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: Bone Broth Edition

With bone broth bars popping up in cities, broth-based cookbooks appearing on Amazon, and grass-fed bone broth now available for order online, hot bone water is experiencing a renaissance. And not just among Primal devotees. Dr. Oz is recommending it as a coffee replacement and Kobe Bryant uses it to support his aging body. The renewed popularity has brought an endless string of questions from readers, and today I’m going to answer some of them. Is bone broth truly a miracle food? Yes, but maybe not for the reason you suspect. Should you make deer bone broth? Yes, with a caveat. Does adding vinegar to your water really increase the mineral content of your broth? Probably not as much as you think. Do beef brisket bones work? Yes. And finally, what are the best parts from each animal for making broth? I give a slightly more detailed answer than “All of them.”

Dear Mark: Sugar in Blackstrap Molasses, Eating Cheat Foods All at Once or in Installments, and Healthy Pooping with a Fused Knee

For today’s edition of Dear Mark, I’m answering three questions. The first one concerns blackstrap molasses, a type of sugar I’ve suggested people eat for its rich mineral content. Does the value of the minerals outweigh the impact of its sugar content? Next, say you’ve got a slice of birthday cake you’re committed to eating. Is it better to eat it all at once or piece it out across multiple days? And third, how can someone who’s unable to squat obtain the benefits of squatting while pooping? In the absence of actual squatting, is there anything a person can do to smooth out the process?

Dear Mark: Healing Broken Bones, and Blended Soups

For today’s edition of Dear Mark, I’m answer two questions. First, is there a way to speed up the healing process after a broken bone? What nutrients should we make sure to consume? Are there supplements we can take, foods we can eat, lifestyle modifications we can make? The next question comes from a reader trying to nurse his grandfather back to health after a bad stroke. Grandpa’s still in the hospital and can only eat through a straw. Are there better options than the tasteless slop, butterscotch pudding, and bad ice cream he’s currently receiving?

Dear Mark: Lead in Crock Pots, Norovirus in Smoked Oysters, and Creatine and Carbs

For today’s edition of Dear Mark, I’m answering three questions from readers. First, what’s the deal with lead in crock pots? Some say lead leaches into the food when we cook with crock pots, while others aren’t so sure. And if the leaching of lead from crock pot ceramics into our food is, indeed, a problem, what equivalent product do I recommend? Next, a new study indicates that human norovirus is highly prevalent in oysters. Should we stop eating the canned smoked oysters from Crown Prince? And finally, do we really need to consume extra carbs with our creatine to get the full benefits?

Dear Mark: Natural Energy Boosters, Designer Fruit, and How to Be Okay

For today’s edition of Dear Mark, I’m answering three of your question, dear readers. First, are there any caffeine-free ways to boost energy during a (really) long workday? Absolutely (but caffeine still might help). Second, what’s the deal with cotton candy grapes, a new designer fruit? Is it just junk food on the vine, or can designer fruits be a healthy part of a Primal eating plan? The last question comes from Shirley, a dedicated weight lifter and macronutrient-counter who’s tired of tracking and planning everything. She just wants to enjoy herself and be content with her body without all the calculation. How can she do it?

Dear Mark: Pegan Dieting and Exercising in Air Pollution

For today’s edition of Dear Mark, I’m answering two questions. The first comes from Lucas, a man whose wife is unable to eat meat without feeling sick to her stomach. As a result, she’s interested in pursuing a Pegan way of eating, or “paleo-vegan.” Is it possible to be healthy while emphasizing plant foods and avoiding most meat? Is there anything she should watch out for? And last but not least, what’s the deal with commuting to work on your bike amidst urban air pollution? We all know that active commutes are supposed to be healthier than riding in a metal box, but do the negatives of breathing all those airborne particulates outweigh the positives of riding your bike? Find out what I think.

Dear Mark: Ketosis and Cancer, Probiotic Dosing Patterns

For today’s edition of Dear Mark, I’m answering two questions. First up, is the ketogenic diet an effective cancer treatment? There’s a lot of hype in the media and online world about ketosis, but what does the research really say? Then, I discuss a few different probiotic dosing patterns. Should you take them every day? Is there a benefit to switching brands from time to time? Should you ever megadose probiotics? How did ancient and preindustrial people “supplement” probiotics?

Dear Mark: Sun Aging Skin, Veggies as Carbs, and What Breaks a Fast

For today’s edition of Dear Mark, I’m answering three questions. First up comes from Carlos, who is worried about the effect of sun exposure on skin aging. Is the type of sun exposure I recommend good for vitamin D levels but bad for the health and appearance of skin? Second, how can someone eat all the vegetables I recommend while keeping their carb intake below acceptable levels? Aren’t veggies really high in carbohydrates? And finally, what “breaks” a fast? How much protein, fat, carbs, and overall calories can a person get away with without shifting completely out of the fasting state?

Dear Mark: Anti-Paleo Guardian Column (Plus, Did Big Brains Need Carbs?)

For today’s edition of Dear Mark, I’m answering one question. First up is the latest anti-paleo piece of clickbait, this time from the Guardian. Apparently the ancestral health movement has had a really bad year or something, and we’re barely hanging on after being dealt a series of devastating blows from the scientific community. Will we make it? Find out below. I also use the original question to springboard into a larger discussion on the new study claiming that carbs were necessary for the evolution of the enormous human brain. The media is selling it as a total refutation of the Primal way of eating, but I’m not so sure. It turns out we have way more in common than you might think from reading the headlines.

Dear Mark: Low-Fat Versus Low-Carb Study and Plain Ol’ Olive Oil

For today’s edition of Dear Mark, I’m answering two questions from readers. First, I field one of the dozens of emails I received concerning the latest low-carb versus low-fat study making the media rounds. The reports have ranged from declarations of low-carb dieting’s imminent death to more reasonable discussions of the actual paper. The Time article actually keeps things closer to the latter, which was nice. For the final question, I discuss the merits of regular old olive oil. Is extra virgin olive oil the only one worth entertaining?
