What are ketones? How does ketosis play into the Primal Blueprint? Did our bodies evolve to run on ketones? If not, why do they exist?
Ketones, to put it briefly, are compounds created by the body when it burns fat stores for energy. When you consume a diet very low in carbohydrates, the body responds to the significantly lowered levels of blood sugar by flipping the switch to another power source. The body converts fatty acids in the liver to ketones. Ketones, then, become the main energy source as long as blood sugar levels remain low.
So, you’ve decided to accept the Primal challenge. No time like the present, we say! To get you started we thought we’d share a few recipes in keeping with the “as if” challenge. No compromises or indulgences. It’s the PB diet straight up!
Last week we looked at what goes into our decisions to be healthy: the hows, the wheres, the whos and whys of consideration, of envisioning and finally of commitment. It’s a decision that puts ourselves at the core, we said.
Sometimes our path to that decision is smooth. Sometimes it’s a collection of fits and starts. Usually, it’s a little of both. Progress can come with slow, steady dedication and effort. But, oftentimes, there’s at least a few experiences when we put the pedal to the metal. Whether it’s an overwhelming, positive rush of internal motivation or the insistence of an external, swift kick in the pants, these instances of hyperdrive move us forward. And, yes, even if we lose some ground afterward, we’re changed for the experience nonetheless. We’ve felt that higher level of health, whether it be fitness, nutrition, life balance, etc. Even if we give up some of the result, we know how good it was, and mark our words, you’ll eventually crave it again and be back for more.
Reader Pete asked for some thoughts on the “Insulin Index,” a measurement chart similar to the glycemic index. While the glycemic index calculates the relative blood sugar rise induced by given foods, the insulin index evaluates the insulin response generated by 38 different foods.
The insulin index, which first made its appearance in a 1997 American Journal of Clinical Nutrition article, was primarily the creation of Susanne Holt, a graduate student at the time and now a doctor. Interestingly, Holt, her supervisory co-authors, or other researchers haven’t chosen to conduct further research to update the “preliminary” results of their insulin index study since its creation eleven years ago now.
The marathon. An epic struggle of the individual against his/her own body. A kind of “Mt. Everest” for athletic practice, it exacts a sizable toll on anyone who dares attempt it. (The first marathon man died after all.)
The seasoned athlete knows and respects the physical claim of a marathon, and it is substantial even for the best trained. But marathons are becoming increasingly popular in the last few years. Once limited to the athletic elites and diehards, marathons are now the stuff of social events and charity drives. We’re all for the social element of sport, and we’re suckers for a good cause like anyone. But this recent popularity has changed the face (and emergency support requirements) of marathons. While we believe that everyone’s got to start somewhere, we definitely believe this ain’t the place.
We know most of our readers here at Mark’s Daily Apple are well attuned to what it means to live healthily, but sometimes even the pros can make mistakes.
