The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate...
Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...Tell Me More
At the heart of every building is its framework. That latticework of timber, concrete or steel is what holds the entire structure up. Without it, there’d be no building at all. I think of that phrase some people use when they look at a house and declare, “It’s got good bones.”
Considering how essential bones are to our existence, it’s surprising how most people take them for granted. A lifetime of neglect can suddenly reveal to us just how sensitive and integral this living framework is. Yet, there’s so much more to this truth than we commonly assume.
Sure, the skeletal system provides the stable foundation upon which our muscles, organs and fascia are constructed. But that’s just the half of it. Bones also secrete hormones, interact directly with the brain (ever heard of the bone-brain axis?) as well as other organs and fat cells, and even play a key role in immunity. I’ve covered many of the basics of bone health before, and I’d definitely recommend checking those out to augment these suggestions. For today, however, let’s look at some of these lesser known and appreciated functions—as well as some additional tips for supporting bone health throughout the life cycle.
For today’s edition of Dear Mark, I’m answering questions from the comment section of last Thursday’s post on CrossFit, Primal, and carbs. First, I use a comment from Dave to expand on the idea of earning your carbs and eating the carbs you earn. Second, I discuss the notion of athletes using cyclical low-carb diets. Would their performance suffer? And finally, I go over a few more starchy carb sources allowed on the Primal eating plan that I forgot to mention last time.
By far the single most common criticism levied against paleo by CrossFitters is that it’s too damn difficult to eat enough carbs to maintain performance during workouts. There is definitely truth there.
First, let’s establish something. Do CrossFitters indeed need more carbs than your average Primal bear?
Conventional wisdom teaches us to accept our fate when it comes to hair loss. “Runs in the family,” we’re often told—and sometimes it does (but that’s usually not the full story). “It’s just part of getting older,” people say, too—and there we again find only partial truth at best.
But the Primal path is one of thoughtful scrutiny, not blind acceptance. While most people would file hair loss under aesthetic concerns (ranging from neutral to negative depending on social norms and personal views), it’s not always that innocuous. Let’s look today the bigger picture behind hair loss and the situations in which it signifies a genuine health concern.
For today’s edition of Dear Mark, I’m answering three questions. First, is HDL all it’s cracked up to be? Is HDL always good? Is it the savior? Or is the story a bit more complicated? Next, what are some good probiotic options for treating acne? Do any exist? And last but not least, what’s the relationship of artificial sweeteners, insulin, appetite, and weight gain?
Last week I waded into the adaptogen theme, examining the many ins and not-so-many outs of American and Asian ginseng. It got me thinking—why not keep the ball rolling? The ginseng varieties I mentioned are only two among many adaptogens after all.
Let’s dive right in and take up three additional adaptogen choices—along with some additional suggestions for discerning the safest and most potent formulations.
