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
For many women, menopause can introduce new health challenges. In addition to the symptoms that perturb basic quality of life like hot flashes, headaches, night sweats, and irritability, menopause is also associated with higher risk for serious health concerns like osteoporosis, cognitive decline, and metabolic syndrome. This has made the standard treatment for menopause—hormone replacement therapy, or HRT—a multi-billion dollar business.
A few weeks ago, I explored the benefits and risks of HRT. It has its merits certainly, but it’s not for everyone. Today’s post is for those people. Say you’ve waded through the morass of HRT research and would prefer a different route. Or maybe you’ve actually tried conventional or bioidentical HRT and found it just didn’t work for you. Whatever the reason, you’re probably interested in using “natural” products if you can swing it and if it’ll actually help.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
In today’s edition of Dear Mark, I’m talking about pregnenolone, the “master hormone.” Most of the hormones we talk about, like testosterone, estrogen, and cortisol, all have pregnenolone as their precursor hormone. What can happen when pregnenolone goes too low? Can taking pregnenolone solve any problems? Is menopause actually a pregnenolone deficiency?
Let’s find out….Read More
A Primal woman’s first reaction to the prospect of taking synthetic hormone replacements for menopause? Probably a healthy dose of skepticism. We in the ancestral health community, after all, tend to view pharmaceuticals as a last resort—interventions that are overprescribed by vested interests, create their own set of side effects, and may even do more harm than good. To suggest that we “need” this or that prescription raises our hackles.
Besides, it’s not like menopause is a product of modernity or an aberration our ancestors never experienced; it’s a physiological stage that evolution has protected and selected in humans. It’s perfectly natural. Rather than the debilitating, miserable experience many women report having, menopause should be easier. Graceful, even. But it often isn’t.Read More
After my recent post on keto for women, I got a lot of feedback. One of the most common themes: “But what about menopause?” I heard from dozens of women in both the comment section and in emails who were having trouble losing weight and dealing with the varied symptoms of menopause. Was keto the answer? Was Primal? Were they doing something wrong?
Rather than start with the assumption that going keto or Primal is the best way to deal with menopause, I figured I’d start from ground zero, drawing on the extensive scientific literature on diet and menopausal symptoms to see if I could arrive at some general trends and make recommendations.Read More
For today’s edition of Dear Mark, I’m answering three questions. First, what are some less expensive sources of marine fat high in omega-3s? Is canned salmon a good, safe, effective option? Second, a reader is training hard, eating low-carb/keto, doing IF, and feels pretty good despite not losing or gaining any weight? What should she do? What could she be doing wrong? And third, should you go keto while nursing?

Keto is exploding. No longer solely the province of cutting edge bodybuilders or longevity enthusiasts and neurodegenerative disease warriors, keto has invaded every walk of life. I hear about it in grocery stores, coffee shops, spin classes, business meetings, dinner parties, morning talk shows. Judging from our blog and sales metrics, women make up the largest group of recent entries into the diet. This is great, but it also comes with a small wrinkle: Just like they should do with fasting, most women need to take special precautions when implementing a ketogenic diet.
To begin with, one of keto’s main benefits is also its biggest stumbling block for women: The inadvertent reduction in calorie intake and massive increase in satiety.Read More
Last week, I updated an older post on women and intermittent fasting. For today’s edition of Dear Mark, I’ll be answering some of the comments and questions from that post. First, should a lean woman with a stressful life try fasting to heal her gut? Maybe, maybe not. Second, does coffee break a fast? Now, where have I heard that one…? Is a 12-hour fast a good starting point for women? What are the IF “pre-reqs”? And finally, what do we make of women who can fast successfully? Does habituation have an effect?
