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
If you’ve been paying attention, you’ll know that I’m not a big fan of protracted stretching routines or extended warmups that end up taking longer than the workout itself. I like simplicity. I like cutting corners without sacrificing quality or results. I’m okay with warmups that fulfill their basic goal – getting the muscles warmed up and ready for movement – and with active stretches that move you through the full ranges of motion you’ll be traversing during the workout, but that’s about it. If there was strong evidence in favor of stretching as a protective measure, I would be all over it, because I hate down time. But the latest research indicates that stretching is harmless at best and a performance-detractor if done excessively. Furthermore, warmups, while effective in the right doses, can lead to fatigue and lower performance if overdone.
So what does the research say and what should we be doing (if anything) to prepare for physical activity?
There’s nothing like living Primal in summer. Certain aspects just come easier: the copious fresh produce, unlimited outdoor exercise, long daylight, ample sunshine. True, those of us in the warmer states have some year-long advantage here. Nonetheless, summer remains my favorite season – probably a result of my New England roots. The brevity of the season there inevitably inspires a true carpe diem attitude. Wherever you go, however, I think summer brings with it a sense of adventure and spontaneity. Even if our school years are (decades) long gone, we still embrace summer as a kind of “holiday” from the routine. For many of us, the season is a time to explore, travel, and live outside, relegating the house to role of mere storage unit. There are the elaborate vacations, the well-planned day trips, the sporting and social events. Today, however, I’m thinking along nostalgic lines, some old school pastimes that invoke the (somewhat endangered) ease of summer.
Having immersed myself in all things Primal for so long, I find myself viewing nearly everything through the prism of human evolution. Is this food, activity, environmental stimulus, or social more an evolutionary novelty? If so, might it possibly conflict with or impede our pursuit of good health? Is it benign? An improvement, even?
Grok logic will only get you so far. It’ll give you a nudge in the right direction – that is, headed straight to honest inquiry and further research – but it’s not enough. You shouldn’t rest on your laurels if Grok logic suggests what you’re doing is right, and you shouldn’t make big changes just because Grok logic suggests you’re doing something wrong. Instead, use those insights to generate hypotheses, then try to explore them. Research, read, ask more questions. At least, that’s what I try to do. It’s awfully tempting to just go with conjecture (especially if it turns out to be right on a fairly regular basis!).
Today’s Dear Mark roundup is a trio of oil-related questions. Learn about my adventures with MCT oil and whether it fits into a good eating plan. Hear about camelina, the “better flax.” And finally, we’ll go over whether fancy, cold-pressed canola oil is worth including or whether it’s still just canola oil.
I’m thinking I’ll stick with this format for awhile. The response has been mostly positive, so why mess with what works? If ever a question arrives that merits a devoted full-length post, I’ll do that, but for now this seems like a hit.

Living in the city changes how your brain responds to stress, and not in a good way.
Fake, manmade fat strikes out again. This time, rats who ate potato chips made with Olean, the non-caloric “fat,” got fatter and ate more than rats who ate regular chips. Big surprise.
More fossil evidence that agriculture took a toll on human height (and health).
It seems humans may possess a dormant ability to sense the Earth’s magnetic fields, a la birds and sea turtles, thanks to a tiny protein in our retina. Magneato.
