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: Omega-3s and Fish Allergies

By now we all know the benefits of fish oil and its omega-3s: lower risk of heart disease, stroke and cancer, less systemic inflammation, lower risk for depression, better skin, and so on. Although fish and fish oil supplements are the best sources for these omega-3 benefits, there are nonetheless scenarios that rule out these sources.

Dear Mark:

I’m sold on the benefits of a Fish Oil Supplement and I’m interested to start taking one. However, I have had serious allergic reactions to Shell Fish in the past, and an allergist has shown me to be reactive to most fish in general. As such I have avoided anything and everything that swims for a very long time. Maybe it’s possible my allergies were due to inflammation caused by my CW diet, but I’m still wary to test my theory now that I’m eating Primal. I feel like I’m missing out on a huge variety of food and supplement options. Question: I know anything can cause an allergic reaction, but is there any scientific basis for Fish Oil Supplements causing allergic reactions in people who have demonstrated allergies to fish/shellfish? And if so, what are my options for proper Omega-3 supplementation?

Weekend Link Love

I must warn you. This week’s linkage is all about food grotesquery, not to be discussed in polite company and certainly NSFV (not suitable for vegetarians)…

35 ingredients in a chicken mcnugget? I’m not the biggest fan of the Eat-This-Not-That guys, but they cut a mean little article on fast food secrets over at Yahoo Health.

I’ve posted about this place before, but this video on the Heart Attack Grill is quite a gut buster.

Some of you probably remember the controversial bacon explosion. In a similar vein, the folks at Smoking Meat Forums just plain violated culinary etiquette with a wad of Jimmy Dean sausage and creativity gone evil.

What I Mean by “Reprogram Your Genes”

From time to time I’ll get a comment from a skeptical reader that says something like, “I don’t think it’s possible to reprogram your genes through diet/lifestyle. Of course our genes are set at birth and our DNA, or program, is copied into every cell of our bodies. You cannot modify or reprogram your genetic code.” I’d like to address this misunderstanding.

One of the best ways to illustrate what I mean by “reprogram your genes” is to use the analogy that Duke University’s Randy Jirtle, Ph.D., uses in the following videos. Think of your genome as being like computer hardware. If you were to program your computer you wouldn’t be changing the hardware, rather, you would be changing the software that tells the computer what to do. So just as we talk about reprogramming or programming a computer and don’t suggest that the hardware itself has changed we likewise can talk about reprogramming our genes without suggesting that the genes have changed. In the case of genes what we are really changing is the epigenome. To quote Dr. Jirtle, “the epigenome would be like the software that tells the computer when to work, how to work and how much.”

Luckily for us our genes are not our destiny. We have immense control through lifestyle behaviors to turn some genes on and other genes off for desired physical results. Watch these videos for it to all come together if it hasn’t already.

Cocoa and Coconut Snacks

Professional endurance athlete Jonas Colting knows a little bit about tapping into his own power and energy. Most of us don’t push our bodies to the limit in the same way an endurance athlete does. For some of us, just getting through a regular day at the office is a test of endurance. Still, power and energy are attractive qualities. Which is probably why a marketing genius attached these terms to almost every product in the constantly expanding protein bar aisle at the grocery store. Energy Bar. Power Bar. Whatever you call it, they often aren’t very healthy and won’t supply you with any enduring power or energy.

Weight Loss Shortcuts: Pills, Suction and Now… Lasers

Imagine a world where you could stroll into a clinic, spend fifteen minutes reading a magazine while a doctor’s assistant points a bizarre contraption at your backside, and skip out the door, down a few thousand bucks and twenty pounds lighter. Provided you had the money and the extra weight, would you do it? Would you be willing to take the ultimate weight loss shortcut? With less invasiveness than liposuction and fewer complications, it would be tough to say no. Just make sure you save money for new pants and a new belt on the same trip.

Eat. Rejoice. Repeat.

Although I haven’t read the book (Eat. Repent. Repeat.), it’s a concept we’re all familiar with. People eat something they know they shouldn’t, self-flagellate and run themselves ragged on the treadmill in penance, only to find themselves in the same boat a few days (or hours) later. Not much of a surprise on that one, is it? I’ll admit I’ve never understood this game, but I see it for the self-perpetuating cycle that it is: an endless rotation of escapism, guilt and punishment. Why do so many people insist upon this transgressive model of eating? And, why, for Pete’s sake, do they think raining retribution on themselves is any way to get back in the saddle?
