Collagen or whey. Which should you choose? For years, collagen/gelatin was maligned by bodybuilding ...
There are many meaningful reasons people go Primal: they want to improve their fitness, increase their longevity, feel younger, reverse lifestyle conditions, heal hormonal imbalances, enhance fertility, get off prescription medications, and lose fat. With regard to losing fat, some want to lose a good deal of it—to significantly alter their body composition. This goal, while it has the power to shift one’s entire health trajectory (not to mention life experience) may also be the most likely to come with unforeseen, even undesired results. I’m talking particularly about those who undergo dramatic transformations—the kind that can leave them feeling incredible, enjoying vitality, and (in particular) looking substantially different.Read More
The entire premise of the Primal Blueprint is enabling you to be the architect of your health and happiness. If we can identify the environmental triggers and selective pressures under which the human genome developed, we’ll have a great roadmap for engineering our optimal lifestyle. And for the most part, it works. Not everyone will get the exact body they desire. You won’t all lose every extra pound. I can’t guarantee a six pack or a complete eradication of baby weight. But all in all, eating and living this way seems to produce good results. You can, it seems, affect your health, body composition, and fitness.
But genes still matter. And there’s a large trove of evidence showing that a person’s genetics are really good at predicting their risk of obesity.Read More
Every day we’re barraged by “good ideas”—all the things we should be doing with our lives and could start doing today if we really cared enough. Too much advice can overwhelm us, and, more importantly, it can inflate the power of “should.” It can cement an insidious (and, in my experience, ineffective) framework in our minds. We risk framing every choice—from work to pleasure—as an obligation. Doing so burdens life with a constant sense of onus, constraint and deprivation—not exactly the stuff of grand motivation. In my experience, we aren’t in for much fun or long-term success with that brand of approach. Luckily, there’s a better way to talk to ourselves.Read More
If you follow health news, you might be thinking exercise doesn’t matter when you’re trying to lose weight. Vox just published a big piece showing how useless exercise alone is for weight loss. The NY Times says “eating less” is way more effective than “exercising more.” Obesity researchers like Gary Taubes and Yoni Freedhoff—who don’t agree on much else—both think using exercise to fix obesity is futile. I’ve always said that 80% of your body composition is determined by your diet, not how you exercise. And everyone knows it’s really hard, bordering on impossible, to out exercise a bad diet. You might be able to out exercise a bad diet if all you care about is abs and race times and make it your job, but eventually your poor health will catch up with you.
That doesn’t mean exercise doesn’t matter for weight loss, though. It does.Read More
We’ve heard it a million times: “Eat a well-balanced diet with everything in moderation.” After all these decades of clear failure, it’s a hazy cliché still delivered by physicians, dietitians and nutritional “experts” with earnest assurance. The same goes for exercise and stress. Moderate amounts of stress are okay, moderate cardiovascular work is good, etc. We accept the concept of moderation so readily, I think, because it sounds so rational and simple. If we follow common sense, moderation suggests, we’ll be fine. But if it were that easy, most people would be healthy—and statistics on the rising rates of obesity and chronic illness tell us otherwise. So what’s the problem?Read More
For today’s edition of Dear Mark, I’m answer two questions from readers. First, does Bikram yoga qualify as sprinting or high intensity training? It’s certainly intense, and it’ll make you sweat bullets and work hard to the point of nausea, but does it actually accomplish the same training effects as sprinting or intervals? Find out down below. Next, you often hear that body fat is the main repository for environmental toxins. This is true, but does that mean the body “holds on” to body fat to prevent systemic dispersal of the toxins it contains? Can stored toxins make losing body fat harder that it already is?
Let’s go:Read More
