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: Metformin Side Effects, Kraft Heinz Deal Questions

For today’s edition of Dear Mark, I’m answering a few questions from readers. First, the diabetes drug metformin looks like a “wonder” drug, even (or especially) for non-diabetics. Are there any known side effects? Is there anything we should watch out for?

Second, I address some of the concerns and criticisms shared in response to the Kraft Heinz announcement post.

Holiday Eating: Considerations for Keto and Primal Types

‘Tis the season… for wondering “Seriously, what the heck am I going eat this holiday??”

I’m guessing that most Mark’s Daily Apple readers can relate to the angst that comes with trying to be a “healthy person” during the holiday season. Are you going to indulge? How much? How will you feel physically and mentally if you do? How will other people behave if you don’t?

Particularly if you’re somewhat new to a Primal lifestyle, it can be hard to figure out what will be best for you—and keto comes with a whole additional set of considerations. Compared to a more general Primal way of eating, keto requires stricter adherence to carbohydrate limitation. Moreover, it is possible to measure your ketone levels and tell objectively whether you have crossed the line (not that you have to do so). If ketosis is your goal, there is no chalking up that chocolate pecan pie to the 80/20 principle and being on your merry way.

7 Herbal Alternatives to HRT

For many women, menopause can introduce new health challenges. In addition to the symptoms that perturb basic quality of life like hot flashes, headaches, night sweats, and irritability, menopause is also associated with higher risk for serious health concerns like osteoporosis, cognitive decline, and metabolic syndrome. This has made the standard treatment for menopause—hormone replacement therapy, or HRT—a multi-billion dollar business.

A few weeks ago, I explored the benefits and risks of HRT. It has its merits certainly, but it’s not for everyone. Today’s post is for those people. Say you’ve waded through the morass of HRT research and would prefer a different route. Or maybe you’ve actually tried conventional or bioidentical HRT and found it just didn’t work for you. Whatever the reason, you’re probably interested in using “natural” products if you can swing it and if it’ll actually help.

Dear Mark: Oxidative Priority Follow-up

Last week, Craig Emmerich graced us with a great post on the oxidative priority of various dietary fuel sources, namely fats, carbohydrates, and protein.

If you haven’t had the chance to read through Craig’s post, definitely do. The visuals really drive home the point of fuel priority. Visuals appeal to me. They have a way of sticking with you, and there’s a power in recalling them when you’re making daily choices.

Today, I’m going through and answering some of the questions you folks had in the comment board.

Oxidative Priority: Dietary Fuels To the Body

Today’s guest post is generously offered up by Craig Emmerich, husband to—and co-author with—the queen of keto herself, Maria Emmerich. Enjoy!

When we consume macro nutrients, our bodies go through a priority for dealing with them. This priority can be very useful in understanding how our bodies work and how to leverage it for losing weight.

The body doesn’t like having an oversaturation of fuel in the blood at any time. It tightly manages the fuels to avoid dangerous situations like hyperglycemia or blood glucose that is too high. But it also manages and controls other fuels like ketones (beta hydroxybutyrate or BHB levels) and fats (free fatty acids or FFA and triglycerides) to keep them under control and not oversaturate the blood with fuel.
