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.

Adjusting diet to a work assignment: Detroit Edition

Hello from Detroit Metro, Michigan.

The below is a scenario I’m working through now that I’m in town, and a great example of the thought process required to maintain my exercise and training progress, as well as stabilize my diet while on the road long-term.

Currently I’m working the swing (aka 2nd or evening) shift on assignment. On the one hand this allows a lot of time in the morning to run or exercise. I ran a very comfortable 4.3 miler near my lodging around 10am on Wednesday.

But my assignment also requires I spend a lot of time on my feet walking the facility, and on that Wednesday I burned about 4000 calories that day.

Never minding how tired I felt at the end of the day… while not opposed to burning some fat after bulking up in Vegas, I also was worried I wouldn’t consume enough food (especially protein) to prevent muscle catabolization. I ate a solid pre-work meal, a light snack during work and then a ridiculously large processed meal before going to bed. Despite housing 3300 claories I was well below my overall burn.

Yesterday I decided to not exercise at all, just work that day, to see how much I burned. After a similar workday of activity, I ended up finishing yesterday with 3840 calories burned. I had done nothing physically but walk a facility floor over an 8-9 hour day. On a similar eating schedule I *only* managed 2900 calories, and of course still finished well short of my overall burn.

While not a bad dilemma for someone trying to burn fat, this still presents a dilemma.

Eating a good diet at destination marathons

With Vancouver I was fortunate that the coastal city had a wealth of sushi options. Sushi rolls were an almost perfect combination of carbohydrates (from the rice) and protein (from the fish, seaweed and soy sauce). Sure, they also had markets with lots of produce, which also helped.

But produce is easy to get in most locales. Rich healthy whole food carb and protein sources… not as much.

When I ran the Chicago Marathon last October, this was easy because it was only a few miles down the street from where I lived. I could cook and eat as typically desired right up to and after the race.

But what if I run a marathon in a more remote locale, where there’s not a lot of stores and restaurants? Or even if the race is in a major market, what if pretty much every restaurant available served processed and otherwise unhealthy food that wasn’t going to help me stay ready to run?

The Endurance Diet, and using it to plan a sustainable training diet

EnduranceMatt Fitzgerald’s book The Endurance Diet is probably the best book on basic nutrition for endurance athletes.

Though Matt has written other books on fueling races and workouts, and maintaining an ideal weight for running, his field research of elite athletes around the world finally put together all the pieces of his knowledge into a system to help you assemble a sustainable, repeatable training diet that will effectively fuel your workout while maintaining a healthy weight and lifestyle.

The book goes into more useful detail on what these are about, but Fitzgerald says all elite athletes eat successfully around key core habits: To eat a healthy variety of foods, provided they are high quality, to eat a lot of carbs, get enough to eat, and to eat “individually”, aka eat the diet that works for you rather than eat someone else’s prescribed diet.

Quick thoughts on what causes weight gain when running

If you struggle with weight gain while running, your problem may not necessarily be overeating.

In fact, you need all the nutrients you can get during high volume training. Cutting calories might be the worst thing you can do for your recovery.

Your culprit is not how much you’re eating, but the type of food you’re eating. For most of us, the easiest and most readily available form of satisfying food is processed. It comes out of a box or package. It’s either ready to eat or cooks quickly. It was chemically engineered in a lab and factory to taste good.

This food is high in sodium and a variety of additives. The organs’ struggle to process and coexist with these (non-)”nutrients” inflames your entire body and leads to your prime culprit: Water retention.

Water has weight. Drink a 16 oz glass of water and guess what? You just gained one pound. Ideally, your body urinates, sweats or evaporates this newfound pound out at some point soon.

But when your body is inflamed, it responds by retaining water to surround and protect your organs. The more processed food you eat, the more often you eat it, the more water your body continously retains to buffer your organs from all the chemical byproducts of the garbage you’re eating.

This is why when people try to diet, or clean up their diets, they lose a bunch of weight early on. A cleaner diet eliminates the inflammation and the need to water-protect organs. Your body begins to flush the excess retained water out. Whoosh!

(And yes, you may notice you’ve got to pee a lot more after you start. There goes all that retained water!)

This is also why people on diets see their weight loss slow after an early surge of lost weight. They weren’t losing fat early on. They were losing retained water.

Bakc to the point: If you’re gaining weight as a runner, you almost certainly are eating an excess of processed food. You may have your reasons for eating as you do. Your body is the ultimate scoreboard and won’t lie about what you’re eating and drinking.

Simply put, you can stop and reverse your weight gain by eating more unprocessed whole and natural foods. Eat for the whoosh, get yourself back on track, and stay back on track.
