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
For today’s edition of Dear Mark, I’m answering three questions from readers. First up, what was my main takeaway from the “Japan and meat” video posted last week? Second, are there any circadian-friendly nightlights—ones that don’t negatively affect our natural secretion of melatonin or disrupt our circadian rhythm? And finally, what are my tips for barefoot hiking? How can someone get their feet acquainted with the natural ground, deal with sharp rocks and gravel, and learn to enjoy their barefoot experience in nature?

You can “hack” a lot of your health, diet, and lifestyle. You can cook the entire week’s meals ahead of time, buy high-quality prepackaged foods and ready-to-cook meals, cover your nutritional bases with smart supplementation. You can condense your training time by choosing the right exercises and upping the intensity to a sufficient level. You can fast-track your stamina in a fraction of the time with sprints and intervals.
But you can’t hack sleep. There are no shortcuts to sleep. You can’t escape the need for 7-8 hours (perhaps 4-5 if you’re genetically gifted). The human body needs those hours. The human brain needs those hours to pick up trash and clean up around the cranium. And it needs to arrive at them naturally.
Yet, we try to hack it just the same, with terrible results.Read More
For today’s edition of Dear Mark, I’m answering several questions from readers about my own personal routines and interests as well as a Primal take on beginning fitness. First, what’s my sleep hygiene routine? Do I even have one, and how has it changed over the years? Second, how do I make sure I’m staying on track in life? What’s the “one marker to rule them all”? Third, are there any good supplements or interventions for DOMS—delayed onset muscle soreness—due to training? Fourth, what are two places I’d love to live, and live Primally? Fifth, how should a totally inexperienced person who’s just lost a bunch of weight through eating alone get started with exercise? And sixth, how do I handle myself in eating situations where I have no direct control over the quality of ingredients (oils, etc) used?

On June 23rd, the world changes. Every RV, Subaru Outback, and pickup truck in every neighborhood across the country disappears from city limits. Expect the swoosh of fiberglass poles sliding through tent fabric to resound across the land and millions of campfires to produce enough smoke to block out the sun. Molted marshmallow flows will destroy hundreds of homes, and millions of fathers sitting on Doug fir rounds by the fire will tell so many ghost stories that they summon actual phantoms from the spirit world. The nation’s circadian rhythms will get a hard reset back to the superior factory settings, thanks to avoidance of artificial light after dark. Or so we could hope….Read More
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.

I imagine there are a few souls dragging out there today. For some people, sleep is already the hardest area to change because of shift work, young children, etc. Add to this scenario the lost hour that disappears into the ether every March, and the effects can be miserable. Even for the “best” situations, switching the clock (in either direction) leaves a person feeling oddly displaced, like you’re never where you’re supposed to be at any given time. The world is going about its business in the usual routine, but something feels off—and it takes at least a few days to finally settle back into a circadian congruence.Read More
