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...

10 Primal Date Ideas For Every Couple

I know we missed Valentine’s Day, but I’ve always said love cannot be contained. Besides: People are always going on dates. People are always searching for new ways to break out of the regular mold, which is completely understandable. Dates are try-outs. You’re spending time with another person to determine how they fit into your life. Unconventional dates that branch out from “dinner, movie, drinks” into more adventurous, creative realms provide excellent feedback for making that determination.

Dates are also a way for established couples to keep things fresh and exciting, to keep the relationship moving. There’s no better way than to try something new.

As it happens, most work for friends, too.

Now, some of these dates are silly or out-of-left field. Some are more serious. And one is a Primal Costanza date—what not to do. But regardless, they are all worth exploring. And—as always—I’d love to hear what you’d add.

Dear Mark: How Does LDL Even Penetrate the Arteries, New Zealand Farmed Salmon, Elevated Ferritin

For today’s edition of Dear Mark, I’m answering three questions. First, can LDL actually infiltrate the arteries, or is there more to the story? Malcolm Kendrick says there’s more to the story, so I dig into some literature to see if they corroborate his position. Second, is New Zealand farmed salmon good to eat? And finally, what should you do about elevated ferritin levels—and why else might they be elevated if not because of your iron?

Let’s go:

Keto Chicken Pot Pies

Pot pies—like sloppy joes—are a comfort food classic that feeds our nostalgia as well as appetite. Meat and veggies in a creamy sauce that’s topped with a crunchy topping…what’s not to love?

It might seem, however, that pot pie isn’t compatible with a Primal, let alone keto, plan. Au contraire. We’ve serving up a recipe today that turns that assumption on its head. Pot pie is no longer pie in the sky for the keto eater. Enjoy!

Is Keto Bad For Cholesterol?

We’ve all heard the story. Maybe we’ve even been the protagonist.

Person goes full keto. They lose a bunch of weight, normalize their pre-diabetic glucose numbers, resolve their high blood pressure readings, have more energy, feel great, and have nothing but high praise for the new way of eating.

Except for one thing, everything seems perfect: their cholesterol is sky-high. It throws a wrench into the whole operation, installs a raincloud over the procession, spoils their confidence.

“Could I be killing myself?”
