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: Hiking and Body Composition, Hiding Liver, Unconventional Testosterone Boosters, Cooked/Cooled/Reheated Potatoes, and Sirtuins

For today’s edition of Dear Mark, I’m answering five questions from readers. First up, why isn’t hiking giving one reader the shifts in body comp they expected? Two, is there actually a way to mask the flavor of liver? Then I discuss a few unconventional testosterone boosters, followed by a brief treatment of the cooked, then cooled, then reheated potato. And finally, are there any dietary activators of sirtuin proteins?

Dear Mark: Alcohol and LDL, Liverwurst, Coffee and Milk, Kid Snacks, and High Carb Questions

For today’s edition of Dear Mark, I’m answering 14 questions. The first concerns the effect of alcohol intake on LDL. Does it increase it or lower it (or both)? Next, what’s the best liverwurst to eat? After that, I discuss whether drinking coffee with milk makes the coffee antioxidants useless, followed by a quick list of good snacks for kids. The last ten questions concern cycling high-carb feeds on low-carb diets. They all come from one reader, and they’re very specific and well-constructed.

Dear Mark: Raw Mushrooms, Tom Brady’s Diet, and Beta-Glucan Alternatives

For today’s edition of Dear Mark, I’m answering three questions. First, are raw mushrooms safe to eat? Are there toxins? Are there any other issues to consider? Second, what’s the deal with Tom Brady’s diet and lifestyle? It seems healthy enough, but there are some unanswered questions, too.

Dear Mark: That New Cholesterol-Lowering Drug Study

For today’s edition of Dear Mark, I’m answering one question. It’s a good one. A reader (many, actually) wrote in to get my opinion on the latest blockbuster cholesterol-lowering drug. A new study appears to show that the drug in question—Repatha—reduced LDL to unprecedented levels and protected patients against the primary cardiovascular disease endpoints they were measuring. What does it all mean? Should we all start taking Repatha?

Dear Mark: Infrared Sauna Roundup

After last week’s post on infrared saunas, people asked some good questions. For today’s edition of Dear Mark, I’m answering a few of them. First up, can infrared saunas harm male fertility? After all, they do penetrate the skin and raise body temperature, which is a no-no for sperm. Next, infrared saunas induce lots of sweating, and sweat contains bioaccumulated toxins like BPA and heavy metals. Can infrared saunas help us shed these toxins? Finally, are infrared-emitting blankets and other “topical” infrared products effective alternatives to infrared saunas?

Next, I explain why people with sleep apnea often grind their teeth, and mention an nutritional factor that might also cause grinding. Third, can you ferment frozen vegetables? Should you ferment frozen vegetables? And fourth, is fermented food safe while breastfeeding?

Dear Mark: Fasting Followup

For today’s edition of Dear Mark, I’m answering questions from the comment section of last week’s fasting post. You guys brought up some great points, and I’ll be addressing some of them. First up, do you need to follow a vegan diet to maintain the health benefits of long fasts? Second, I give a tip or two for appetite suppression during the fast. Then I discuss my definition of a long fast, the potential effect of fasting on gut bacteria (and whether we should consume prebiotics and probiotics while fasting), the reason why fasting makes some people have short fuses, and whether green tea k0mbucha breaks the fast.

Dear Mark: Alternative Therapies Follow-up

For today’s edition of Dear Mark, I’m answering four questions from last week’s “Alternative Therapies” comment board. I asked you for questions and comments about other potential therapies, and you all put in good work. First, I address that oldest of home remedies: chicken soup. Does it actually cure? Next, I discuss supplementing with humic and fulvic acid. Can the byproducts of rotting plants and mud improve your health? After that, I quickly address a question about the psychiatric merits of psychedelic therapy. I end with a discussion of the merits (or lack thereof) of pet-assisted therapy.

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.
