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...

Long Fasts: Worth the Risk?

Intermittent fasting, schmittermittent schmasting. The hot new trend is the extended fast—eating nothing and drinking only non-caloric beverages for no less than three days and often as many as 30-40 days. A mere compressed eating window this isn’t.

If fasting for more than three days sounds riskier than just skipping breakfast, you’re right. Long fasts can get you into trouble. They’re a big commitment. You shouldn’t just stumble into one because it sounds interesting or some guy on your Twitter feed wrote about it.

Some Primal Answers for Kids’ Problem Behaviors

Last week, Chris Kresser wrote a great article discussing the emerging—and likely causative—link between poor gut health and childhood misbehavior. He explained potential mechanisms for the association, as well as solutions to counter it.

But as any parent knows, getting a picky child to adopt your arsenal of perfect gut-supporting foods and supplements isn’t always easy. Not every kid immersed in the righteous anger of the terrible twos will stop what he’s doing to drink sauerkraut juice, nibble on kimchi, take resistant starch, drink kefir and bone broth.. It’s certainly a major part of the problem and the solution, but are there any other dietary causes? What else can a parent try to stem the flood of tantrums?

8 Alternative Therapies Worth Considering

Here at Mark’s Daily Apple, I avoid writing off anything without first investigating it. I keep one foot in the “alternative” health world and one in the “conventional” realm, making sure to maintain a skeptical—but openminded—stance on everything. There’s no other way to do it, if you’re honest. At least as far as I can tell.

No, not every alternative therapy works. A lot of it is pure hogwash. But whether we’re talking about off-label uses of conventional drugs and illegal drugs, natural pharmacological agents, or downright outlandish-sounding interventions, some therapies are worth considering. Not trying, necessarily. Considering.

A Primal Look at Gestational Diabetes

Every pregnant woman I’ve ever known has hated the oral glucose tolerance test. Yet, they still do it. Drinking a tall glass of sickly sweet orange-flavored glucose water on an empty stomach is thoroughly disgusting, but it, apparently, offers a rare and valuable glimpse into the state of a woman’s perinatal health.

What they’re testing for is gestational diabetes mellitus—a variant of diabetes characterized by pancreatic insufficiency during pregnancy.

Dear Mark: Hydroponic vs. Regular Vegetables; Lowering Blood Pressure Without Meds

For today’s edition of Dear Mark, I’m answering two questions. First up, do the nutrient contents of hydroponic produce differ from soil-grown produce? If so, in what way? Then I give a few (somehwat unprompted) tips for lowering blood pressure without meds. While meds can and do help people overcome or mitigate hypertension, we should apply other options. What are these possibilities?

Dear Mark: Steak Satiety vs Ground Beef Satiety; Maca and Cacao During Fasts; Nut Butters, and Post-work Workouts

For today’s edition of Dear Mark, I’m answering four questions from readers. First, why might a pound of ground beef induce less satiation than a pound of steak? Second, can you take maca root and cacao powder during a fast without breaking it? Third, what’s my take on nut butters? Good kitchen allies or too much of a good thing—or both? And finally, I give a few tips for someone who wants to train more regularly but can’t find the energy required after work.
