Membership Does Have Its Privileges


It's rare, very rare, to find experts who BOTH walk the walk AND talk the talk. Experts who are down to earth. Experts who spend their free time BOTH in the gym and in the books. Experts who just know their stuff backwards and forwards, and who are willing to share their knowledge with others.

Well, last week, myself and my team had the chance to interview five of them, five of the absolute best. And each of those five interviews will be posted on our precisionnutrition.com site this week, one per day.

If you dont know these people, you can meet them for the first time. And if you do know them, youll learn a little bit more about what makes them tick.

So, who are the experts, and what will they be talking about?
Monday:
Body Transformation for Men, by Carter Schoffer
Tuesday:
Program Design for Beginner Females, by Krista Scott-Dixon
Wednesday:
Bodybuilding, by Christian Thibaudeau
Thursday:
Athletic Preparation, by Eric Cressey

Happy Thanksgiving Everyone!


I just got a great Thanksgiving message from one of our JB.com friends and wanted to share it with you:

Hey John,

I was just thinking about a few people that I should thank on this Thanksgiving, and you're one who's on the top of my list. Though I've never done a consultation with you or anything like that, I own Precision Nutrition, Scrawny to Brawny, and I purchased the S to B Gold Coaching Program. I live my nutritional life by Precision Nutrition, and it's made a big difference in the way I look and feel.

I've also benefitted so much from the numerous articles you have given away on the internet for free. I spent 6 weeks on the Get Shredded Diet recently, and it put me in great shape for a very, very important personal event. It made me feel pretty healthy, too.

It's hard to believe a guy I've never even met has contributed so much to my life. I really appreciate all you've done for me, John. So thanks! I hope you have a great Thanksgiving.

Jim


Thanks, Jim, for the great feedback - and thanks to all of the wonderful JB.com readers and Science Link customers for making this a great year. You're all atop my list of folks to thank this Thanksgiving season as well!

The Metabolism Interview

If you're interested in the metabolism and getting the metabolism advantage, check out this great interview with Chuck Miraz, host of Morehead State University's popular show, Front Page.
The Metabolism Advantage Interview
In this interview I discuss whether or not the metabolism necessarily declines with age and if so, what we can do to prevent it.

Quality of LIfe vs. Longevity - Don't Believe The Hype

The idea that calorie restriction can enhance longevity isn't a new one. Many animal models have demonstrated that reducing calorie intake by 30-50% can dramatically increase lifespan.

While this info is old hat to scientists, calorie restriction was just thrust into the public eye this week with the following New York Times article. Go ahead and pop over to the site and give it a read. But before dropping your calorie intake by 30-50% just yet, consider the following.

First, there are alot of questions left unanswered. Just a few, for example, are:

Does this information translate to humans?
Are there other ways live longer vs. eating 30-50% less?
How exactly does CR work and can we mimic that other ways?
Are there any risks associated with eating this much less?


Second, the current comparisons between a "typical" diet and a calorie restricted one are limited. For example, those eating a "healthy", Precision Nutrition-style diet would be less likely to suffer the same decline and disease that those eating a "typical" diet would face. So yes, if you're going to keep up your typical North American diet and refuse to make improvements, calorie restriction might be for you. But that might not be a choice you have to make.

After all, big calorie restriction isn't easy. As one of the researchers suggested:

"Calorie restriction is doomed to fail, and will make people miserable in the process of attempting it," said Dr. Jay Phelan, an evolutionary biologist at the University of California, Los Angeles, and a co-author of the paper."

In the end, eating well, supplementing intelligently, and subscribing to a life-long exercise program may prove to even more powerful than calorie restriction. And you won't have to suffer the restriction, deprivation, and, well, scrawnyness associated with this approach.

After all, I'm assuming that none of us here want to mimic the physique of Mike Linksvayer, example of a calorie restriction proponent. At 6ft, 135 Mike is severly underweight (certainly a candidate for my Scrawny to Brawny program). Interestingly this low body weight presents its own risks as he ages - studies show that those with low body weight and low muscle mass are at a higher risk for a loss of independence into their elder years due to the natural losses in bone and muscle that occur. So Mike may be healthier than his friends now, but watch out Mike as you age!

And here's another interesting piece of data...studies are showing that the nutritional supplement resveratrol may work through the same pathways as calorie restriction to enhance longetivty. Check this discussion out as well as this one and this one.

So, folks, don't stop eating just yet. Although calorie restriction works in animals, it's not yet proven in humans. And if it does turn out to work in humans, we don't know how powerful the effects will be. But more to the point, who cares when calorie restriction is so difficult and carries its own risks including exchanging quality of life for longevity.

Why not learn the good lifestyle habits associated with smart eating, proper supplementation, and lifelong exercise? That way you can eat, exercise, and be merry while living long and living well.
