Tea can mean a lot of different plants. There’s maté, the bitter South American shrub steeped in boiling water to extract the caffeine-like compounds contained within. There’s rooibos, the “red tea” made from a polyphenol-rich bush native to South Africa. There’s coca, the South American plant also used to make cocaine. There are the unnamed wild bitter root and herb teas used by the Maasai, the evergreen tip teas used by American natives to obtain vitamin C, the nettleleaf teas used across Europe.
For today’s post, I’m focusing on the actual tea plant—Camellia sinensis. All of the classic teas come from the same basic plant; the differences lie in how they’re processed after harvest. Most tea undergoes controlled oxidation to develop flavor and different bioactive compounds. The more oxidized, the darker the tea. The less oxidized, the lighter.
I’m also going to focus on the health benefits of tea, rather than get into the nitty gritty of tea grading, the endless bespoke varieties, the optimum temperature—tea expert stuff. I enjoy tea, but I’m not a connoisseur. I can tell you about the health effects, and I imagine that’s what most of you are here for anyway.Read More
As Primal enthusiasts know, sprinting is an essential element to leading an optimally fit life. After all, it’s one of the 10 Primal Blueprint Laws, and perhaps the quintessential anti-aging activity. Brief, explosive all-out sprints are the single best activity to promote rapid reduction of excess body fat, achieve fitness breakthroughs, flood the bloodstream with anti-aging hormones like testosterone and human growth hormone, and boost neuron function in the brain. Even a very brief sprint session has a profound effect on your metabolic and hormonal function for hours and days afterward, sending what Paleo movement pioneer Dr. Art DeVany calls a “renewal signal” to your genes.Read More
Now that you’ve absorbed the rationale and benefits to add sprinting to your fitness program with Part One of the Definitive Guide To Sprinting, let’s get into the details of how to conduct a great workout. The following five guidelines are presented in logical succession, so you can refer to them frequently and ensure a safe, effective sprint workout. I’ll also share a few sprint workouts you can do anytime, including my own sprint workout routine. Remember, it’s all about going big…and then going home to get on with an awesome life.
Let’s get started….
One of the most common questions I get is “Does [x] break a fast?”
What they’re really inquiring about is: “Does this interfere with, negate, or nullify the benefits of fasting?”
These benefits include:
Ketosis: Fasting is the quickest way to get into ketosis, an metabolic state characterized by increasing fat burning, fat adaptation, and—in some people—improved cognitive function.
Fat Loss: When you’re fasting, you’re not eating, and not eating is the best way to force your body to burn the fat it already possesses. Fasting also means no additional calories are coming in, and many people find that fasting is a great way to control their calorie intake.
Autophagy: Autophagy, or “self-eating,” is the process by which our cells prune damaged components, maintain proper function, and keep aging at bay. Fasting triggers autophagy. Breaking the fast will stop autophagy.
Let’s go through the most popular queries one by one and figure out how each one affects an intermittent fast. (For questions about what supplements break a fast, check out my post, “What Breaks a Fast: Supplements Edition.”)Read More
Biological systems are self-maintaining. They have to be. We don’t have maintenance workers, mechanics, troubleshooters that can “take a look inside” and make sure everything’s running smoothly. Doctors perform a kind of biological maintenance, but even they are working blind from the outside.
No, for life to sustain itself, it has to perform automatic maintenance work on its cells, tissues, organs, and biological processes. One of the most important types of biological maintenance is a process called autophagy.
Autophagy: the word comes from the Greek for “self-eating,” and that’s a very accurate description: Autophagy is when a cell consumes the parts of itself that are damaged or malfunctioning. Lysosomes—members of the innate immune system that also degrade pathogens—degrade the damaged cellular material, making it available for energy and other metabolites. It’s cellular pruning, and it’s an important part of staving off the worst parts of the aging process.Read More
Metabolic flexibility is the capacity to match fuel oxidation to fuel availability—or switch between burning carbs and burning fat. Someone with great metabolic flexibility can burn carbs when they eat them. They can burn fat when they eat it (or when they don’t eat at all). They can switch between carbohydrate metabolism and fat metabolism with relative ease. All those people who can “eat whatever they want” most likely have excellent metabolic flexibility. So, why does it really matter, and how does it happen? Let’s get into the weeds today.Read More
Cold is really catching these days. Aubrey Marcus, whom I recently filmed a nice podcast with, was asked about his winning daily behaviors on another show. The very first thing he mentioned was “exposure to cold.” His practice is finishing his morning shower with a three-minute stint at full cold setting. He mentioned the hormonal benefits but also the mental edge he gets from psyching up and accepting the challenge instead of wimping out. He also cited research that people who engage in therapeutic cold exposure catch fewer upper respiratory infections. Hence, like many other elements of conventional wisdom, the old wives tale is backwards. Of course, we are talking about acute and optimal duration cold exposure, not prolonged exposure to elements that weaken your resistance and contribute to immune disturbances.
As with keto, there’s much more to be learned in this burgeoning field before we can operate in definitive (hence today’s title). Today, however, I’ll expose you (the first of more double entendrés to be on the lookout for) to important concepts and best practices so that you may enjoy the vaunted benefits and avoid some of the negative effects of going about cold exposure wrong.Read More
Ah, chocolate. What a life.
According to the Aztecs, the great feathered serpent god of wisdom and creation known as Quetzalcoatl introduced the cocoa bean to mankind. It’s likelier that it originated in the Amazon rainforest and wound its way north to Mesoamerica, whose inhabitants figured out they could domesticate, ferment, roast, crush, and mix cocoa with water, chilies, and spices to produce a bitter, intoxicating drink. It then took a boat across the Atlantic, learning Spanish along the way. Europe wasn’t sure what to make of the bitterness until someone spilled a little sugar into the drink. Cocoa quickly swept across the continent, giving rise to large corporations that persist to this day, like Cadbury, Nestle, Hershey, and Lindt.Read More
The main objective of following the Primal Blueprint is to extract the healthiest, happiest, longest and most productive life possible from our bodies – and to look and feel good in the process.
Our 10,000-year-old Primal genes expect us to emulate the way our ancestors ate and moved; and the Primal Blueprint says we should do exactly as they expect. While there are many things we can do (or eat) today that very closely approximate what Grok did to trigger positive gene expression, there are also a number of obstacles that can thwart our attempts to be as Primal as possible. Artificial light prompts us to stay up too late and sleep too little. Electronic entertainment competes for our time when we should be out walking and basking in sunlight. We don’t always have access to ideal foods. We shower too much in water that’s too hot. We use medicines to mask our symptoms instead of allowing our bodies to deal directly with the problem. You get my point. You can’t go back to the paleolithic.
One of my tasks is to find the shortcuts—the easy ways to get the same genetic expression benefits Grok got—but by using 21st century technology or just plain old common sense. Working out in Vibram Fivefingers to simulate going barefoot is an example. Or learning how to spend time in the sun without sunscreen AND without burning. Getting more from a 20-minute full-body exercise routine than from a 3-hour cardio workout is yet another example. And given the lack of certain critical nutrients in even the healthiest diets, finding the best supplements is another.
Here are a few of the best categories of supplements I can recommend to just about everyone:Read More
I’ve been writing about bone broth for a long time. I’ve been drinking it even longer. I’m not sure you can get anything much more primal than a heap of bones cooked for hours into rich, gelatinous glory. Ritual and taste aside, however, I count quality bone broth as an important supplemental food. The copious health benefits are simply too substantial to pass up.
Some of you, I know, are bone broth fans—a few even connoisseurs. You’ve been making your own for decades, maybe with recipes you learned in your grandparents’ kitchen. But what does the average Primal type need to know about bone broth? What goes into making it? What are the distinct health advantages? Are there risks or downsides? What are the alternatives? Finally, what about some recipes? I’m glad you asked….Read More
