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’ll be answering your CBD questions from the past few weeks. CBD, or cannabidiol, is exploding in popularity, but there are many unknowns. People have a lot of questions and there aren’t many definitive or comprehensive guides, so today I’ll do my best to make sense of it. We’re all piecing things together based on limited data—which, I suppose, is the fundamental human experience.

While some keto or low-carb proponents claim fiber is useless at best and actively harmful at worst, I come down on the side that says fiber is probably helpful for most people. Some folks have persistently better responses to low- or no-fiber keto diets, and I won’t argue with that—I’ve seen it happen and I’ve read the studies where de-emphasizing fiber can actually improve constipation, for example.
I’ll just say that I have an opposite reaction, and, most importantly, I love eating a variety of plant foods that also happen to contain a ton of great nutrients in addition to fiber.Read More
Some people just don’t do milk.
There are many reasons why. Maybe you have a dairy intolerance. Maybe you don’t like the way cow’s milk tastes. Or maybe you think cow milk is unhealthy.
I won’t contest the reasons why. That’s another topic for another post, and I’ve already covered the most common anti-dairy arguments. If you want to read about my stance on the healthfulness (or lack thereof) of dairy, read what I’ve written about raw milk, cheese, yogurt, and dairy in general. If you want to learn how to identify dairy intolerance, read this.
But the fact is, lots of people either need or want a milk alternative. Water is great to drink, but it’s not the right smoothie substrate, and it can’t replace milk in recipes or coffee drinks. You need something vaguely white and thick enough to pass as milk.
Normally in a post like this, I’d cover all the different varieties and what sets each apart—their strengths and weaknesses, their nutrient profiles, their unhealthy ingredients. And I’ll certainly do that today, but first there’s good news and bad news.Read More
Longtime readers of the blog are so inundated with the latest dietary research and results from years of personal experimentation that they often take the simple, basic dietary truths for granted. But it’s the simple ones that make the most difference. Today I’m going to sift through the knowledge base to winnow out the dietary truths that, while basic, fundamental, and important, are unknown or misinterpreted in the “normal population.” If you think someone you know or care about could learn from this list, send it along.
What follows are some basic dietary truths that everyone needs to understand.Read More
For today’s edition of Dear Mark, I’m responding to four reader comments. First up, if a person can’t eat eggs, doesn’t like liver, but really wants choline, can they just supplement? Second, are a couple handfuls of almonds too much omega-6 for the average person? What if they eat fish? Third, a new study claims to show that keto dieting tanks hepatic insulin sensitivity. What should we make of it? Are we giving ourselves type 2 diabetes by going keto? And fourth, I highlight a great approach to drinking alcohol (and living in general) from one of our readers.

Because humans were hunter-gatherers for hundreds of thousands of years, we evolved to use and favor the diverse plant and rich meat intake of our hunting and foraging history. Farming and its core crops (e.g. grains), by contrast, only came on the scene approximately 10,000 years ago and took at least 8000 of those years to spread across the world. Our evolutionary roots—and residual genetic expectations—favor the nutritional practices of our hunter-gatherer legacy. (For more on the history of the paleo diet, click here.)
The “paleo diet” today looks to the dietary model of our hunter-gatherer ancestors and translates those eating practices to the modern age for the purpose of optimum health.
The paleo diet favors nutrient-dense whole foods and eschews processed food products. Let’s look at the wide variety of flavorful (and healthy) choices within a paleo protocol as well as some basic principles for what to eat and what to avoid. For a PDF print-out of this list, click here.Read More
Absolutely! Anyone can go keto, including vegans. They might not be able to stay vegan, but they can certainly go keto. Nothing stopping them. The more the merrier.
Jokes aside. Can someone go keto while remaining vegan?
That’s a tougher problem. Not intractable. But real tough.
Why is it so hard?Read More
Imagine money is no object. Imagine you wield absolute control over the scientific community and can direct it to run whichever study you desire. If you can dream it up, they’ll get the subjects, produce the money, and make it happen. All you need to come up with is the overarching design. What would you choose? What do you wonder? What questions do you want answered once and for all?
Here’s what I’d choose:Read More
For today’s edition of Dear Mark, I’m answering three questions. You guys had more questions about folate. Since it’s such an important vitamin, I answer those first. Then I discuss the study mentioned in last week’s Dear Mark in which removing polyphenol-rich fruits and vegetables from the diet improved oxidative stress markers instead of worsening them. I got my hands on the full study, so I have more to say on the subject.

Recently, a reader inquired about gamma linolenic acid (GLA) and inflammation. Is GLA everything it’s made out to be? Is it something all of us should add to our diets? Can we obtain it through real foods, or do we need to rely on supplements? There’s certainly a lot of hype about GLA’s ability to heal chronic inflammation and even to facilitate an easier transition into menopause (something I’ll cover more in a follow-up post). For today, let’s take a closer look at GLA and the role it may play in anti-inflammatory nutrition.Read More
