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.

A Big Announcement (and Our Keto Team’s Day on Facebook)

I’m not often bowled over. Maybe it’s my age or personality, but I endeavor to take events as information (whether positive or negative) and not get too caught up in the feedback.

Today, however, I’m bowled over—and a little overcome. I’ll admit part of me wanted to title this a “big-ass” announcement, but who knows how Google reads these things….

Let me cut to the chase…

Where I Part Ways with the Popular Keto Movement

The explosive growth of interest in the ketogenic diet has been a net good for the state of nutrition. For one, people have accepted the fact that eating fat won’t kill you, and they’re even getting clued into the benefits of eating it.

But there are places where I part ways with the popular keto movement.

Let me explain….

Is Keto for Everyone? Cautions, Caveats, and Contraindications

In a few months, I’ll be releasing a book extolling the virtues of a ketogenic diet. I’m currently several months into a ketogenic experiment, which is going well. I just wrote a Definitive Guide explaining why you should consider going keto. I’m on record as stating that everyone should dip into ketosis from time to time. You’d think I’d recommend that everyone go keto. Right?

There are caveats. There are contraindications. There are very good reasons for a person not to go keto, or at least to take a few extra precautions. Today, I’m going to tell you when you should exercise particular care when considering a ketogenic diet.

Dear Mark: Keto Follow-Up

For today’s edition of Dear Mark, I’m answering some questions from the comment board of last week’s Definitive Guide to Keto. You folks came up with some great ones. Is counting carbs in non-starchy vegetables still unnecessary on a ketogenic diet? What’s the connection between ketosis and “starvation mode,” and should we be worried? What if you don’t want to lose weight on a ketogenic diet?what modifications should you make? Are you in danger of blowing a breathalyzer test due to ketone metabolites on your breath? Can endurance athletes benefit from keto? Is cyclical ketosis preferable to constant ketosis? Are sugar alcohols ketogenic-friendly?

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: 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?
