The Brain Diet:

A few weeks back, at a small research meeting in Toronto, Ontario, my good friend Dr. Alan Logan handed me a book I hadn’t heard of before. “What’s this, Alan...The Brain Diet? Doesn’t sound all that appetizing.” Amused, Dr Logan went on to tell me that I was seeing a sneak peek of his book discussing how nutrition can impact both brain and body health.

What it really takes to get bodybuilding-style lean

Here's a sample diet plan from Christian Thibaudeau, a top strength coach whose methods have heavily influenced our style of training around here (although we do differ from time to time) and who is a high level competitive bodybuilder in Canada. If you're trying to get super-lean, you've got to learn to progressively drop your calories. And Christian's plan illustrates that perfectly.

From platform to stage with Christian Thibaudeau

For years now, there has been a divide in the weight training world. On the one side are those who lift for strength and power: the athletes, the powerlifters, the Olympic lifters. And on the other side are those who lift for looks: the bodybuilders. When one of the best strength coaches in the world crosses that divide, and trades the Olympic platform for the bodybuilding stage, people take notice. And that’s precisely what Christian Thibaudeau has done.

Off-Season Training for Athletes with Eric Cressey

A few months ago when the PN team sat down to put together this library of training programs to integrate with the Precision Nutrition system, we really wanted to make sure that we had something spectacular for our athletes, many of whom compete at the elite level of their sport. So when it finally came time to put together the program to cover off-season training for athletes, we turned to the guy who does it best: Eric Cressey.

Under the bar with Dave Tate

Dave's own history with Precision Nutrition started earlier this year when, after a serious shoulder injury and worries about his cardiovascular health prompted him to change courses, he called JB and asked for help transforming his body and regaining his health. That transformation has been nothing short of amazing.

Chocolate & Tea– Antioxidant benefits

Assessing vs guessing: PN measurements

Often, we beat ourselves up because we think we’re not making progress (in all areas of our lives). Yet, the truth is, in almost every case, we're making tons of progress. We just haven’t tracked it, and so we don’t realize it. PN now has the tool to track and measure your progress.

World’s greatest homemade protein bars?

A few weeks back I popped over to Phil's house for a visit. Hungry, as usual, I pulled open his fridge in search of nourishment.

Fructose – The sweet nectar of body fat?

As a result of fructose becoming such a media hot topic (and the result of this being lots of sound bites with little sensible information), we here at Precision Nutrition decided to set the record straight. So here's our take on this hotly contested carbohydrate.

10% bodyfat or bust…

Dropping body fat isn't really all that difficult. Especially if you're already pretty overfat. Some extra exercise. Less sugary drinks. A bit more protein and healthy fats. You know the drill. However, dropping your body fat to 10% or less is something else entirely. Learn how one Precision Nutrition member did just that.

Nutrigenomics:

Soy: The latest research

If one natural food source were to earn the title of "controversial food of the year" it'd likely be soy. So we turned to the research. We interviewed a host of soy experts on both sides of the fence. And from our research, we wrote this article. Hopefully it helps you sort through the big soy protein controversy, leaving you with some practical strategies for soy consumption.
