In Vitro Meat

testtubemeatWhen Winston Churchill, in the 1932 essay “Fifty Years Hence,” mused that “we shall escape the absurdity of growing a whole chicken in order to eat the breast or wing by growing these parts separately under a suitable medium,” he may have been more prescient than credited. Alexis Carrel had already been keeping a cultured chunk of chicken heart “alive” in a Pyrex flask for the past twenty years by feeding it nutrients (though Carrel was only interested in whether cell death was inevitable, not whether meat could be grown in a lab for human consumption). Sci-fi author Frederik Pohl was one man who took the idea of in vitro meat seriously enough to write about it – in the novel The Space Merchants, where cultured meat is the primary source of protein. That was science fiction, sure, but most good sci-fi is borne of the author’s honest opinion of what the future might hold and it’s usually inspired by the scientific advancements of the day. And sometimes, science fiction comes true. Like this time.

How to Maintain Muscle While Losing Weight

weightscale muscle loss“Losing weight” is insufficient terminology. It’s too vague, too unspecific. When a person sets out to lose weight, just what are they trying to lose? Bone density? Muscle mass? Organ weight? Of course not – they’re generally looking to lose adipose tissue. People want to burn body fat, and they want to do it without negatively impacting the more beneficial sources of (corporeal) gravitas. Simply put, you want to lose fat, not muscle. The only problem is that the popular methods for shedding weight often result in excessive (but really, any amount is excessive) muscle loss, too. I’m talking, of course, about precisely the practices I rail against in the Primal Blueprint Chronic Cardio, ultra low-cal/low-fat ascetic dieting, and other trappings of Conventional Fitness Wisdom. Granted, adhering to any, individually or in concert, will probably help you lose weight, but a ton of it will come from your lean mass (not to mention bones and organs). That said, if you’re going for skinny-fat chic or the waiflike, undernourished look, feel free to run fifteen miles a day and live off canned tuna and rice cakes. The scale will drop, and you won’t be weighed down by that pesky musculature any longer.

Meat Lover’s Guide to Marinating Meat (plus 10 Primal Marinades)

steakmarinadeA Primal commitment to regular consumption of pastured, organic (expensive/hard-to-find) meats often means buying in bulk when a good price presents itself. Grass-fed steak runs rather pricey, so the average Grok on a budget can’t survive buying a juicy ribeye from Whole Foods every night; he’s got to pick his spots and stock up when he can. If that means buying fifteen pounds of New Zealand lamb leg steaks in a single go just because they dropped to four bucks a pound, so be it. Thus, we’re left with freezers full of identical cuts of steak, roasts, and slabs of meat, along with a serious conundrum: what the heck do we do with all that meat? Maybe good meat can stand on its own merit (along with a bit of salt and pepper), but even the purest of carnivores will eventually tire of eating the same cut prepared the same way, day after day. And if you’ve got picky kids or spouses, forget about serving the same roast or the same chicken thigh over and over. You’ve got to switch flavors up or risk burn out – and possible regression to fast food and frozen dinners.

Enter Primal marinades.

How to Succeed with the Primal Blueprint

So you’ve decided to join the challenge. You’ve created your own Primal Challenge Journal and have publicly stated your goals for the next month. Now what? First things first. You have to know the basics. If you’re new to the Primal Blueprint the following article will be like gold to you. Revisit it again and again until you’ve committed the concepts to memory. The graphs and charts are visual representations of the principles that are at the core of the Primal health philosophy and give you a taste of what it is in my new book, The Primal Blueprint.

You’ve defined the “what”. If your goal is to lose weight, build muscle, increase energy or just generally look and feel healthier these graphics explain the basics of the “how”.

How to Gain Weight and Build Muscle

Muscle 4So you wanna put on some lean muscle mass. And you want to do it within the context of the Primal Blueprint, but aren’t sure where to start. It’s a common question and it’s about time I addressed it head on.

As I’ve made pretty clear, our ultimate goal is to achieve positive gene expression, functional strength, optimum health, and extended longevity. In other words: To make the most out of the particular gene set you inherited. These are my end goals, and I’ve modeled the PB Laws with them in mind. But that doesn’t mean packing on extra muscle can’t happen with additional input. After I retired from a life of chronic cardio and started living Primally, I added 15 pounds of muscle, while keeping low body fat levels without really trying, so it’s absolutely possible for a hardgainer to gain some. The question is how much and at what expense?
