Meet Mark

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...

Dear Mark: Potato Diet, Lean Gains, EVOO/Butter/Ghee, Exogenous Ketones, and Early IFing

For today’s edition of Dear Mark, I’m answering several questions drawn from the comment board of last week’s post on fasting vs carb restriction. First, how do I square my recommendations with the successful reports of potato dieters losing weight on a high-carb tuber diet? Second, is Leangains optimal for mass gain? Third, how do I use extra virgin olive oil, butter, and ghee? Fourth, could exogenous ketones help a man with dementia, MS, and seizures? Fifth, how should a woman with stalled weight loss integrate fasting?

Let’s go:

Fasting versus Carb Restriction: Which Works Better for What Scenarios

Both fasting and carb-restriction appear to operate along similar physiological pathways. Both lower carbs. Both increase fat-adaptation. Both have the potential to get you into ketosis. Both lower insulin and blood sugar.

But is one better than the other? Are there certain scenarios in which an intermittent fasting protocol works better than a low-carb diet, and vice versa?

Let’s find out if the distinction matters.

And what scenarios are most impacted by any difference.

5 Ways a Primal Health Coach Can Help You Overcome Sugar Addiction

Today’s post is offered up by Dr. Dana Leigh Lyons, certified Primal Health Coach and author of Sugar Addiction: 5 Healing Steps. 

Why, despite knowing the consequences, do we keep reaching for that extra piece (or two or three) of chocolate?

Well, let’s face it. For many of us, sugar addiction began when we were kids. Breaking a sugar habit is so hard! But it’s totally possible.

Sure, you could do it on your own…but as a Chinese Medicine doctor and health coach, I’ve found that personalized support and accountability are what make the most difference for most people.

That’s where a Primal Health Coach comes in! They can help you overcome sugar addiction and get you where you want to be with health and eating. Here’s how.

Is Constant Ketosis Necessary – Or Even Desirable?

Good morning, folks. With next week’s The Keto Reset Diet release, I’ve got keto on the mind today—unsurprisingly. I’ve had a lot of questions lately on duration. As I’ve mentioned before, a good six weeks of ketosis puts in place all the metabolic machinery for lasting adaptation (those extra mitochondria don’t evaporate if/when you return to traditional Primal eating).

But what about the other end of the issue? How long is too long?  I don’t do this often, but today I’m reposting an article from a couple of years ago on this very topic. I’ve added a few thoughts based on my recent experience. See what you think, and be sure to share any lingering questions on the question of keto timing and process. I’ll be happy to answer them in upcoming posts and Dear Mark columns.

Cool Things You Notice Happening Once You Start to Lose Weight

Most people come to the Primal Blueprint because they want to lose weight. Ask any purveyor of a specific diet and they’ll say much the same thing. The majority of people are interested in dropping body fat, looking good naked, and fitting into their clothes. The interest in overall health, fitness, and lifestyle tends to develop organically out of that. Come for the weight loss, stay for the blue-blocking goggles.

There’s a tendency to view weight loss as superficial compared to the other stuff. That’s a mistake. Weight loss isn’t just about belt notches and positive experiences with mirrors. It confers measurable and, most importantly, tangible benefits to health, happiness, and daily functionality almost immediately. Fat loss, it turns out, isn’t a flighty pursuit. It solves a lot of serious problems and makes some really cool things happen.

What Is the Vagus Nerve? (and How Does It Impact Health, Mood and Performance?)

In recent years, I’ve regularly vouched for the gut as our long-abused secondary brain. Given what most of us grew up learning in school, it can feel like a mammoth shift. Science and philosophy have long revered the brain as seat of consciousness, even the seat of humanity itself. But when it comes down to it, everything is interconnected. Our consciousness extends well beyond the brain. How we feel and who we are encompasses a much more expansive and intricate system than any of us learned in high school biology. At the center of this paradigm revision is something called the vagus nerve.

Vagus…as a word it sounds a little off-putting. If someone called me a vagus, I’d probably be mildly offended. But the literary origins of this word are actually kind of mystical: “vagus” in Latin translates to “wandering.” And I’d struggle to find a more apt definition.
