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
This is an updated version of a Dear Mark column from 2012. You can find the original version archived here. The below has been completely updated for 2018.
The blank slate hypothesis has fallen. Everyone comes into this world imbued with attributes, characteristics, and predilections that are uniquely theirs. We’re all humans, but we’re a diverse bunch, and that makes it interesting. And though it also makes giving cookie cutter health advice impossible, I just take that as an opportunity to stand out from the crowd and provide actionable advice that genuinely helps real people.
A perfect example is biological sex. Anyone who’s lived with the opposite sex, been married, or had kids of different sexes knows that males and females are different—on average.
There’s a ton of overlap, don’t get me wrong.Read More
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?
Let’s find out:Read More
Generally speaking, the basic Primal Blueprint for fitness and physical activity applies equally to men and women of all ages. Lifting heavy things works in everyone. Sprinting is a fantastic way—for anyone who’s able—to compress workouts and improve training efficiency. Improving one’s aerobic capacity through easy cardio doesn’t discriminate between the sexes. And everyone should walk, hike, garden, and perform as much low level physical activity as possible. These basic foundations—the 30,000 foot view of fitness—don’t really change across age or sex.
But the details do, especially for women.Read More
For today’s edition of Dear Mark, I’m answering five questions from readers. First up, do my recommendations regarding violence and martial arts in last week’s “wildness post” also apply to women? Second, what else can you do with leftover wine? Next, how do I approach my rest and work cycles? Fourth, is phosphatidylserine good for mental stress or just physical stress? And last, does changing how we interpret or react to stress change its effects?

“I became aware of the power of positive thinking after solving my first bout of hypothyroidism. So when a Reverse T3 problem showed up, I actively filled my life with audiobooks, podcast interviews, and films related to spiritual healing, the power of positive thinking, and the power of the subconscious mind.
Make a vision board to hang in your house, or make a smaller version that you can keep private if you don’t want others in the household to see it. Devote the entire vision board to health and healing; it can be a continual source of inspiration and hope while also imprinting your subconscious mind with positive health affirmations every time you see it.
If you are experiencing hypothyroidism for the first time, just know that it is fixable. You have the highest chance of success if you dedicate yourself to learning all that you can about hypothyroidism while adopting a paleo/primal eating and lifestyle strategy to support your goals.

Some months ago the issue of gender bias in medical research came up on the comment board. It was certainly an issue I’d occasionally read about. But I’m also a proponent of lifestyle design and intervention. I don’t spend as much time as others on the nitty-gritty of medical treatment for good reason, but the conversation got me thinking. Maybe it was time for an article after all….
And, so, the questions started coming. How does gender figure into medicine, and what exactly is gender bias in this context? How does it operate? How has it been measured? What consequences are there? How much should it influence our trust in medical literature and subsequent recommendations—the validity of findings, the efficacy of treatment, the safety of drug prescriptions? And, finally, what if any progress are we making or can we count on in the near future?
There are straightforward, pharmaceutical methods for altering specific hormones, and, as I showed in last week’s testosterone replacement therapy post, they can really help. But a safer intervention for your overall endocrine environment is a systemic one. Some might call it scattershot approach in that one input affects multiple endocrine targets. I’d say, “That’s the whole point.”
Today, I’m going to give you some tried and true methods for helping to normalize your endocrine health. These are things that apply to everyone, as far as I can tell. They won’t fix every problem, but they’re good places to start. Whether you’re a post-menopausal woman, a 21-year-old bodybuilder worried about overtraining, or a thyroid patient, these interventions can’t hurt and will probably help.Read More
Last week’s post on testosterone replacement therapy generated a lot of comments and questions, so for today’s edition of Dear Mark I’ll be answering some of them.
From the prostate and heart disease issues to the high T/low free T phenomenon to the question of women and TRT to keto’s effect on testosterone to chronic cardio’s, you folks came up with some good ones.Read More
Keto is fantastic, everyone says. It’s a great way to lose weight, improve cognition, and stave off degenerative disease. It may help your performance in the gym and on the track. It could even give Grandpa some respite from Alzheimer’s.
But it’s hell on your thyroid. Right?
Keto detractors and proponents alike often warn that remaining in ketosis will tank your thyroid. The thyroid’s an important gland, exerting major influence over essential systems like fertility, energy, metabolism, body temperature regulation, blood lipids, and general wellness. It controls the metabolic rate of every organ in the body. We want it working well, so this is a major blow to keto—if the criticism holds true. Fortunately, there’s much more to this story.Read More
Today’s post is served by good friend to Mark’s Daily Apple, Stephanie Greunke. Stephanie has teamed up with Melissa Hartwig of Whole30® to create the Healthy Mama, Happy Baby program.
Food aversions and nausea plague up to 80% of women during the first trimester of pregnancy, which can be really frustrating for the mama who is trying to eat a healthy, nourishing diet. While there is no one specific cause of food aversions and nausea, some of the proposed factors include increased hormone levels (specifically estrogen, progesterone, and hCG), hypoglycemia, thyroid dysfunction (specifically increased serum free T4 and decreased serum TSH), a woman’s enhance sense of smell, stress, Helicobacter pylori (H. pylori) infection, and physiological changes of pregnancy such as delayed gastric emptying and constipation.Read More
