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: Rapid Weight Loss

Mark,

 

I’m a big guy (okay, obese, if I’m being honest) who’s getting smaller fast. I adopted the PB a couple weeks ago, and I’ve already dropped twenty pounds, going from 300 to 280. Don’t get me wrong, I’m not complaining. I’m just confused. How does that work? You always hear that initial weight loss for the really overweight is fast, but why? Is it really just water weight? It seems metabolically impossible that I’ve actually burned that much body fat… I can’t help but feel a bit let down if all I’m doing is losing water. If there’s one thing I learned from your writings, it’s weight isn’t just weight (and calories aren’t just calories). So… what gives?

Thanks,

Todd

How to Quit Grains

Yes, they’re inextricably woven into nearly every aspect of our society. Dietary staple, cultural icon, sentimental fodder, patriotic symbol: it’s impossible to get away from them. However, just because they’re ubiquitous in our social environment doesn’t mean they deserve a place on your dinner plate. You know the multitude of reasons to quit grains. How about some strategies for kicking them to the curb?

As much as I condone, cajole and attempt to convince people to give up grains for the sake of their health, I’m not oblivious to the fact that dumping grains can be a tough and sometimes lonely slog. It’s not just the cultural thing either. For most people, physiological and habitual forces are the most demanding aspects. You’ve likely heard the term “carboholic” (used mostly in magazines and Oprah confessions for humorous, normalizing purposes), but there’s genuine truth there. Although I’m not equating the ravages of alcoholism and drug addiction with carb cravings, hard science has something to say about the physiological compulsion associated with dietary sugar and carbs (PDF).

Dear Mark: The Low Carb Flu

Conquering carbs offers a whole constellation of rewards, not the least of which is a steady, brisk energy unlike most people have known before (well, maybe since the whirling age of 10 or so…). People tell me constantly that they can finally make it through the day without being down for the count every midafternoon. They enjoy enough vigor and vitality to weather a whole day’s worth of activity. The busyness of life becomes easier to handle: the energy demands of daily work or business travel, the mayhem and constant commotion of kids, a weekend’s worth of chores and errands, etc. A skipped meal doesn’t suddenly change the agenda to including procuring a bagel or other false pick-me-up. Nonetheless, for some folks, there’s a common, temporary but still bothersome bump in the road on the way to that Primal prize. Though it varies, it often means a couple weeks of mental fuzziness, fog and fatigue. Although your body might be off to the races, your brain can lag behind like a little brother in a stuffed snowsuit. It’s a game of “hey, wait up!”  while the body’s mechanisms and metabolism align themselves. They call it “low carb flu,” and rest assured it’s just as temporary.

Dear Mark,

I just want to know if anyone who has been Primal for some time had any trouble with cognition in the first few weeks. I can hardly think straight, especially after eating, and I am also low on energy. Will this pass??? Besides that, my body feels great!”

What About a Zero Carb Diet?

Zero carb is getting (relatively) popular. A handful of valued MDA forum members eat little-to-no-carb, and several others probably imagine it’s ideal even if they don’t personally follow it. I wanted to address this because there seems to be some confusion as to how a zero carb eating plan relates to the Primal Blueprint eating plan. To begin with: I think zero carb can be a viable option for some, but highly impractical for most. If one had access to and ate different animals, all range fed and without pollutants, and if one ate all offal (and stomach contents) it’s possible to approach zero carb… but again highly impractical. If you really, really love meat and fat and offal, and get genuine enjoyment from eating nothing but meat and fat and offal, have at it. On the other hand, if you are looking for a wider variety – and gustatory enjoyment – of the foods you eat, zero carb may be unenjoyable, impractical, unnecessary, and at worst (if not done just right) downright dangerous.

Let’s take a look at just a few of the reasons why vegetables are a part of The Primal Blueprint:

Weekend Special: Human Foie Gras

Rejoice!

A new clinical study was just released linking a low-carbohydrate diet to reduced liver fat. Get this, though – the scientists actually compared the low-carb diet to a low-calorie diet and found the low-cal diet severely lacking. Their results aren’t surprising, especially to our readers. In fact, we’re almost tempted to put this in the “Duh” files, but these guys seem to be on our side: they went into it with a hypothesis that maybe, just maybe, a low-carb diet could be helpful, and the results speak for themselves. A study that’s actually intended to investigate the advantages of a low-carb diet without the underlying assumption that CW-driven low-cal diets are better? No way we’re passing up a chance to discuss it!

Low Carb Diets Affect Short Term Memory

A soon-to-be published study in Appetite [2009 Feb;52(1):96-103] (but apparently already published online earlier this summer) done by a group at Tufts seems to have “proven” that when you remove carbohydrates for three weeks from the diet of people who have depended on them for decades, you get some short-term memory loss, fuzzy thinking and/or mood swings. In what appears to me to be yet another colossal waste of time and money, the Tufts researchers concluded that “the brain needs glucose for energy, and diets low in carbohydrates can be detrimental to learning, memory and thinking.” What? They got grant money for this? Most of my Primal Blueprint 30-day challengers could have told you that for free! If you understand the power of gene expression and the ability of the human body to acclimate, this study only “proves” what we’ve known for over 100 years.
