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: Social Contact and Neuroplasticity; Extra Protein and Muscle Gain

As you all know, one of my favorite parts of doing this blog is the constant, unyielding, uncompromising feedback I get from readers. When I make a mistake, or overlook a crucial piece of a puzzle, someone tells me where I went wrong or provides that missing piece. For today’s edition of Dear Mark, I’ll be addressing two emails from readers who took me to task for things I missed on this week’s posts.

The first comes from Simon, who had a great suggestion for increasing neuroplasticity. The second comes from Jen, who highlighted a new study shedding light on the effect of extra protein on muscle gains.

Dear Mark: How Often Should I Supplement with Turmeric?

For today’s edition of Dear Mark, I’m talking about turmeric. Last week, I made an off-handed recommendation that people not eat high doses of turmeric, prompting a great question in the comments. Are there actual dangers to turmeric consumption? Is there something you folks should know? Does something perilous lurk within that yellow powder in your cupboard?

Not exactly, but I did make that recommendation for a reason. Let’s find out why:

Dear Mark: Is a High-Carb, Low-Protein Diet Best for Longevity?

For today’s Dear Mark, I’m answering a question about the optimal diet for longevity. An article sent in by a reader claims that a recent mouse study has identified the perfect diet for everyone, but especially for older people: a high-carb, low-protein one. They even manage to throw in some stuff maligning the paleo diet (they just can’t resist).

Find out below if the claim holds water. Let’s go:

Dear Mark: Did Three New Studies Debunk the Primal Blueprint?

For today’s edition of Dear Mark, I’m answering three questions that at first glance appear to cast doubt on some of the founding tenets of the Primal Blueprint. First, did a recent study show that low-carb dieting is no better—and perhaps worse—than low-fat dieting at helping you lose body fat? The second is a two-parter: are we hypocrites for “ignoring” the insulinogenic effects of protein, and does a paleo diet actually abolish the beneficial effects of CrossFit?  And third, a new study found evidence of cereal grain consumption in a group of European hunter-gatherers. What gives?

Dear Mark: Salt Room Therapy; Can’t Sleep After Training

For today’s edition of Dear Mark, I’m answering two questions. First, what’s the deal with salt room therapy? Are there actual benefits, particularly for dermatological and respiratory conditions, to sitting inside a room as aerosolized salt wafts over you? Second, what can a reader do who absolutely can’t get to sleep after training at night? Postworkout insomnia is a real drag, and it will impede your gains, so this is an important topic. Luckily, there are a few things to try.

Dear Mark: Does Cupping Work?; Do I Need More Protein?

For today’s edition of Dear Mark, I’m answering a couple questions from readers. The first one concerns cupping, the controversial therapy used by dozens of Olympians, including most notably Michael Phelps. What does it do, if anything? How does it work, if it even works? And then I discuss the need for increased protein intake in the context of losing lean mass. We want to lose fat, not lean, remember, and there’s evidence that increasing your protein intake can preserve lean muscle. Especially when you’re exercising a ton and eating low-carb.

Dear Mark: Swimming Tips; High Weight, Low Reps vs High Reps, Low Weight

For today’s edition of Dear Mark, I’m answering two questions. First up are some swimming tips for a novice swimmer who read last week’s post and wants to incorporate swimming into the schedule. What strokes to learn? What workouts to try? I also discuss the downsides of chlorinated pools. Next, a new study claims that whether you lift heavy weight for low reps or lift light for high reps has no effect on strength or size, so long as you go to failure. Is this true?

Dear Mark: Dairy Inhibiting Magnesium Absorption, Trampoline Training, and Max Aerobic Heart Rate

For today’s edition of Dear Mark, I’m answering three questions. First, does dairy inhibit magnesium absorption, thus negating the utility of adding blackstrap molasses to milk? There’s a good deal of evidence that points to a probable answer. Next, is mini trampoline training actually good for you, or is it just a silly way to pass the time and look ridiculous (or all of the above)? And finally, how should someone calculate (and train under) their max aerobic heart rate?

Dear Mark: Amino Acid Supplements, Preventing an Infection, and Knee Pain in a Lunging Athlete

For today’s edition of Dear Mark, I’m answering three questions. First, are the amino acid supplements sarcosine, D-serine, and D-cycloserine worth taking? What do they do and who can they help? Next, what should you do to prevent an infection? Besides the regular stuff like vitamin C and vitamin D, is there anything else to take to mitigate the damage and prevent pathogenic incursions? And finally, I field a question from a fencer and martial artist who’s feeling the beginning twinges of knee pain. He leads a lunge-heavy life—it’s an inescapable part of his training—and I offer a few suggestions for limiting the damage.

Dear Mark: How to Eat Blackstrap Molasses; Healthy Whole Grains Studies

For today’s edition of Dear Mark, I’m answering two reader questions. First, I answer a very specific question about blackstrap molasses, that nutrient-dense sweetener with the distinctive taste. How can a person who hates molasses work it into their diet? Next, I address concerns surrounding a set of healthy whole grain studies that I’m sure you’ve been hearing about. Are whole grains really healthy? Will they make you live long and prosper? Is there something unique to whole grains we’re missing out on?
