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: Phones in Bedrooms, Antidepressants, Pastured Egg Omega-6 Content

For today’s edition of Dear Mark, I’m answering three questions from readers. I’ve come down hard against phones in bedrooms in the past. Is there a “good way” to use your phone in the bedroom? Reader Kathy offered some good reasons for keeping a phone there; what do I think? Next, HealthyHombre laments having to take antidepressants (but he shouldn’t lament). And finally, I cover the differences in omega-6 between pastured eggs and conventional eggs.

Dear Mark: PUFA Confusion, Mushroom Coffee, Swiss Water Process, and Timing the Fast

For today’s edition of Dear Mark, I’m answering four questions from readers. First, should someone homozygous for the FADS variant that increases PUFA conversion eat less or more PUFA? Next, what’s the deal with all the mushroom coffees out on the market? Are they actually beneficial? Third, when looking for a healthy decaf coffee, what should you watch for? And finally, how should a breakfast skipper/intermittent faster deal with increased morning hunger caused by morning workouts?

Dear Mark: Power Yoga, Pelvic Floor, Keto Reset and Osteoporosis

For today’s edition of Dear Mark, I’m answering three questions. First, is power yoga—a more “intense” version of yoga that includes strength exercises—a suitable alternative to strength training for aging women? Probably not, but that doesn’t make it bad or wrong to do. Second, what’s the deal with pelvic floor dysfunction after menopause? What’s the best way to improve that situation? And third, is the Keto Reset right for older women with osteoporosis?

Dear Mark: Coffee and Cancer, Beef Cheeks, Paleo Pancakes

For today’s edition of Dear Mark, I’m answering a few questions from readers. First, what do I make of the news that coffee sellers in California are going to start putting “may cause cancer” warnings on their labels? Is there anything to the cancer and coffee claims? Next, why didn’t we include beef cheeks in the “cheap cuts” post last week, despite being big fans of the cheek? After that, I explain why I included a recipe for fried scallion pancakes in last week’s Weekend Link Love.

Dear Mark: Folate Retention in Beans, Seeds, and Greens, Blended Liver Folate, No Vegetable/Fruit Full Study

For today’s edition of Dear Mark, I’m answering three questions. You guys had more questions about folate. Since it’s such an important vitamin, I answer those first. Then I discuss the study mentioned in last week’s Dear Mark in which removing polyphenol-rich fruits and vegetables from the diet improved oxidative stress markers instead of worsening them. I got my hands on the full study, so I have more to say on the subject.

Dear Mark: Vitamin B and Lung Cancer, Folate Stability in Liver, and Less DNA Damage on No Produce

For today’s edition of Dear Mark, I’m answering three questions from readers. First, what do I make of the recent study showing a link between lung cancer in men and supplementation with vitamin B6 and vitamin B12? Next, how stable is folate in liver? Other foods with high folate content before cooking, like legumes and greens, lose a lot during cooking. And finally, what’s my take on the old study where subjects’ markers of oxidative damage improved after eating a diet bereft of produce?

Dear Mark: Folate Follow-up

For today’s edition of Dear Mark, I’m answering five questions taken from last week’s folate post comment board. Does folic acid increase cancer risk? It’s an open question, but I think we have a pretty good idea of where the research points. Next, what other nutrients can help people with MTHFR mutations? Is there anything else someone with a deleterious variant should focus on eating? Third, is folate good enough, or should you look specifically for 5-methyltetrahydrofolate? Fourth, how do I know if I have a MTHFR variant that increases the need for folate? And finally, what specific form of folate am I using in Master Formula?

Dear Mark: Peanut Edition

For today’s edition of Dear Mark, I’m answering a bunch of questions from last week’s post about peanuts. You guys had quite the reaction to it, and today I’m digging into some of your questions and comments. Does roasting create carcinogens in the fat? Should (and can) you sprout peanuts? Are peanuts used to soak up toxins from the soil? How do I know if my peanut butter comes from Valencia peanuts?

And many more.

Dear Mark: Improving Exercise Stress Tolerance, Stress and Athletic Performance, My Stress Practices, Non-Negotiable Stress, and Distractions

For today’s edition of Dear Mark, I’m answering five questions about stress. First, how can someone handle the stress from training five days a week, assuming they don’t want to cut back on gym days? Second, what are the negative effects of chronic stress on athletic performance? Third, what do I do when I’m stressed out and Primal Calm isn’t cutting it? Do I have any practices? And fourth, how can a working mom with three little kids deal with non-negotiable stress? Fifth, can distractions like TV or movies help us deal with stress, or are they just ways to ignore the problem?

Dear Mark: More Embracing Your Wildness

Last week’s Q&A about cultivating wildness was a lot of fun, but there were some questions I didn’t get to in the original post. Today, I’m going to answer some more. From stirring stories of a father and son pursuing and living their dream after experiencing extreme tragedy to how to go barefoot more safely to the balance between creativity, progress, and Primal values to accepting the reality (and beauty) of having work to do to the value of sun exposure in winter to circadian entrainment. In short, we’re covering a ton of ground today.
