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...

Does Vegetarian Collagen Exist?

I’ll start with the bad news: There are no vegetarian collagen sources. Every collagen supplement you see on the shelf came from a living organism. Though somewhere down the line someone will probably grow legitimate collagen in a lab setting, it’s not available today or for the foreseeable future.

Now, some good news: Vegans and vegetarians probably need less dietary collagen than the average meat eater or Primal eater because a major reason omnivores need collagen is to balance out all the muscle meat we eat. When we metabolize methionine, an amino acid found abundantly in muscle meat, we burn through glycine, an amino acid found abundantly in collagen. If you’re not eating muscle meat, you don’t need as much glycine to balance out your diet, but it’s still a dietary necessity.

Dear Mark: Air-Frying, “Primal” Vegan-ish, Perfect Heath Diet, and Bad Rep or Rap

For today’s edition of Dear Mark, I’m answering four questions. First, is air-frying gentler than deep-frying? Does it produce less acrylamide? Second, what do I think of a reader’s Primal-style plant-based way of eating? It’s actually quite good. Third, why didn’t I mention the Perfect Health Diet in last week’s post on top trending diets? And last, did I make a typo or grammatical error when I wrote “bad rap”?

Let’s find out:

Can a Vegan Go Keto?

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?

Dear Mark: Desert Island Cookware, Supplement Sources, Bulk Frying Oil, B12 on Keto Vegetarian, and Streamlining the Day

For today’s edition of Dear Mark, I’m answering 5 questions from readers. First, I give my desert island cookware material—the type of pan I’d choose if I could only have one. Next, I explain whether carnosine, creatine, and taurine supplements are suitable for vegetarians. After that, I give a good option for bulk frying oil that’s safe and won’t break the bank. Fourth, I explain how you can get enough B12 on a keto vegetarian diet (and it’s not that difficult at all). And finally, I explain how a small change can have huge effects on the quality of one’s life.

How to Do Keto As a Vegetarian

This is one of the most common queries I receive: How do I go keto as a vegetarian?

One way to go keto as a vegetarian is to stop being vegetarian. You begin as a vegetarian, make the conscious decision to go keto, and then cease vegetarianism. Seriously, just try it out. A little animal won’t hurt you. Promise.

Okay, jokes aside: How do you go keto while remaining vegetarian?

Once you let the dust settle and consider the proposition with a calm, clear mind, going keto as a vegetarian isn’t all that outlandish.

What Primal Types Can Learn from Plant-Based Diets (and Dieters)

I joke around a lot and give them hell, but I have love and respect for plant-based diets and the people who eat them. These folks come at health from an entirely different place, and, it’s true, I don’t think their diets are optimal. I think they get a lot wrong. They often misconstrue what Primal is all about. I’ve even received threats from some of the less grounded members of the community, though I know that these are the outliers, the extremists, and I never took them seriously.

But…I’d also suggest plant-based dieters get a lot right. More than you’d think.

14 Weird Plant Bits and Where to Find Them: Foraging Ethnic Markets

Five years ago, I wrote about all the odd animal bits one can find at ethnic markets. I procured and photographed the blood, the guts, the tendon, the tripe, the tails and heads and feet and all the other weird things you can and should eat—meaty bits you won’t find in the local Whole Foods.

Today, I’m going to talk about the weird plant bits available in ethnic markets—spices, greens, roots, noodles, and fermented things.

Dear Mark: Vegetarianism Causes Cancer?; Glucosamine Useless?; Decision Fatigue Debunked?

For today’s edition of Dear Mark, I’m answer three questions. First, does long-term vegetarianism cause cancer or alter our genetic code? Some media coverage of the latest vegetarianism study seemed to suggest as much. Next, is glucosamine just totally useless if you’re not going to fork out a ton of money for pharmaceutical grade stuff? Maybe not, but let’s find out. And finally, I’ve written about decision fatigue a couple times before. What’s my take on the new research seeming to debunk one of the central concepts supporting it—ego depletion/finite willpower?

17 Primal Tips for Vegans and Vegetarians

We all know vegetarians and vegans. And while we have our differences, they are our friends, our family, our partners, our spouses, even our children. We all have people in our lives who avoid meat and/or animal products in general for multiple reasons—health, ethics, the environment, squeamishness, animal welfare—but we care about them. We also subscribe, with varying degrees of rigidity, to an eating philosophy based on the nutritional importance of animal foods. How do we reconcile these competing loyalties? Should we give up on them? Are they a lost cause? Should we simply wait for them to come limping toward us with sallow skin and low muscle tone? I kid, of course. We should absolutely help where and when we can.

Yet telling them to “just eat meat” doesn’t work. If anything, it’s counterproductive. Instead, we can offer productive, legitimately helpful advice from a Primal perspective. Like:

Dear Mark: Foods for a One-Year-Old, Vegan to Primal, and Low-Carb Failing Fibromyalgia

For today’s edition of Dear Mark, I’m answering three reader questions. The first comes from Chris, who’s a little worried his one-year-old isn’t eating a wide enough variety of foods. As it turns out, he doesn’t need to worry, though I do offer a few suggestions for foods to include or offer. Next, how should Verria, a long-time vegan, transition to Primal? Is there anything to watch out for? What physiological and psychological issues will Anita have to face and overcome? And finally, what tips do I have for a fibromyalgia patient whose condition hasn’t improved on a strict very low-carb, high-fat diet?
