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: Bacon Fat Stability, Noise Machines, and Pig Feed

Is there any food more lauded and feared, beloved and bewitching, hated and praised – all at the same time – than bacon? Have full-fledged Internet subcultures sprung up around any other animal product? Does any food but bacon inspire obvious longing masquerading as righteous rancor and vitriol? And yet no matter how much has been written about bacon, questions inevitably and indefinitely remain. Case in point: today’s round of questions. That’s right, we have two bacon-related questions and one unrelated question about noise therapy and sleep. I’ve got to say – this really warms my heart. Not only are you trying to find pastured bacon and wondering about what the pork you eat is being fed, you’re also trying to figure out how to sleep better. How much more Primal can you get?

9 Ways You Might Be Inadvertently Sabotaging Your Weight Loss Efforts

Whenever friends, co-workers, or loved ones complain about not being able to lose weight and turn to us for answers or advice, we can all generally rattle off a few suggestions that, if followed, usually set them on the right track. For the soda-swilling cubicle mate who keeps a recycling bin just for cans beneath his desk who asks, “Why can’t I lose weight?,” you suggest stopping soda. For the fast food addict who wonders why she can’t hit her high school weight, you suggest avoiding fries, getting water, and ditching the buns. To the vegetarian best friend who eats “healthy” but is growing increasingly skinny-fat, you send a link to MDA. Those are simple solutions. What about your stalled weight loss? You’re Primal, you’ve lost a bunch of weight already, you’re feeling good, you don’t have many complaints, you know all about nutrition, and you’re sticking with the lifestyle – but you’re not losing as much weight as you’d like. Well, it could very well be that you’ve inadvertently throw a wrench into weight loss efforts.

What do I mean? Let’s take a look:

Action Item #5: Slow Life Down

Of all the Action Items, #5 can be the hardest or the easiest for people. (Confession time: it’s the one I still work on.) It’s probably the most far-reaching of the AIs, but likely the most fun. In the midst of great Primal fare and Grok approved exercise, there’s the rest of life after all. This Challenge emphasizes genuine transformation, and that means optimizing all the major fronts of life and lifestyle. Overhauling your diet and movement will absolutely reshape your health, but true thriving encompasses a broader, more nuanced sense of well-being. It’s about fulfillment, contentment, and vitality – both physical and mental. Just as the other Action Items guide you to examine and often revamp your daily choices for better health, #5 brings the same scrutiny and strategizing to other aspects of life. The purpose is familiar by now: to let go of practices that don’t serve your well-being and implement those that do.

How to Conduct a Personal Experiment: Yellow Light Exposure (plus an Announcement)

You guys ready for another personal experiment? I hope so. Even if don’t think you’re ready to take something on, I’m confident you’ll be able to handle this one, because it’s relatively simple, intuitive, and easy. It’s also something I’ve been discussing for a couple years now, so you’re most likely familiar and comfortable with the concept. But most importantly, today’s experiment is a gentle one that requires very little commitment. No jumping in freezing cold water, no drastic changes to your sleeping schedule. All I’m asking you to do is experiment with nighttime yellow light exposure.

Huh?

Remember how I wrote about nighttime exposure to blue light affecting melatonin secretion and, subsequently, sleep quality and duration way back when? Yeah, that. In case you didn’t read it, I’ll give a quick explanation:

How to Conduct a Personal Experiment: Biphasic Sleeping

It’s time for another edition of “How to Conduct a Personal Experiment.” Last week, it was the cold water plunge. Today, we’re going to talk about running a biphasic sleep experiment. First, though, I’d like to know: how are the cold plunges going? Are they, well, cold? More importantly, did you have any difficulties setting up the experiment, identifying variables, and choosing what to measure and track? This whole personal experiment stuff is likely new to most of you, and while there’s no real “wrong” way to go about it, there will be some initial difficulties. Be sure to keep us posted in the comment section.

Okay, on to the new experiment.
