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: 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?

Last week, you guys asked me a ton of questions as part of a contest. Today, I’m going to answer an initial batch. (If you don’t see yours, check back on Mondays to come when I’ll take up others.)

Sixth, is there a trick to beating a weight loss plateau? Seventh, is there a way to make sardines palatable? And eighth, if you can’t walk one day, can you make it up the next?

Dear Mark: Raising HDL Particle Number, Who Should Try Ketones, and Where’s My Keto Energy?

For today’s edition of Dear Mark, I’m answering three questions from readers. First up, what’s the best way to increase your HDL particle count? There are dozens of articles explaining how to reduce LDL-P, but what about HDL-P? Second, are ketones right—or necessary—for everyone? The final question comes from a reader who, despite sticking with the diet for four months, hasn’t felt the fabled “keto energy.” Should she try ketone supplements, give it more time, or what?

Dear Mark: What Does High HDL Mean? and Is Exercise Good or Useless for Weight Loss?

Today’s edition of Dear Mark is a relatively brief two-parter, but it’s a good one. First, I answer a question about HDL. Is higher good? Is higher (sometimes) bad? How does a person make sense of all the seemingly conflicting information? Then I explain how two statements about exercise and weight loss can be simultaneously correct and apparently contradictory. Is weight loss effective or useless for weight loss, or what?

Second, am I worried about Martha Stewart pounding on turkey breast laid between two pieces of Saran Wrap? Third, what’s different about vaporizing cannabis? Is it better than smoking it?

Dear Mark: Protein Powder Dangers, Fermented Polyphenols, Whole Foods’ Farmed Salmon, and K-Cup Bone Broth

For today’s edition of Dear Mark, I’m answering four reader questions. First, a recent NY Times article makes some scary claims about protein powder—and protein in general. Should you worry? Next, what does a study about probiotics and polyphenol absorption mean for probiotics in general? Third, what do I think about Whole Foods’ new farmed salmon, which purports to be way healthier and more sustainable than other farmed salmons? And finally, I discuss K-cup bone broth.

Dear Mark: Vibration Training, Missing Meniscus, and Neuromuscular Electrical Stimulation

For today’s edition of Dear Mark, I’m answering three questions. First, do those whole body vibration training plates provide the kind of instability that I suggest promotes good cartilage function? Second, what can a person with degenerated or missing menisci do about it? What kind of training can work with knees that are missing cartilage? And finally, what’s my opinion of neuromuscular electric stimulation—does it work?
