L-Theanine And Vitamin Timing

Whole Foods Market Double Strength L-Theanine 200mg Suntheanine Stress Response | eBay

Most people who take vitamin supplements take them all at once, usually at the end of the day after their last meal.

Other than the risk of overloading your digestive tract and most of them being passed instead of used, this isn’t a bad strategy… especially if your vitamins are fat-soluble and you’ve had a large, fairly-fat-rich meal for dinner. Sure, some will likely get passed, but much of what doesn’t directly go to your bloodstream for use could them get stored in whatever fat you end up storing, to be released in your bloodstream later when that fat is tapped for energy. (This in fact is why vitamin capsules contain oils: The oils are digested and stored as fat, and the vitamins absorbed can come along for the ride.)

This is beneficial for runners, triathletes and other endurance athletes. When they go to train soon thereafter, any of that fat that’s aerobically burned will also release those stored vitamins for use… at a time when their body may actually need it.

Now, that said, while I’ve talked about vitamins that can and should go together (like Vitamin K2 and calcium), some nutrients don’t go with other nutrients. And one key nutrient to keep in mind is L-theanine.

Food and Thermogenesis: How what you eat affects your body temperature

Energy produces heat. If you didn’t sleep through science class, they probably taught you this.

There are all sorts of circumstances behind what we now call climate change, the steadily rising temperature of the planet. But one key element is the fundamental existence of more human beings than have ever been on the planet in recorded history.

All humans produce heat. Every mechanical, electrical, chemical anything we have ever done produces heat. Vehicles and other machines produce heat when they operate. Anything we built that moves produces heat. Even the coldest fridges, freezers and air conditioners produce heat to cool what’s inside: The heat is just emitted out of the back or top of the device into the surrounding atmosphere.

And our bodies produce heat. The bigger we are, the more active we are, the more heat we produce. This is a key reason why your perceived temperature is hotter when you’re running than it is when you’re walking or still. You produce a lot more heat when you exercise.

Even the energy required to digest food produces heat. The act of digestion producing this energy is a little something scientists call thermogenesis.

Some foods require more energy from thermogenesis than others. This is one of the keys behind why it’s generally healthier to eat unprocessed meat and vegetables than processed sugar.

Insoluble fiber and most proteins require a lot of digestive energy for the body to digest its nutrients. These foods are highly thermogenic.

Meanwhile, chemically refined sugar is by design quickly digested, as these foods are chemically engineered to not satisfy you hunger and make you crave more of them. These foods are lightly thermogenic.

You can eat 500 calories of sugar cookies, and still be very hungry immediately after eating them. Meanwhile, you can eat 500 calories of steak, and be so full you won’t want another bite of anything for several hours. And woe is the poor soul who tries to eat 500 calories of broccoli… if he even manages to get it all down (1 cup of cooked broccoli is about 60 calories). He will end up spending a regretful amount of time on a toilet at some future point.

Broccoli and other vegetables are among the most thermogenic of foods. Many require more caloric energy to burn them than the calories the vegetables themselves contain!

Now, why bring up global warming when bringing up the thermic effect of food? Is Steven saying that broccoli causes climate change?

Energy Availability and making sure you don’t undereat when training

Currently I’m tinkering with my diet, not necessarily the foods but the meal timing and the calorie macros.

It’s not so much that my weight loss has currently stalled. In fact, it did drop to a month-low 168.9 lbs over the weekend… though it has been tough, slow going to move the average down.

I’m trying to naturally maximize my energy levels, which when I’ve fasted had tended to stay low. This means I need more nutrients around these times, which indicates I should stop fasting.

However, I went back through my RRCA training course materials… mostly because I was walking on a treadmill for an hour and the spiral-bound book was one of the only books I had that I could suitably read while on the treadmill. In any case, I went through the information-laden appendicies and it includes a robust booklet on nutrition by the IAAF.

In the IAAF’s Nutrition materials, they mention an interesting stat: Energy availability. The idea of Energy Availability is that aside from calories burned in exercise, the body has a certain number of calories it needs to rebuild and recover from that exercise.

Twelve (12) Training and Lifestyle Tips For Fat Burning

There’s a lot I could say about fat burning, and there’s a legion of users-guide material throughout the internet world about methods to healthy fat burning (and many more about unhealthy fat burning ideas, which I will not bother to cover). I could write a piece about a dozen topics.

But I think it would help you to get some actionable tips in one place, and perhaps a shorter bit of writing on each of those in one place may help you more in the present. I can always cover all of these topics in additional pieces later.

So instead, I’m going to put a dozen topics into this long post, and succinctly get into why you should make it a standard or best practice.

If you’re trying to burn fat and struggling with it, these tips should help spur things along or keep things moving in the right direction.

Avoid the Novel Coronavirus (and other illnesses)

Coronaviruses are in general quite common. You may actually get one once every year or two. However, we’re experiencing mass panic over the current novel coronavirus strain, which has killed a few thousand people in China among the many thousands infected, and sent entire nations into a panic.

There are a handful of truths regarding this novel coronavirus:

  • Most of the people who contract the worst form of the novel coronavirus will make a full recovery without any required medical intervention, just like most people who get a common cold or the flu.
  • The death rate of the novel coronavirus is actually quite low. About 1-2% of people who have reportedly tested positive for it have died from it, and almost all of the deaths have been in China and Italy, where tens of thousands (again, nearly all known cases) have been diagnosed. Virtually all of the people who have died from the novel coronavirus either have seriously compromised immune systems or live in abjectly unsanitary conditions (and that’s assuming all stats are accurate, which is highly questionable). Sure, I’d be worried about the health of either population, but the vast majority of those reading this are in a much better situation.
  • Regardless of anything anyone does, there’s little people can do to prevent its overall spread, quarantines or not. It’s an airborne virus, and a common type of virus at that. It’s like trying to eradicate or quarantine the flu or common cold. Good luck.
  • The current quarantines are more a product of systemic panic than necessity.
  • Other governments are semi-thoughtlessly following in kind with their own over-reaching quarantines, not realizing they’re parroting a needless overreaction from a totalitarian government. This never minds major events that have elected to cancel said events in response to the hysteria. In most cases, they’re making a panic-driven mistake.

All of this said, this novel coronavirus strain is worth concern, the same way any major flu strain or flu season is worth concern.

As always, there are things you can and should do to safeguard yourself from illness and give your body the best chance to flush and resist that illness should it find its way into your system.

However, I have useful advice beyond the standard “wash your hands, take your vitamin C, avoid crowds, etc”. Here are some tips for you to help your body and immune system withstand any potential exposure to any illness, not to mention the novel coronavirus.

Eating is (literally) stressful

One observation from my Garmin watch is that my stress score goes up after meals. No matter what I eat, how healthy the food I’m eating, my stress levels go up after the meal and stay elevated for at least a couple hours or longer, depending of course on activity and whatever else I’m doing. This is even true if I eat before bed: My stress levels can remain high for up to 2 hours after I drift off to sleep, following a relatively late meal.

My body only shows as resting (meaning a low stress score) in the morning if I have yet to eat breakfast. Despite any hunger pangs, it’s less stressful for me (according to heart rate variability) to be hungry than it is for me to digest a meal after eating. I find I record more restful periods when I intermittent-fast, aka skip breakfast and eat my first meal in the afternoon. Even with the added stimulus of coffee, my stress levels remain in a low resting state.

Garmin’s stress score is a function of heart rate variability, which can indicate activation or rest of your body’s sympathetic nervous system, which activates the body for activity. When the sympathetic nervous system is regularly activated, that indicates your body is under stress. A heart rate that does not vary much is indicative of the sympathetic nervous system being activated.

What does this have to do with eating? The sympathetic nervous system is a component of the autonomic nervous system, which passively operates our organs and hormonal glands. When you eat food, the autonomic/sympathetic nervous system begins diverting blood from other organs to the stomach and other relevant digestive organs to digest your ingested food. This activation of your sympathetic nervous system will continue until your food has been suitably digested and absorbed.

Even if you are laying down and doing absolutely nothing, your sympathetic nervous system during digestion is at work and therefore your heart rate variability at rest is likely small enough to indicate a level of stress to your Garmin. That doesn’t seem fair, but welcome to human biology.

If you live a relatively low-stress existence, eat only 2-3 meals a day, and you’re in good health, this is likely not a big deal. Your heart rate will eventually return to normal variability in a couple hours, and your resting time will read to your tracker as being at rest.

Of course, the vast majority of humanity doesn’t fall into the very thin demographic I just outlined. Most of us deal with some substantial degree of regular stress. Many of us have different meal habits, and many snack or eat enough meals a day that their bodies are digesting food not just throughout the entire day but even after going to sleep. And, of course, most people are not in optimal health.

This never minds people who endurance train, and are already subjecting their bodies to substantial stress through their training. The irony is that, depending on their eating habits, their fueling after workouts may in fact be contributing to their overall (already high) stress levels.

Science incidentally hasn’t laid a hand on this subject in over a decade, so we don’t have a ton of data on why this needs to be a stress reaction let alone if we can change the body’s sympathetic nervous reaction to eating food. So we have to accept that this is reality and work within that.

This incidentally is an underlying reason why intermittent fasting and the old “eat dinner like a pauper” rule* works so well. Fasting by skipping breakfast leads to generally lower stress levels, which improves overall hormonal function. Eating light limits the stress affect on your sleep time, which can improve the quality of that sleep.

Of course, this should not be taken as license to starve yourself and not eat at all. At some points during the day you do need to eventually take in quality nutrition and “take the sack” (so to speak) on the resulting sympathetic stress, because your body needs that nutrition.

This merely points out how the timing of that nutrition can affect your overall sympathetic stress, which in turn can affect your overall health.

Though this was never an intent of the rule, this is one benefit to making sure to eat quality protein/carbs as soon after a hard workout as possible, e.g. the 30 minute and 2 hour windows. Your body undergoes a similar sympathetic stress response after a workout, though the stress ripple effect can last longer than your meals (often, for example, a long run leaves you in a high stress state for the entire rest of the day, even if you spend all day laying down).

Eating as soon as possible and triggering that sympathetic nervous reaction can effectively piggy-back off the other sympathetic nervous reaction recovering from the workout itself. Eating much later could effectively re-start the sympathetic stress reaction, whereas eating right after one has began saves you the trouble of an extra stress reaction, or an extended period of elevated sympathetic stress. You can get back to a normal resting state more quickly, and spend more time in that low-stress rested state than if you had eaten later and had two separate stress-creating episodes for your sympathetic nervous system.

This lends credence to the following ideas:

  • Unless you work out in the morning, or you have health-related reasons not to do so, it’s probably best to intermittent fast by skipping breakfast, nothing but coffee and water.
  • Probably only eat breakfast if doing a morning workout, and probably following that workout.
  • It’s important to consume nutrition within 30 minutes of finishing tougher workouts, and to eat a meal within two hours of finishing those workouts.
  • Regardless of the size of dinner, you want to buffer a couple of hours between the end of dinner and bedtime, to allow digestion and its stress reaction to finish as early in the sleep cycle as possible.
  • Avoid snacking, as it restarts the sympathetic nervous stress reaction. Eat full meals and only full meals, 2-4 times a day.

Primal Endurance: An approach to making low carb endurance running work

Image result for primal blueprintBack in 2011, famous Primal Blueprint guru Mark Sisson wrote a post about how he’d train for a marathon. Mark’s no novice when it comes to distance running: He is in fact a former marathoner! Mark’s conversion to his lower-carb, paleo-style “Primal” approach to eating and lifestyle is in no small part a byproduct of his experience and life lessons from training to race the longest run.

Sisson of course generally discourages any sort of endurance training, prefering a more biologically natural sprint-and-saunter approach to outdoor activity akin to our prehistorical ancestors. Like many paleo-minded humans he’s more into occasional high intensity low duration activity surrounded by lots of regular but very low intensity activity.

This level of activity is of course a better fit for a lower carb Primal style diet, as endurance training traditionally requires a very high carb intake… intake that Sisson’s experience and research taught him can be damaging to your long term health.

However, a lack of carbohydrates can compromise the quality of your endurance workouts, let alone your race performances, since your body typically utilizes glycogen for extended endurance activity.

Sisson historically has preferred to avoid endurance training entirely and focus instead on what he’s found to be a more long-term sustainable lifestyle. His 2011 piece was more of a hypothetical, ‘If I had to train as a Primal disciple to run a marathon this is how I would approach it.’ Sisson’s piece definitely hinted that he had far more intel behind it, and that there was probably a book in him on the subject.

Image result for primal enduranceWell, eventually he did write that book. Primal Endurance by he and Brad Kearns spelled out the ideal combination of the Primal diet and lifestyle with the ideal training approach to maximize your performance in a marathon without the usage of carbohydrates and their glycogen.

I’ve given the book a gradual read over time. While a lot of it reads like sales-letter filler for the Primal Blueprint (which seems superfluous since you probably aren’t reading the book unless you already own, have read and believe in the Primal Blueprint), the deeper material is a compelling and well-written approach to training as a Primal endurance athlete.

Sisson and Kearns of course are hardly the only believers that endurance athletes can succeed with a lower-carb approach. Many ultra-runners have sworn by training low-carb to train their bodies to maximize fat usage in their excessively long races. Other non-ultra runners have sworn by training low-carb as well (I even know a few!).

I’ve long since argued (as many do) that accepting this lifestyle and swearing off most carbohydrates does to some degree limit your capability as a distance runner. In principle, I still find that to be true.

But there’s no denying that long term the traditional endurance diet and lifestyle does take a toll on your hormones and to an accordant degree your health. I recall half marathon champ Ryan Hall being forced to retire in his early 30’s due to wanting to start a family and his training lifestyle compromising his body’s ability to do so. Sure enough, once Hall stopped running, his health rebounded.

I do think there’s a middle ground, mostly that you train in cycles and that you take breaks from training and the diet it demands. However, Sisson and Kearns argue that their recommended lifestyle can be practiced year round, in and out of training, without damaging your race performance.
