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: PUFA/SFA Swap, Ticks and Meat Allergy, HIIT for Older Men

For today’s edition of Dear Mark, I’m doing three quick topics. First, what are we to make of the studies in which replacing saturated fat and trans-fat with omega-3 and omega-6 polyunsaturated fat seems to reduce heart disease? Second, although red meat is nutrient dense and generally a more interesting option than plain chicken breast, some people have legit red meat allergies (tick-induced or otherwise). What do I think about that and the tick situation in general? And third, is HIIT an effective (and safe) option for middle-aged men?

Male Menopause: What’s Behind Men’s Midlife Health?

It has many names and monikers.

Male menopause.

Andropause.

Age-related testosterone deficiency.

Hypogonadism.

Manopause, my personal favorite.

Although it isn’t as sharply defined as female menopause, male menopause is a catch-all for the gradual cascade of mental and physical health issues that men face as they approach and pass middle age and their testosterone drops. Wherever possible, I will insert “man” puns into the symptoms and conditions. Consider yourself warned.

Dear Mark: Diet to Get Lean, Exercise to Get Healthy?

For today’s edition of Dear Mark, I’ll be discussing the role of exercise alone in weight and fat loss. If it seems like I’ve been harping on this same topic for a couple weeks now, it’s only because it’s so important to identify both the mainstream (“You must exercise ten minutes for each Oreo you eat.”) and alternative misconceptions (“Exercise has no effect on body composition.”) about exercise. Exercise—all by itself—actually can help you lose body fat, even if it has less to do with “burning calories” than other factors.

Let’s take a look:

A Power Yoga Flow to Improve Functional Strength

Today’s post is offered up by the good folks at PaleoHacks.com. I’ve always been a fan of at-home, bodyweight workouts, as many of you know, and this routine is worth adding to the rotation. Enjoy, everyone.

A Power Yoga Flow is just what you need to improve your functional strength, mobility and stability. But you may be wondering: ”What is functional strength?”

Functional strength is just what it sounds like—the strength to function in your daily life. Many of the movements you do regularly require lifting, bending, stepping, squatting, twisting, muscular endurance and more. A lack of functional strength makes life more difficult. You may get fatigued or winded simply by doing everyday tasks. By following a functional strength and mobility sequence like this Power Yoga Flow just a few times per week, you can increase your functional strength.

Dear Mark: Does Physical Activity Affect Obesity Risk?

For today’s edition of Dear Mark, I’m answering one question from a reader. It concerns the effects of physical activity on obesity.

This is an evergreen topic, a constant in the queries I receive. Is exercise necessary for weight loss? Does physical activity improve body weight? Is exercise all about burning calories, or is there something else going on?

Let’s get to it:

Wearable Weights: Are They Worth It?

If you’re looking for an easy way to incorporate a beginning strength training practice (or just a little extra effort) into your exercise routine, wearable weights—which include weighted vests, ankle weights and wrist weights—can seem like a no-brainer. After all, you’re technically investing the same amount of time and doing the same activities but just with more effort and benefit. And you just have to slip them on and go, right?

Not exactly.
