Today is going to be a bit of a long Dear Mark blog post. I got some great questions from you guys. First, I cover three questions regarding the insulin spike and carb load from vegetable juicing. Next, I discuss the place of G_BOMBS, or the “perfect nutritional combination” of greens, beans, onions, mushrooms, berries, and seeds, in a Primal eating plan. The blood sugar response to meat is next, along with a followup question about how dietary fat affects the glycemic response to eating carbohydrates. Finally, I field a question regarding the utility of artificially increasing one’s propensity to sweat during workouts by turning the air conditioner off. Does it hurt? Does it help? Find out below.
Sometimes, weight loss slows. Sometimes, what worked amazingly well before, stops working quite the same. Although this can be scary, frustrating, annoying, or all of the above when progress slows, stops, or requires new input to continue like it was is ultimately okay, because we are an adaptive species. We can change things up, shift stuff around. Physiological processes (among which weight loss and metabolism can certainly be counted) are never linear – that’s partly what makes all this stuff so endlessly engaging.
Today, I revisit a strategy for overcoming these lulls in weight loss induced by low carb: carb (re)feeds. They seem counterintuitive, sort of, especially if you’ve had success restricting carbs, but hold you opinions until you read on. I think you’ll find it enlightening.
We 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.
We 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?
I 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.
