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.

Primal Sloppy Joes

Nothing says comfort food quite like sloppy joes. The go-to of potlucks and family dinners for generations, they’ve got the tangy and hearty flavor even kids gravitate to. Many versions, including canned sauces, however, contain added sugars or even high fructose corn syrup—such a shame, since the basic ingredients of sloppy joes need no sweeteners when done right.

Bring this classic back to your healthy menu with this recipe for delicious sloppy joe meat sauce—and the grain-free buns to deliver all the goodness. Enjoy!

Does Vegetarian Collagen Exist?

I’ll start with the bad news: There are no vegetarian collagen sources. Every collagen supplement you see on the shelf came from a living organism. Though somewhere down the line someone will probably grow legitimate collagen in a lab setting, it’s not available today or for the foreseeable future.

Now, some good news: Vegans and vegetarians probably need less dietary collagen than the average meat eater or Primal eater because a major reason omnivores need collagen is to balance out all the muscle meat we eat. When we metabolize methionine, an amino acid found abundantly in muscle meat, we burn through glycine, an amino acid found abundantly in collagen. If you’re not eating muscle meat, you don’t need as much glycine to balance out your diet, but it’s still a dietary necessity.

Dear Mark: Iron Followup

Last week’s post on iron levels got a big response and garnered a ton of questions from you guys. Today, I’m going to clarify a few things and answer as many questions as I can. First, do iron and ferritin levels mean different things for men and women? If so, how do those differences manifest? What about premenopausal women vs postmenopausal women? Second, what do we make of the fact that ferritin is also increased in times of inflammation? Is there a way to distinguish between elevated ferritin caused by inflammation and elevated ferritin caused by high iron? Third, is desiccated liver a good option for liver haters? And finally, I share some exciting plague news.

Good morning, folks. After a awesome week (and weekend) taking over the Whole30® Recipes Instagram (you can still check out all the great videos, tips and recipes I shared here), my team and I are taking a breather.

Thanks to Jessica Gouthro of PaleoHacks for these awesome suggestions, and let us know which you’ll be adding to your routine. 

Working at your desk all day doesn’t have to mean poor posture and an achy body. Whether you sit or stand at work, remaining sedentary for hours takes its toll on the body. After just a few hours, your body will begin to stiffen, your lower back will ache, and you’ll grow sluggish. (For a printable PDF version with photos, click here.)
