have sufficient (if not much improved) cognition without all those carbs. That said, some glucose is required, and that’s where people get tripped up. “Glucose is required” sounds an awful lot like “your brain only uses glucose” which usually leads to “you need lots of carbs to provide that glucose.” And that’s the question today’s edition of “Dear Mark” finds itself attempting to answer: how much glucose is required?

Let’s get to it.

8 Reasons Why You Act Against Your Own Better Judgment

donutWe all make poor choices against our better judgment. It’s kind of what makes us human – the tendency to actively and willfully make decisions that will result in unfavorable outcomes. Sure, the candy bar tastes good, but you know you’ll feel awful after eating it. Yeah, that blog is fun to read, but you know you’d be much happier if you finished that essay for class first. And yet five minutes later, a candy bar wrapper sits, emptied of its contents; your molars house fragments of nougat and sport a caramel sheen; light nausea approaches; and you find yourself wading knee deep through comment sections, MS Word window minimized. What just happened? Why did you do those things that you told yourself you wouldn’t, that you warned yourself against, and whose negative ramifications are already coming to fruition – just as you predicted?

Is Honey a Safe(r) Sweetener?

honey 1I pride myself on making the Primal Blueprint an easy lifestyle to follow. If you were just starting out, you could easily read a few articles, do a couple hours of research, and start making positive changes to your diet, exercise routine, sleep schedule, or daily life immediately. You could ditch grains or replace some chronic cardio with weights or switch to grass-fed meat, and even if you did nothing else, you’d have made a significant improvement to your life and eventually your health. I often receive thank you emails for putting together a program that Internet-illiterate grandmas and grandpas can get into and actually understand. That said, sometimes things get a little confusing.

Like with honey.

The “Asian Paradox”: How Can Asians Eat So Much Rice and Not Gain Weight?

eatingriceHow the Primal community loves the concept of a dietary paradox. How we eagerly point to its various manifestations as supportive evidence for our way of eating, living, and moving. You know the French Paradox and how it confounds the experts. To mention all those smug surrender monkeys with their brie and their butter and their duck confit and their Gauloises and their seeming imperviousness to heart attacks is to make Dean Ornish binge on bran and pull out tuft after tuft of frizzy hair. And then there’s the lesser-known Israeli Paradox, which attempts to answer why Israelis have skyrocketing rates of heart disease despite a skyrocketing intake of “healthy” omega-6 fatty acids. In its wake, Walter Willet might be found weeping into a mug of safflower oil. There’s even an American Paradox – those who ate the most saturated fat had the least coronary heart disease – that had the minds of researchers thoroughly boggled.

How to Fuel a Marathon

sweetpotatoes3Having yielded to those of you who still insist on running a marathon, yesterday I offered a training strategy that gets you the best results with the least amount of damage. Today’s post is about fueling a marathon – what food to eat and when to eat it. It’s not solely about race day nutrition, because if you just focused on what to eat the day of the race, you’d be missing out on a lot (and you’d likely have problems finishing, or at the very least your performance would suffer). It’s about what to eat while training, a few days before the race, and the day of the race itself. This is the stuff I would do if I had to go back and do another marathon with my current knowledge. I might tweak things slightly if I was trying to make the Olympics, but for the average, relatively fit Primal dude or gal who wants to check this off their bucket list? This is the perfect way to fuel your efforts. And this works equally as well for those of you who think a century ride (100 miles on a bike) might be in the cards.

First, let’s examine what to do while you’re training. What do you eat? How much of it do you eat? Low-carb, high-carb?
