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: Fat Gain on a Ketogenic Diet; Dandruff and an Itchy Scalp

For today’s edition of Dear Mark, we’ve got a two-parter. First up, I respond to a comment from last week’s Weekend Link Love concerning fat gain and lean mass loss in taekwondo athletes on a ketogenic diet. Did the athletes actually get fatter and lose muscle on their diet, even as performance improved? After that, I discuss what to do about dandruff and an itchy scalp. There may be no silver bullet against the common malady known as dandruff, but there are a few things you can try and one in particular that looks quite promising.

Let’s go:

Dear Mark: Red Meat and Breast Cancer, Net Carbs, and Solutions for Excess, Unavoidable Sun

For today’s Dear Mark, we’ve got a three-parter. First up, I discuss the latest study claiming that red meat will kill us all. Or maybe it’ll be killing roughly half of us all, seeing as how this paper concerns red meat and women’s breast cancer risk. Next, I give my position on the “net carbs” issue. Do we subtract fiber, leave it as is, or do something else entirely? And finally, I talk a lot about the importance of getting enough sunlight. But what happens when getting enough sun isn’t the problem? What can an outdoor worker do about too much sun?

Let’s go:

We Don’t Know What Constitutes a True Paleo Diet

Critics often lambast the Primal Blueprint and other ancestral/paleo ways of eating for what they see as fatal flaws:

First, that we don’t know what our ancestors were truly eating.

Second, that there wasn’t just one paleo diet.

Third, that even if we could know exactly what our ancestors were eating, it doesn’t mean those foods were the ideal foods; they were trying to eat whatever was available, not whatever was most nutritious or synergistic with their genome.

5 Things People Assume About Me That Are Wrong

As Mark’s Daily Apple and the Primal community have grown in popularity, I hear a lot of stuff bandied about. Some of it is positive, some negative, and that’s to be expected. You can’t please everyone – I would probably be surprised if no one ever criticized me. However, I’ve noticed that for whatever reason, some people have a skewed perception of my opinion on certain issues. Maybe it’s my fault for not being more clear. Maybe they just haven’t plumbed the depths of MDA (I don’t blame them; it’s got some deep archives) to find the truth, instead going on what someone else told them. But whatever the reason, I have an obligation to set the record straight. I don’t want people getting the wrong idea about me or my ideas.

In this post, I’m going to describe five common misinterpretations about me and then explain where I truly stand. You may still disagree with me. That’s cool. At least then you’ll be able to criticize me for what I actually said or wrote.

So, what are some things people assume about me that are wrong?

Dear Mark: Does Eating a Low Carb Diet Cause Insulin Resistance?

Despite all the success you might have had with the Primal way of life, doubts can still nag at you. Maybe it’s something you read, or something someone said to you, or a disapproving glance or offhand comment from a person you otherwise respect, but it’s pretty common when you’re doing something, like giving up grains, avoiding processed food, or eating animal fat, that challenges deeply-and-widely held beliefs about health and wellness. It doesn’t really even matter that you’re losing weight or seem to be thriving; you may still have questions. That’s healthy and smart, and it’s totally natural.
