Steven is almost forty, and his story can be traced all the way back to high school. It is my pleasure to share with you Steven’s long road to Primal living and the incredible result that followed.
If you have your own Primal Blueprint success story and you’d like to share it with me and the community please contact me here. Have a wonderful Friday, everyone, and thanks for reading!
I used to be a relatively fit guy back in high school and college… constantly staying active and spending a lot of time training in Martial Arts (which I’ve done for most of my life).
We eat while reading the newspaper. We eat while watching T.V. or checking email. We eat while packing the kids’ lunches (over the sink, Moms?), breaking up sibling scuffles, or trying to keep an unruly toddler from throwing every bit of her dinner on the floor. We eat while working or cleaning up or driving. Necessary multitasking, we call it. If we want to eat at all some days, we just have to work it into the mix. I know how it goes. I have my Big Ass salad at my desk nearly every day while I write. The pattern, however, has the potential to sidetrack our best goals, not to mention spoil a good meal. Researchers have increasingly found that the more noise, the more stress, the more distraction we face when we eat, the less satisfied we are.
The result of this constant distraction is easy to guess. We lose track of what we’ve eaten. We end up eating more. We enjoy eating it less. Subjects in a recent study, for example, were instructed to play a computer game while eating. Not surprisingly, they didn’t recall what they ate as well as subjects who ate their lunch uninterrupted. The game players also reported feeling less full and ate more at a second snack time 30 minutes later.
The following are both actual and paraphrased versions of questions I regularly get from readers:
If grains are so bad how can you explain the leanness and good health of Clarence Bass?
How do the Kitavans or Okinawans maintain good body composition despite a higher carb diet?
Mark, how were you able to maintain a low body fat percentage despite eating a half gallon of ice cream a day?
Why can my brother eat anything he wants and never gain a pound?
All of these examples seem contrary to what we say in the Primal Blueprint. How can they be explained? Are they anomalies? Tails of the bell curve? Is something else at work?
Insulin is an old, old hormone. Evolution has preserved its structure across hundreds of millions of years and hundreds of thousands of species. Fish, insects, reptiles, birds, and mammals all secrete insulin with fairly similar amino acid arrangements (insulin from certain species of fish has even been clinically effective in humans), so, clearly, it is a vital hormone. But insulin gets a bad rap in our circles. Why? With metabolic syndrome laying waste to the citizenry and with insulin playing an undeniable role, it’s difficult not to be soured on this hormone.
And yet we need insulin to shuttle all sorts of nutrients into cells, like protein and glycogen into muscles. It’s there for a reason, so to demonize it is misguided. It’s chronically elevated insulin and insulin resistance – you know, the hallmarks of metabolic syndrome – that are the problem. You might have noticed a softening stance on carbohydrates around the paleo and Primal blogosphere. I think it’s simply an acknowledgment that in healthy people with healthy glucose control and healthy insulin responses who engage in glycolytic activity, starch is fine in measured amounts. And if insulin increases to shuttle that starch and protein into the insulin sensitive muscle cells, so be it. That’s why it’s there.
But not everyone (anyone?) lives a perfect Primal existence. And even if you did an understanding of how insulin works and what foods and behaviors affect it’s production should be high priority. Especially for the millions of people immersed in the modern, industrial lifestyle, with deranged metabolisms from years of poor eating habits (i.e. most of us).
A few studies caught my attention this week, not for being all that surprising or groundbreaking or even new, but because they jibed with something I’ve been mulling over: physical activity in old age.
Studies: the first and second. I grouped these together because they largely deal with the same thing. The first, actually a review of a couple dozen separate studies, discusses how basic physical capability seems to predict mortality later in life, while the second focuses entirely on the predictive ability of a person’s walking speed. This is redundant to anyone who’s ever felt a euphoric post-workout rush or the satisfaction of completing a physically taxing task, but judging from the number of people who make endless loops in the parking lot to score that sweet spot by the door and avoid empty staircases in favor of crowded escalators, we are in the minority. Things like grip strength, the time it takes to rise from a chair, the ability to balance on one leg, and walking speed were strong determinants of mortality. The death rate was 1.67 times higher in folks with weak grips, 2 times higher in those who were slowest to rise from the chair, and 2.87 times greater in people who walked at the slowest pace. Most of the studies reviewed were of older subjects, but the physical activity markers were predictive in young people, too. The walking study found that normal gait speed was an indicator of mortality with predictive power similar to BMI, smoking status, blood pressure, and other chronic conditions.
