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...

Is Gluten Sensitivity All in Your Head?

First, non-celiac wheat/gluten sensitivity was a sham and everyone claimed its participants were in a collective mass delusion. Then some actual studies came out, and it appeared to be a real condition. Soon after, researchers offered different theories. Maybe it was FODMAP intolerance. Maybe it was all that wheat fiber messing up the gut. Maybe it was too little fiber and other fermentable substrate, and we were actually starving our gut bugs and compromising our intestinal health. Maybe it wasn’t even the gluten. And maybe it was actually some kind of a placebo. One of the most recent findings was that gluten sensitivity might not even exist. What’s the truth?

10 Ways to Beat the Low-Carb Flu

The low-carb flu is real and it’s terrible. While it doesn’t kill as many as the Spanish flu of 1918 did or inspire the amount of panic seen during the 2009 swine flu epidemic, low-carb flu has dissuaded millions of people from pursuing and sticking to a healthy diet. You can laugh now that you’re fat-adapted and humming along on stored body fat, but you’ve forgotten just how terrible the transition from sugar-burning to fat-burning can be. Do any of the following symptoms sound familiar?

The Fat Burning Brain: What Are the Cognitive Effects of Ketosis?

Although mainstream sources still mistake “the brain needs glucose” for “the brain can only run on glucose,” regular MDA readers know the truth: given sufficient adaptation, the brain can derive up to 75% of its fuel from ketone bodies, which the liver constructs using fatty acids. If we could only use glucose, we wouldn’t make it longer than a few days without food. If our brains couldn’t utilize fat-derived ketones, we’d drop dead as soon as our liver had exhausted its capacity to churn out glucose. We’d waste away, our lean tissue dissolving into amino acids for hepatic conversion into glucose to feed our rapacious brains. You’d end up a skeletal wraith with little else but your brain and a hypertrophied liver remaining until, eventually, the latter cannibalized itself in a last ditch search for glucose precursors for the tyrant upstairs. It would get ugly.

12 Common Causes of Bloating (and How to Eliminate Them)

We’ve all been through it. You come home after a big day at the dog park, your owner pours a few cups of meaty kibble, and in your zest you can’t help but inhale the food. You chase it with a bowl-full of ice water. Sated, you try to lie down under the dining room table, but you can’t get comfortable. No position feels right. There’s something pressing on your insides. You feel like vomiting, but nothing comes out. Several dry retches later and the reality of the situation hits you: bloat. On goes the leash and you’re off to the emergency vet for a quick intervention.

Oh, wait. That’s not right. Sorry, I warged into my goldendoodle for a second. Bloat kills dogs. In humans, bloating isn’t fatal. But it is unpleasant, unattractive, and uncomfortable. It’s also difficult to pin down because it’s so nebulous. Let’s try anyway.

Dear Mark: How to Eat Blackstrap Molasses; Healthy Whole Grains Studies

For today’s edition of Dear Mark, I’m answering two reader questions. First, I answer a very specific question about blackstrap molasses, that nutrient-dense sweetener with the distinctive taste. How can a person who hates molasses work it into their diet? Next, I address concerns surrounding a set of healthy whole grain studies that I’m sure you’ve been hearing about. Are whole grains really healthy? Will they make you live long and prosper? Is there something unique to whole grains we’re missing out on?

Dear Mark: Are Probiotics Useless, Gluten-Free Diets Dangerous, and GMOs Completely and Utterly Safe?

For today’s edition of Dear Mark, I’m answering three questions from a single reader who just read an article from Vice. The article makes pretty bold assertions about topics that have already received a good deal of attention here on the blog. First, are probiotics actually useless? A new study cited in the article seems to suggest so. Next, is your gluten-free diet killing you? That’s what the author of the Vice article says. And finally, have GMO foods been conclusively proven to be safe and indistinguishable from non-GMO foods? Is the debate, more or less, conclusively over?

Let’s discuss:
