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...

How We’re Setting Our Kids Up to Be Fat, Sick, and Unhappy

I’ve been on a bit of a “children’s health and wellness” kick lately, with a couple posts discussing the importance — and, unfortunately, dearth — of free play and exploration in our children’s lives. Some of you have speculated via email that Carrie and I have something to announce, but that’s definitely not the case. This is simply an important topic for everyone with a stake in the future of this world. The mental, physical, and spiritual health of our children today will determine our trajectory through history in the decades to come. If a fat, sick, and unhappy generation takes the reins of this planet, nothing good will come of it.

Dear Mark: Moonlight and Melatonin, Exercise Non-Responders, and Is Weight Loss Impossible and Unhealthy?

For today’s edition of Dear Mark, we’ve got three questions and three answers. First, the full moon sure is pretty and big and bright at night, but can it produce (or reflect, rather) enough light to disrupt our melatonin production? Should we be blocking out moonlight, too? Next, do exercise non-responders exist? If not, what else can explain the curious case of a lifelong heavy lifter who has nothing – physique-wise – to show for it? And finally, a recent article in Slate makes the claim that weight loss is basically impossible and not even all that good for you. Is the author right? Is the author wrong? See my thoughts on the matter down below.

25 Ways to Improve Your Insulin Sensitivity

Insulin does a lot of important things for us. It pulls glucose from the blood and fritters it away into our cells to be burned for energy or stored as glycogen. It prevents hyperglycemic toxicity to neurons, pancreatic cells, the arterial walls and the generation of excessive levels of reactive oxygen species. It even promotes muscle protein synthesis and helps augment muscular hypertrophy, especially following resistance training. Clearly, we need insulin. Without it, we’d die, as type 1 diabetics readily do without an exogenous source.

Dear Mark: Kid Skipping Breakfast, Rinsing Meat, Glutamate, and the Snooze Button

For today’s edition of Dear Mark, I’m answering four reader questions. First we have a question about an inadvertently fasting 11 year-old girl whose mom is concerned. Should she force the issue and convince her to eat breakfast, or let her do her thing? Second, what’s the real story behind rinsing raw meat? Does it actually remove bacteria and reduce the chances of food-borne illness? Third, is glutamic acid, or glutamate, really a health concern for everyone? MSG is one thing, but what about glutamate found in real, otherwise healthy foods like meat, sardines, and aged cheeses? And finally, I discuss whether or not hitting the snooze button is good for you.

Why You Should Have a Morning Routine

Let’s consider a tale of two mornings.

The alarm blares. You have exactly seventy-five minutes to be out the door. After relinquishing fifteen of those to one “snooze” period and a few minutes on your phone (e.g. checking email, Facebook), you’re up. You put together coffee, feed the dog and let her outside, get the kids up, and help everyone grab something to eat. Within ten minutes, the clamor and chaos of the morning rush has taken over your thinking – in addition to the nagging reminder that you still have a few emails to send out before the first meeting at 9:00. So much for easing into the day… Even with the tag team approach made possible by a partner, it’s still a major production to hit the shower and get ready. There are bags to be packed, bills or homework to be gathered and final goodbyes to be said as everyone heads out the door. When you get to work, it’s a dash to fit in several tasks before 9:00. Somehow you keep waiting for a quiet moment to pull your thoughts together, to breathe and catch up with yourself, but the chance keeps further distancing itself like a teasing mirage in the desert. Later, you say. At lunch? After work? At night? Wait a second… I forgot my lunch again, didn’t I?

Now let’s look at a better way.
