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’m answering several questions drawn from the comment board of last week’s post on fasting vs carb restriction. First, how do I square my recommendations with the successful reports of potato dieters losing weight on a high-carb tuber diet? Second, is Leangains optimal for mass gain? Third, how do I use extra virgin olive oil, butter, and ghee? Fourth, could exogenous ketones help a man with dementia, MS, and seizures? Fifth, how should a woman with stalled weight loss integrate fasting?

Both fasting and carb-restriction appear to operate along similar physiological pathways. Both lower carbs. Both increase fat-adaptation. Both have the potential to get you into ketosis. Both lower insulin and blood sugar.
But is one better than the other? Are there certain scenarios in which an intermittent fasting protocol works better than a low-carb diet, and vice versa?
Let’s find out if the distinction matters.
And what scenarios are most impacted by any difference.Read More
I’ve written about what to eat. I’ve written about what not to eat. I’ve even discussed the benefits of occasionally eating things you “shouldn’t eat.” I’ve written about skipping breakfast, eating a big lunch, and skipping entire days of meals altogether. I’ve discussed sleeping low (carb) and punctuating a low-carb diet with occasional high-carb refeeds. But I haven’t written very much about when to eat.
I won’t tell you when to eat. There are many paths. You must find the one that takes you to your goal. But there are some physiological “truths” that impact how we process food depending on what’s happening in our lives which seem to apply to all humans. I’ll discuss several ways to think about meal timing, and then you can decide which concepts make sense for you and your life.Read More
For today’s edition of Dear Mark, I’m answering three questions from readers. First, what’s the deal with IGF-1, growth hormone, and intermittent fasting? Some people say fasting increases growth hormones, while others say it decreases them. Who’s right? And what’s it all mean for our health? Next, how can a former CrossFitter ensure she’s maintaining her former fitness levels? And finally, what’s my take on Barre training and other “feminine” training schools?

Men I know. I am one, after all. Have been for many years. For the most part, I enjoy it. It’s worked out really well for me. I don’t find it particularly difficult to be a man. Once I dialed in the basics of this Primal stuff, my health improved and my fitness became more well-rounded and applicable to the things I enjoyed doing. I haven’t struggled much. But many people do. And while the majority of Primal advice is geared toward humans in general, I’ll just get this out of the way early: These “men’s tips” all apply to many women, too. And many of the “women’s tips” from last week’s post also apply to men. But ignoring the gender-specificity of general trends serves no one. Everyone has the capacity for competitiveness; men tend to have more. Both genders can benefit from fasting, but women are more likely to have negative responses. Men and women both need sleep; lack of it hits women harder. That’s all. As always, if you recognize yourself in these tips, go for it!Read More
Look: I’m a man. I’ve lived a different experience than the average woman, with totally different equipment and different concentrations of hormones coursing through my body. But I have a daughter and a wife and a good head on my shoulders that’s spent the last 30 years thinking about health, nutrition, and fitness for humans, so I have a few things to offer.
So let’s get right down to today’s post. What follows are 12 tips for Primal women. Or any woman, really.
(Men, too: if some of the things mentioned in today’s post aren’t working for you, and the tips seem to apply, go for it!)Read More
