For today’s edition of Dear Mark, I’m answering five questions taken from this Twitter thread. First, does collagen offer anything special above and beyond glycine? Second, what’s the relationship between keto and gallstones? Third, do I recommend eating raw liver, and why or why not? Fourth, why does one reader’s scalp itch when eating stevia? And finally, what’s the best way to lose fat and gain muscle at the same time?
The fitness world is booming these days. You can see it in the popularity of CrossFit boxes, obstacle course and endurance events, and record-breaking gym construction. It’s encouraging. Inspiring even. But there’s also a downside to the rising gym memberships and event registrations. There are still too many people dealing with recurring patterns of breakdown, burnout, illness and injury. More people are trying to do the right thing, but the flawed approaches they often gravitate to end up derailing them.
Nonetheless, there are changes afoot. It’s an evolution of thinking that’s slowly spreading its way through fitness circles. More forward-thinking coaches, trainers, and researchers are helping right the wrongs of the fitness boom with a general rejection of the “more is better” approach for one that respects the importance of balancing stress and rest, one that moves toward an intuitive approach to workout planning.
For today’s edition of Dear Mark, I’m answering another round of questions asked by Twitter followers. First up is a three-parter, including a query about extra virgin olive oil, one about supplements everyone should take, and one about autoimmune arthritis in an athlete. Second, I cover whether sauna is a hormetic stressor or a way to relax (or both). Next, I give my recommendation for staying keto or carnivore while camping (it’s a quick one). And finally, I explore a potential protocol for using exogenous ketones to curb autoimmune inflammation.
For my entire athletic career, I considered the gold standard of recovery to be sleeping, resting on the couch watching T.V., and generally being still and inactive. Come on, what could be more effective than couch potato mode to recover from the hormonal and inflammatory stresses of marathon training runs or long days of extreme swim-bike-run workouts? I’m kidding (mostly), but it’s not a total exaggeration. Our understanding of fitness recovery has grown exponentially since I was in the elite arena, and it’s exciting to see new and better approaches taking root that genuinely speed recovery and stave off burnout. I’m sharing two such techniques today. They’re simple, mostly free, and accessible to anyone with the most basic fitness opportunities and venues.
Collagen or whey. Which should you choose?
For years, collagen/gelatin was maligned by bodybuilding enthusiasts as an “incomplete protein” because it doesn’t contain all the essential amino acids, nor does it contribute directly to muscle protein synthesis. There’s definitely truth to this. If you ate nothing but gelatin for your protein, you’d get sick real quick. That’s exactly what happened to dozens of people who tried the infamous “liquid protein diet” fad of the 70s and 80s, which relied heavily on a gelatin-based protein drink. Man—or woman—shall not live by collagen alone.
As for whey, it’s an extremely complete protein. It’s one of the most bioavailable protein sources around, a potent stimulator of anabolic processes and muscle protein synthesis. I consider it essential for people, especially older ones in whom protein metabolism has degraded, and for anyone who wants to boost their protein intake and get the most bang for their buck.
This said, which is best for your needs today? Let’s take a look….
When you stop to think about it, mushrooms are remarkable.
They’re closer to animals than plants on the tree of life.
They can break down plastic and petroleum.
The single largest organism on the planet is an underground honey fungus spanning almost 3 miles in the the state of Oregon.
They carry messages along their underground fungal networks using neurotransmitters that are very similar to the ones our brains use.
They’re a kind of “forest internet” which plants and trees use to communicate with each other.
And, as it turns out, they possess and confer some very impressive health and therapeutic effects. Several years ago, I highlighted the culinary varieties and explored their considerable health benefits. Go read that, then come back here because I’m going to talk about the different types of adaptogenic mushrooms today. These are the real heavy hitters, the ones that appear to supercharge immune systems, stimulate neuronal growth, improve memory and focus, pacify the anxious mind, increase the libido, and enhance sleep quality.
I left the pro athlete world a long time ago. I no longer compete. I don’t train with the intensity and volume it’d take to win races. But I do pay attention to what’s going on in that world, and I still have a lot of friends who never left it. Developments there often foreshadow developments in the rest of the health world. And after things like keto, MCT oil/ketones, and collagen, the performance hack that’s blowing up among elite athletes is CBD oil. Almost everyone I talk to who puts in serious training and competing time (in a variety of sports and pursuits) is dabbling with CBD.
What are they using it for?
For today’s edition of Dear Mark, I’m answering three questions from readers. First, what’s the deal with exercise-induced asthma? Is there anything we can do to lessen its impact and incidence? Second, is CBD oil helpful for diabetics? And finally, do bodyweight exercises always require warm-ups? What about workouts in general—do you need to warm-up before every single session?
Let’s find out:
For today’s edition of Dear Mark, I’m answering a couple of questions from the comment sections of the last couple weeks. First, it’s been established that fasting and exercise both raise growth hormone. What about fasted exercise—does that have an even stronger effect? And what about continuing to fast after your fasted workout? Then, I discuss the inevitability (or not) of wear and tear on the arteries from blood flow-induced shear stress. Is shear stress “bad,” or do certain factors make it worse?
Let’s dig in.
For today’s edition of Dear Mark, I’m answering six questions from readers. First, is funding from a biased source sufficient to negate a study’s results? Second, what are some good high intensity interval training workouts that people might not have considered? Third, what can someone recovering from an ACL tear do for HIIT without triggering knee pain flareups? Fourth, how do I like to eat spinach? And finally, how and when do I like to take collagen?
