The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate in...
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
Last week’s post on iron levels got a big response and garnered a ton of questions from you guys. Today, I’m going to clarify a few things and answer as many questions as I can. First, do iron and ferritin levels mean different things for men and women? If so, how do those differences manifest? What about premenopausal women vs postmenopausal women? Second, what do we make of the fact that ferritin is also increased in times of inflammation? Is there a way to distinguish between elevated ferritin caused by inflammation and elevated ferritin caused by high iron? Third, is desiccated liver a good option for liver haters? And finally, I share some exciting plague news.Read More
So you start your keto diet, and things are going well. You’re dropping excess fat, your carb cravings are noticeably reduced, your energy is steady throughout the day… and then one day you start to have the sneaking suspicion that you’re shedding more hair than usual. After a few days, it’s unmistakable: your hair is definitely falling out at an alarming rate.Read More
Men occupy an interesting place in the health sphere. While there’s a disparity—albeit one that’s approaching parity—between men and women in the conventional medical literature, in the alternative health world, it’s flipped. Women are a “special interest” group, and their specific health issues and special considerations related to diet and exercise receive a lot of attention, often as a way to counteract the conventional imbalance—and because women tend to be higher consumers of health information. I have far more posts (including a post on Keto For Women) explicitly directed toward women and women’s issues (and the same can be said across many ancestral health sites).
Men are assumed to be “the default,” requiring no special consideration, but is that actually true?Read More
Most people chalk urinary incontinence and excessive urgency up to age. We get old, stuff stops working, we wake up to wet sheets. Cue jokes about adult diapers and investing in “Depends” futures. It’s not entirely out of line. Aging matters. There’s just more to it. Like other aspects of “aging,” incontinence and unreasonable urgency don’t just “happen.” Aging may hasten or accompany the decline, but it’s by no means inevitable, unavoidable, or unmitigated.
There are surgical treatments available, many of which involve the implantation of balloons and slings and rings and hammocks. Those are beyond the scope of this post, which will focus on exercises and other less invasive interventions and preventive measures.Read More
For today’s edition of Dear Mark, I’m answering two questions from readers. First, is it possible to become deficient in omega-6 fats as an adult? What would that even look like, and is there anything that might make omega-6 more important?
Second is a question related to last week’s feature on prostate health. Is saw palmetto an effective supplement for prostate issues? It depends on the issue.

Many of you have asked about prostate health in a Primal context. Men are interested because they know men have a decent chance of getting prostate cancer. Women are interested because they’re worried about the men in their lives getting prostate cancer. Today, I’m going to delve deep into the topic, exploring the utility (or lack thereof) of standard testing, the common types of treatment and their potential efficacy, as well as preventive and unconventional ways of reducing your risk and mitigating the danger of prostate cancer.
Let’s go.Read More
It has many names and monikers.
Age-related testosterone deficiency.
Manopause, my personal favorite.
Although it isn’t as sharply defined as female menopause, male menopause is a catch-all for the gradual cascade of mental and physical health issues that men face as they approach and pass middle age and their testosterone drops. Wherever possible, I will insert “man” puns into the symptoms and conditions. Consider yourself warned.Read More
For today’s edition of Dear Mark, I’m answering three questions from readers. There was some good feedback after last week’s sauna post, and I want to address a few of the comments. First, does the fact that Finns don’t live as long as some of the other more storied “blue zone” populations despite using saunas negate the utility of the sauna? Second, what should we make of the recent study showing negative effects of sauna on sperm health? And third, isn’t it more “natural” and Primal to seek out smaller ambient temperature fluctuations, rather than brief exposures to extreme temperatures?

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
