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 to Buy (and Appreciate) Eggs

Time and again I find myself on the topic of eggs. I’m a fan really. In fact, I had them for breakfast just this morning (as most mornings).

They’re one of nature’s true superfoods after all—pre-packaged and ready to enjoy however you see fit. The healthy fats, proteins, vitamins and minerals contained within simply can’t be ignored, regardless of all those misguided cholesterol-haters out there.

Back in 2008, I provided a brief look into deconstructing egg carton labelling. That simple guide to egg purchasing has gotten a fair amount of attention and shares over the years, so I’m revisiting the subject to update and elaborate where it makes sense. I don’t see eggs ever losing their place in paleo/Primal eating, and I know others share my enthusiasm.

Dear Mark: Your Challenge Questions Answered

Last week, you guys asked me a ton of questions as part of a contest. Today, I’m going to answer an initial batch. (If you don’t see yours, check back on Mondays to come when I’ll take up others.) First, can excess fat be stored as body fat? If so, how? Second, can this way of eating help with seasonal allergies? Third, what’s the proper pushup progression for someone who can’t do a full one? Fourth, when should I take my probiotics, vitamin D3, and fish oil? Fifth, is canned fish a viable way of obtaining omega-3s, or does the canning process damage the fats? Sixth, is there a trick to beating a weight loss plateau? Seventh, is there a way to make sardines palatable? And eighth, if you can’t walk one day, can you make it up the next?

Let’s go:

The Benefits of Caloric Efficiency (and 10 Ways to Achieve It)

We really like to eat. We choose restaurants based on portion size. We work out just to increase our capacity for guilt-free gluttony. And even when we don’t actually like it, we still want it because the food industry employs experts in brain hedonic processing to engineer food products your brain literally cannot stop craving. As Louis CK put it, we don’t stop eating when we’re full, we stop eating when we hate ourselves.

I’m not immune. In college, they called me Arnold, after the pig from Green Acres, because I could (and did) out-eat anyone. Linebackers 1.5x my size were no match. I love food, but I’m not interested in cramming as much food as I can get away with. Not anymore.

Updating the Primal Stance on Vegetable Oils: High-Oleic Varieties

Many years ago (I initially wrote that in jest, but it has been almost seven years), I wrote a definitive guide to oils, covering the benefits and drawbacks of over a dozen of the most common edible oils. Seven years is plenty of time for new data to come out, new perspectives to develop, and even new oils to hit the market. How would I go back and update my previous recommendations?

Most of it stands. The fatty acid breakdown and overall assessment of each oil remain valid and sound. Olive oil is still olive oil (unless it’s not). 2016 peanut oil is identical to 2010 peanut oil. If you’re interested in the basics or want to see my 2010 take on edible oils, go ahead and read through the Definitive Guide to Oils.

Dear Mark: High-Fat Diet, Gall Stones, and NAFLD

For today’s edition of Dear Mark, I’m answering two questions. Both concern the gallbladder. First, how does a high-fat ketogenic diet relate to the presence of gall stones? Can the former cause the latter? Or is the story a bit more complicated than that? Then, I discuss which fats are most amenable to the gall bladder-less. Also, where does non-alcoholic fatty liver disease, or NAFLD, come in?

How Should You Balance Your Fat Intake?

We’ve put to bed the misguided notion that saturated fat is out to kill you, clog your arteries, make you fat, and disfigure your unborn children. We’ve scrutinized the widely-held assumption that processed seed oils rich in omega-6 linoleic acid are the healthiest fats available, made a strong case for a fat-based metabolism, and sung the praises of monounsaturated fat. Fat is back. Fat’s been back for a long time now. But is that all there is to it? Should we eat all the saturated fat we can get? Should we avoid linoleic acid at all costs? Where does MUFA come in? Fish oil?
