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...

How Much Meat Is Too Much?

I’ve discussed—and countered—many misconceptions people hold to be true about the Primal lifestyle. That we wear loin cloths and shun modern medicine (I only do one of those), eat so low-carb all the time that running our urine through a coffee filter produces valuable ketone esters (stay tuned for the supplement!), and avoid cardio to the point of scolding ourselves if we have to run to catch the train (only if we jog rather than sprint). One in particular has stuck: that we’re meat-obsessed.

This one isn’t totally unfounded. We do enjoy our bacon, our steaks, our lettuce-wrapped burgers, our legs of lamb, our roast chickens. Personally, I emphasize the animal foods (which include “meat”) for two reasons: they’re extremely nutrient-dense and they’ve gotten a terrible rap for decades. We should be eating them on a regular basis but, by and large, people are scared to. There’s always that voice in your head repeating back to you the scary “red meat will give you cancer” or “meat consumption linked to diabetes” headlines that pop up every few weeks. I consider it my job to remove the stigma of healthful animal foods, to highlight the importance and vitality of meat in the human diet.

Dear Mark: Dried Sardines, Pullup Alternatives, and Blood Donation for Women

For today’s edition of Dear Mark, I’m answering three questions from readers. First concerns an alternative form of a food I’ve always urged people to consume: small dried whole fish. Are the omega-3s still viable after the drying process? Next, pullups are a fantastic exercise that everyone with the ability should perform, but not everyone has access to a pullup bar. What other exercises can you do to approximate, if not altogether replace, the humble pullup? And finally, in previous posts I’ve mentioned the potential health benefits of regular blood donation for men. Does the same apply to women? After all, they already “donate” blood on a regular basis through menstruation. What about post-menopausal women?

8 Primal Rules for Building Better Bones

Strip away the skin, fascia, muscles, organs, blood vessels of a human and you’re left with the bones: the foundation providing passive structural support. Many people accept that we can affect and even control the health of the rest of our tissues. Muscles? Just lift. Cardiovascular system? Do some cardio and lose weight. Teeth? Stop sugar. But bones just wear down the older you get. Everyone knows it. And sometimes bones just break. There’s nothing you can to prevent it and nothing you can do to improve your healing except wait and hope. If you want stronger bones, you’ll need some pharmacological assistance provided by a white coat-clad adult wielding a prescription pad.

But bones aren’t inert. They are living metabolic tissue. And though we can’t tell them what to do directly, they grow—or diminish—in response to the signals we send. What kind of signals should we be sending?

Dear Mark: Do High Protein Diets Cause Colon Cancer?

For today’s edition of Dear Mark, I’m talking about a new rodent study has just been released that seems to identify the general low-carbish, Primal-ish way of eating as bad for GI tract health. I know, I know. It seems odd, especially since so many people get relief from digestive disorders, inflammatory bowels, and irritable guts after ditching grains and eating more animals and plants. I’ve certainly benefited from going Primal, having spent decades of my life being ruled by IBS to enjoying pristine bowel health the last decade and counting. But what do I and millions of others know?

Let’s dig into it.

Top 14 Ways to Increase Your Metabolism

On a literal level, your metabolic rate describes how much energy you expend to conduct daily physiological functions. This has many practical ramifications, however, because your metabolic rate also influences how you feel, how many calories you burn, how many calories you can eat without gaining weight, your libido, your fertility, your cold tolerance, how much subjective energy you have, how you recover from injuries and stress, how specific foods affect you, and how you perform in the gym. In short, it’s usually a good thing to have a higher metabolic rate.

Here are a few ways to increase your metabolism in a healthy, productive manner.

Dear Mark: Grass-Fed vs Grain-Finished, Lamb Feedlots, and What About Grass-Fed Eggs?

For today’s edition of Dear Mark, I’m answering a few questions about grass-feeding several of you raised in last week’s comment section. First, is there a difference between grass-fed and grass-finished?What is the difference between grass-fed and grass-finished? Next, is it true that lamb is by definition grass-fed? Are there actually lamb feedlots, or can we be certain that the lamb we eat lived a fairly decent, grassy life? And finally, what about grass-fed eggs? Does such a thing even exist? After all, when most of us think about happy egg producers, i.e. fowl, are they munching away on their fair share of freshly sprouted greens?
